+ + + + + + +

Incompatibilities

+ +

+Following are a few modifications to the library that unfortunately +are incompatible with previous versions of the library, but which we +deem necessary for the future maintainability of the +library. Unfortunately, some of these changes will require +modifications to application programs. We apologize for the +inconvenience this causes. +

+ +
    +
  1. Removed: The base class to the iterative linear solvers, Solver, + received a SolverControl object upon construction and had a member + function control() that returned a reference to the + object previously passed in. The class now no longer stores such + a reference, and consequently, the function has been removed. +
    + (Wolfgang Bangerth, 2014/10/24) +
    2. + +
  2. Removed: The constructor of the Utilities::MPI::MPI_InitFinalize + class used to interpret a last argument equal to numbers::invalid_unsigned_int + as "create as many threads as there are processor cores on the current + system" for each MPI process. If there were multiple MPI processes on a + given node, this would lead to (sometimes massive) overallocation of resources + because every MPI process would create as many threads as there are cores. + This has now been changed: an argument equal to numbers::invalid_unsigned_int + is now interpreted as "subdivide the available cores between all MPI + processes running on the current system and let each process create as many + threads as cores were allocated to it". +
    + (Wolfgang Bangerth, 2014/09/16) +
    3. + +
  3. Removed: CMake's configure phase no longer calls back into testsuite + subprojects. If a build directory is reconfigured the testsuite has to be + regenerated by hand using make regen_tests. +
    + (Matthias Maier, 2014/07/16) +
    4. + +
  4. Removed: Class PointerMatrixBase (and, consequently, the various + classes derived from it) had comparison operators that were intended to + work generically for any kind of derived class. However, the implementation + used a scheme that was not robust enough to handle the various situations + that derived classes implemented and, consequently, was not always correct. + These operators were not previously used inside the library and, likely, + were not widely used in applications either. They have now been removed. +
    + (Wolfgang Bangerth, 2014/02/15) +
    5. + +
  5. The change from functionparser to muparser introduced a small number of + incompatibilities: units, use_degress, and recursion with 'eval' are no + longer supported. Comparing for equality is done using '==' instead of '='. +
    + (Timo Heister, 2014/02/10) +
    6. + +
  6. Changed: The various classes generating graphical output, such + as DataOut or DataOutStack, are all derived from a common interface + class DataOutInterface which, in turn was derived from DataOutBase + through private inheritance. Because we frequently also + access the (public) members of this private base class this has tripped + up most every compiler we know of at one point or another. Furthermore, + because DataOutBase was a class that only defined static member functions + and had not member variables, there was really no reason for this + construct. +
    + For these reasons, DataOutBase is now just a regular namespace and the + inheritance is gone. For the most part, this should not lead to any + incompatibilities except in cases where you accessed members of + DataOutBase through their derived classes. For example, it was possible + to write DataOut::Patch even though the + Patch class is actually declared in DataOutBase. Since + the inheritance is now gone, this is no longer possible and one + actually has to write DataOutBase::Patch instead. Using this form + turns out to be compatible also with older versions of deal.II. +
    + (Wolfgang Bangerth, 2014/02/01) +

General

+ + +
    +
  1. New: Several parts of the library have been adjusted to allow + compilation with Microsoft Visual Studio. Unfortunately, not all + of the library can be compiled yet. +
    + (Lukas Korous, 2014/12/03) +
    2. + +
  2. New: Added support for OpenCASCADE (www.opencascade.org) + library, which allows the use of arbitrary IGES files to describe + the boundary of a mesh. The use of the new classes is described in + the new Step-54. +
    + (Luca Heltai, Andrea Mola, 2014/10/31) +
    3. + +
  3. New: The classes implementing iterative solvers have gained + a mechanism by which it is possible to observe the progress of + the iterations, or to influence when to stop the iteration. The + documentation of the Solver class now contains an extended + discussion and example of this functionality. +
    + (Wolfgang Bangerth, 2014/10/24) +
    4. + +
  4. New: There is now a section in the introduction of step-36 that + discusses the interaction of Dirichlet boundary values and the solution + of eigenvalue problems. +
    + (Denis Davydov, Wolfgang Bangerth, 2014/09/28) +
    5. + +
  5. New: The glossary now contains an extensive entry on ghosted and + non-ghosted vectors (see @ref GlossGhostedVector ). +
    + (Wolfgang Bangerth, 2014/09/27) +
    6. + +
  6. New: MappingQ is now aware of + Manifold, i.e., we can use high order mappings that + actually follow the geometry also on the interior of codimension + zero meshes. +
    + (Luca Heltai, 2014/09/13) +
    7. + +
  7. New: The new tutorial program step-52 explains how to use the + new time stepping methods. +
    + (Bruno Turcksin, Damien Lebrun-Grandie, 2014/09/12) +
    8. + +
  8. New: The new tutorial program step-53 explains how to deal with + complicated geometries. +
    + (Wolfgang Bangerth, Luca Heltai, 2014/09/02) +
    9. + +
  9. Changed: Namespace std_cxx1x has been renamed to namespace + std_cxx11 to match the fact that the corresponding C++ standard + was approved back in 2011. The old namespace name was retained for + backward compatibility but is now deprecated. +
    + (Wolfgang Bangerth, 2014/09/01) +
    10. + +
  10. New: Most of the operations done on Vector (like add, sadd, etc.) + are now vectorized (SIMD) using OpenMP 4.0. +
    + (Bruno Turcksin, 2014/08/25) +
    11. + +
  11. Updated: The version of BOOST that comes bundled with deal.II has + been updated to 1.56.0. +
    + (Wolfgang Bangerth, 2014/08/19) +
    12. + +
  12. Fixed: Newer versions of GCC (e.g. 4.9.x) are no longer compatible + with BOOST 1.46. Consequently, the CMake scripts now require at least + BOOST 1.48 in order to use a BOOST version found on the system. If no + installed BOOST library is found, or if the version is older than 1.48, + CMake will simply take the one that comes bundled with deal.II. +
    + (Wolfgang Bangerth, 2014/08/19) +
    13. + +
  13. New: There is now a documentation module that describes + deal.II's support for and interaction with the + @ref CPP11 "C++11 standard". +
    + (Wolfgang Bangerth, 2014/08/14) +
    14. + +
  14. New: Added support for curved interior cells for all Triangulation + dimensions. +
    + A new Manifold class was introduced which only contains the + interface needed by Triangulation to refine objects, leaving all boundary + related functions in the class Boundary, which was made + derived from Manifold. +
    + This new construction allows for curved interior cells, and custom refinement + strategies (see, for example, the new tutorial program step-53). + At the moment the following Manifolds are supported: +
      +
    • FlatManifold: This class replaces the old + StraightBoundary, and it adds support for periodic + manifolds. This is the simplest class one can use to create new Manifold classes; +
      • +
    • ManifoldChart: This is one of the most general Manifold + one can think of. The user can overload the functions ManifoldChart::pull_back() and + ManifoldChart::push_forward(), to obtain a very general curved geometry, following + concepts typical of elasticity; +
      • +
    • SphericalManifold: A simple implementation of spherical coordinates + transformations. This manifold allows hyper shells with curved interior cells which + follow the natural shape of the shell; +
      • +
    +
    + The functions + Triangulation::set_boundary() and Triangulation::get_boundary() can still be used to + set and get Boundary objects instead of Manifold ones. For the get function, an exception + is thrown if a conversion to a valid Boundary class cannot be made on the fly. +
    + (Luca Heltai, 2014/08/06) +
    15. + +
  15. Ported: The build system now supports CMake 3.0. +
    + (Matthias Maier, 2014/07/15) +
    16. + +
  16. New: Added support for curved interior boundaries, and general + manifold id description. +
    + A new attribute was added to each triangulation object + (types::manifold_id) which allows one to specify a manifold + description, much in the same way we do for boundaries, also for + interior edges and faces. At the moment this information is used + only for objects of topological dimension less than spacedim, but a + generalization of the class Boundary is on its way to + allow also curved cells. +
    + For the moment, full backward compatibility is granted, and one can + keep using the old Boundary, together with + Triangulation::set_boundary(), and Triangulation::get_boundary() + methods. However, this change suggests to use the types::boundary_id associated + with each boundary face to indicate only boundary condition types, and + it allows to separate the geometric meaning from the physical meaning. The + suggested usage is + - types::boundary_id is used for the physical meaning + - types::manifold_id is used for the geometric meaning. +
    + (Luca Heltai, 2014/07/14) +
    17. + +
  17. New: Tutorial programs (and a few other places) are now cross-linked + to their corresponding video lectures. +
    + (Wolfgang Bangerth, 2014/07/10) +
    18. + +
  18. Changed: The functionparser library bundled with deal.II got replaced + by the muparser library. +
    + (Timo Heister, 2014/02/10) +
    19. + +
  19. Changed: It was possible to call DoFCellAccessor::set_active_fe_index() + on non-active cells. However, this made no sense: Since degrees of + freedoms only exist on active cells + for hp::DoFHandler (i.e., there is currently no implementation + of multilevel hp::DoFHandler objects), it does not make sense + to assign active FE indices to non-active cells since they + do not have finite element spaces associated with them without + having any degrees of freedom. +
    + The same of course is true for asking for the finite element active + on a non-active cell, i.e. using the functions + DoFAccessor::active_fe_index() and + DoFAccessor::get_fe(). All of these functions now produce exceptions on + non-active cells. +
    + (Wolfgang Bangerth, 2014/01/24) +
    20. + +
  20. New: deal.II now links with the + BOOST + Iostreams library (at least if the libz and libbz2 libraries + can be found that are necessary for BOOST Iostreams). + Among many other things, this allows to easily + read files that have been compressed, as in the following code snippet: + @code + #include + #include + #include + + ... + + boost::iostreams::filtering_istream in; + in.push(boost::iostreams::basic_gzip_decompressor<>()); + in.push(boost::iostreams::file_source("myfile.gz")); + + int i; + in >> i; + @endcode + More documentation on how to use BOOST Iostream can be found + in the documentation link referenced above. +
    + (Wolfgang Bangerth, 2013/12/21) +
    21. +
+ + + + + +

Specific improvements

+ +
    +
  1. Fixed: CMake now correctly detects -Wno-... support for gcc. +
    + (Matthias Maier, 2014/12/11) +
    2. + +
  2. New: The FE_Q and FE_Q_Hierarchical classes now include pictures + of their 2d shape functions in the class documentation. +
    + (Manuel Quezada de Luna, Wolfgang Bangerth, 2014/12/09) +
    3. + +
  3. Fixed: Calling DoFRenumbering::Cuthill_McKee threw an exception + whenever one of the processors of a parallel triangulation did not own + any degrees of freedom. +
    + (Michal Wichrowski, Wolfgang Bangerth, 2014/12/04) +
    4. + +
  4. Fixed: Serializing an object of type DoFHandler did not work without + including additional header files. +
    + (David Wells, Wolfgang Bangerth, 2014/11/26) +
    5. + +
  5. New: The class FEEvaluation with its fast tensor evaluation routines + can now be initialized from a mapping, a finite element, a quadrature, and + update flags on the fly similar to FEValues. This provides an alternative + entry point to these routines without the need to create a MatrixFree data + object. +
    + (Martin Kronbichler, 2014/11/20) +
    6. + +
  6. New: Complete the interface for periodic boundary conditions. + Now, it is possible to specify an additional (geometric) rotation matrix along + with vector components that should be rotated when applying periodic boundary + conditions (or alternatively, directly a transformation matrix working + directly on dofs). With this it is now possible to e.g. compute Stokes flow + on a quarter pie with periodic boundary conditions and the velocity correctly + transformed. +
    + (Daniel Arndt, Matthias Maier, 2014/11/19) +
    7. + +
  7. Improved: Vector updates in PreconditionChebyshev based on deal.II's own + vectors are now vectorized with OpenMP 4.0 SIMD pragmas. +
    + (Martin Kronbichler, Bruno Turcksin, 2014/11/17) +
    8. + +
  8. New: Added support for STEP files in the OpenCASCADE + wrappers. STEP files can now be imported and exported respectively + with the OpenCASCADE::read_STEP() and OpenCASCADE::write_STEP() functions. +
    + (Andrea Mola, 2014/11/12) +
    9. + +
  9. New: Timer now has get_lap_time() which returns the time + lapsed between the last start()/stop() cycle. +
    + (Fahad Alrashed, 2014/11/09) +
    10. + +
  10. New: GridTools::get_locally_owned_vertices() allows to query + which vertices of a triangulation are owned by the current + processor. +
    + (Wolfgang Bangerth, 2014/11/09) +
    11. + +
  11. New: parallel::distributed::Triangulation::communicate_locally_moved_vertices() + allows to + update vertex positions that have been moved just locally on distributed + meshes. GridTools::distort_random now works for distributed meshes and + hanging nodes in 3D as well. +
    + (Daniel Arndt, 2014/11/06) +
    12. + +
  12. New: TableHandler objects can be cleared - i.e. reset to a + zero-sized state. +
    + (Fahad Alrashed, 2014/11/09) +
    13. + +
  13. New: The FE_Nothing class now has a second template argument + corresponding to the space dimension in which the mesh is embedded, + like many other classes. This allows to use this element in codimension + one cases as well now. +
    + (Wolfgang Bangerth, 2014/11/05) +
    14. + +
  14. Fixed: Using the FEEvaluation framework did not work for + scalar elements in 1d because there were conflicting partial + specializations. This is now fixed. +
    + (Shiva Rudraraju, 2014/11/04) +
    15. + +
  15. New: There is now a macro DEAL_II_VERSION_GTE + that can be used to test whether the deal.II version is greater + than or equal a particular version number. This is useful if you + need to make application programs compatible with different + deal.II releases. +
    + (Wolfgang Bangerth, 2014/10/31) +
    16. + +
  16. New: The vector classes in deal.II (including Trilinos and PETSc + wrappers) now have a new method x.add_and_dot(factor,v,w) which performs + x.add(factor,v) and subsequent inner product of x with another vector + w. This operation occurs in some iterative solvers; by a combined operation, + reduced memory transfer and thus higher performance are enabled. +
    + (Martin Kronbichler, 2014/10/27) +
    17. + +
  17. Improved: Inner products and norms on deal.II's own vector classes now + use vectorization through VectorizedArray if available. +
    + (Martin Kronbichler, 2014/10/27) +
    18. + +
  18. Changed: PETSc and Trilinos vectors with ghost entries can now be reset to zero + using = 0.0; +
    + (Timo Heister, 2014/10/14) +
    19. + +
  19. New: The new function FiniteElement::get_associated_geometry_primitive() allows to + query whether a given degree of freedom is associated with a vertex, line, + quad, or hex. +
    + (Wolfgang Bangerth, 2014/09/26) +
    20. + +
  20. Fixed: The vector and array versions of Utilities::MPI::sum() and + Utilities::MPI::max() produced segmentation faults with some MPI implementations + if the input and output arguments were the same. This is now fixed. +
    + (Wolfgang Bangerth, 2014/09/29) +
    21. + +
  21. Fixed: Trying to have FE_Q(p) and FE_DGQ(r) elements next to each + other in an hp::DoFHandler object led to assertions saying that these two + elements don't know how to compute interface constraints where such + elements touch. This has now been fixed: FE_DGQ is a discontinuous element, + so there cannot be any interface constraints at all. +
    + (Wolfgang Bangerth, 2014/09/26) +
    22. + +
  22. Fixed: The function TrilinosWrappers::VectorBase::sadd(double factor, + VectorBase &v) erroneously added factor*v instead of scaling the calling + vector by factor. This is now fixed. +
    + (Martin Kronbichler, 2014/09/26) +
    23. + +
  23. Fixed: The function TrilinosWrappers::SparseMatrix::add(double factor, + SparseMatrix &rhs) produced wrong results and ran into an exception if the + rhs matrix included off-processor column entries. This is now fixed. +
    + (Martin Kronbichler, 2014/09/21) +
    24. + +
  24. New: The function Threads::Task::joinable() can be used to verify whether + a task object can be joined or not. +
    + (Wolfgang Bangerth, 2014/09/17) +
    25. + +
  25. New: Added two optional parameters to TriaAccessor::center() + and a new method TriaAccessor::intermediate_point(). + They allow to query for a + geometrically coherent center, or ask for arbitrary points on the + underlying Manifold, given the dim coordinates in the reference + element. + Triangulation was refactored internally to use the new + TriaAccessor::center() interface when querying for new points. +
    + (Luca Heltai, 2014/09/13) +
    26. + +
  26. Improved: Optimize construction of high-order FE_Nedelec by moving out some + non-essential computations. Namely, construct restriction and prolongation + matrices on first request. This reduces time spent in FE_Nedelec constructor + substantially. +
    + (Alexander Grayver, 2014/08/22) +
    27. + +
  27. New: There is now a GridGenerator::flatten_triangulation() + taking a Triangulation as input and returning + a Triangulation as output. The output + triangulation will contain a single level with all active + cells of the input triangulation, and will be topologically + equivalent to the input triangulation. If the two space dimensions + are equal, then this function will copy the triangulation + removing all levels, e.g., flattening it. If the two space dimensions + are different, then this function will copy the vertices only + up to the smallest space dimension parameter.
    + Using this function, you can create a Triangulation<2,3> from + a Triangulation<2,2> or project to the plane z=0 your + Triangulation<2,3>. No checks are performed on the validity of + the resulting Triangulation. +
    + (Luca Heltai, 2014/08/19) +
    28. + +
  28. Changed: The functions GridTools::extract_boundary_mesh() and + GridTools::create_union_triangulation() have been moved to + GridGenerator::extract_boundary_mesh() and + GridGenerator::create_union_triangulation() since, conceptually, they + generate meshes. The old functions have been retained but are now + deprecated. +
    + (Wolfgang Bangerth, 2014/08/19) +
    29. + +
  29. New: TriaAccessor::measure() is now also implemented for faces of + 3d cells as long as the face is planar. +
    + (Kevin Drzycimski, 2014/08/19) +
    30. + +
  30. Fixed: Support SLEPc 3.5 by disabling SDFOLD spectrum transformation type + that has been removed from SLEPc. Therefore, TransformationSpectrumFolding + cannot be used with newer SLEPc versions. +
    + (Alexander Grayver, 2014/08/15) +
    31. + +
  31. New: To better support applications that want to use C++11's + range-based + for loops, there are now functions Triangulation::cell_iterators(), + Triangulation::all_cell_iterators() and similarly in classes DoFHandler + and hp::DoFHandler + that return a range object that can then be used in range-based for loops. + The underlying implementation uses the new IteratorRange class. +
    + See the new @ref CPP11 "C++11" page for more information. +
    + (Wolfgang Bangerth, 2014/08/07) +
    32. + +
  32. New: The new class FunctionManifold allows arbitrary manifold descriptions, in which you have + an explicit Function for the ManifoldChart::push_forward() + method, and an explicit Function for ManifoldChart::pull_back() + method (or an expression for both). In these cases, you can construct a + Manifold description on the fly. +
    + (Luca Heltai, 2014/08/07) +
    33. + +
  33. New: Added CylindricalManifold description. +
    + This class allows refinement of cylindrical manifolds. It is a good + companion for GridGenerator::cylinder() and the perfect companion + for GridGenerator::cylinder_shell(). +
    + (Luca Heltai, 2014/08/06) +
    34. + +
  34. New: TrilinosWrappers::PreconditionAMG can now be initialized from an + object of type Epetra_RowMatrix, which allows using it with more arbitrary + matrix objects, including matrix-free methods. +
    + (Martin Kronbichler, 2014/08/06) +
    35. + +
  35. Fixed: The FE_Nedelec element computed face interpolation matrices + wrongly for elements of order p>1. This also led to trouble computing + hanging node constraints in the context of hp adaptivity. This is now fixed. +
    + (Alexander Grayver, 2014/08/05) +
    36. + +
  36. New: The function GridTools::get_patch_around_cell() extracts + the set of cells that surround a single cell. The new functions + DoFTools::count_dofs_on_patch() and DoFTools::get_dofs_on_patch() + then help set up local problem on patches. +
    + (Arezou Ghesmati, Wolfgang Bangerth, 2014/07/29) +
    37. + +
  37. Fixed: Utilities::string_to_int() and + Utilities::string_to_double() did not catch if the + string given started with an integer or double but contained additional + text. They now throw an exception if this happens. +
    + (Wolfgang Bangerth, 2014/07/20) +
    38. + +
  38. New: The function GridOut::write can now be used also in + the codimension one case. +
    + (Luca Heltai, 2014/07/18) +
    39. + +
  39. New: The Function classes now take an additional optional + template argument, specifying the type of number to use, which defaults + to double. +
    + (Luca Heltai, 2014/07/18) +
    40. + +
  40. New: The GridReordering::reorder_cells() function used a + numbering format for the vertices in a cell that was last used in + deal.II version 5.2. This format is still used internally, but + the function now also understands the numbering that has been + used in deal.II ever since. The choice is made by an additional + argument to the function that defaults to the old-style + format for backward compatibility. +
    + (Wolfgang Bangerth, 2014/07/14) +
    41. + +
  41. New: There are now functions GridOut::write_vtk() and + GridOut::write_vtu() that can + write a mesh in VTK/VTU format. +
    + (Wolfgang Bangerth, 2014/07/14) +
    42. + +
  42. Fixed: PETSc up to at least version 3.5 has a bug where it does + not zero-initialize the ghost elements of a newly created ghosted + parallel vector. This is now worked around inside deal.II. +
    + (Wolfgang Bangerth, Michal Wichrowski, 2014/07/12) +
    43. + +
  43. Improved: The Trilinos direct solver, TrilinosWrappers::SolverDirect, + now takes a string to select among the available Amesos solvers. Moreover, + the solver now also supports deal.II's distributed vectors. +
    + (Uwe Köcher, Martin Kronbichler, 2014/07/09) +
    44. + +
  44. New: There are now three new preconditioner classes + TrilinosWrappers::PreconditionBlockJacobi, + TrilinosWrappers::PreconditionBlockSSOR, and + TrilinosWrappers::PreconditionBlockSOR that work on small dense blocks of + the global matrix instead of the point-wise relaxation methods in + TrilinosWrappers::Precondition{Jacobi,SSOR,SOR} that work on each row + separately. +
    + (Martin Kronbichler, 2014/07/04) +
    45. + +
  45. Fixed: Some versions of DoFTools::extract_boundary_dofs() were + not instantiated for some combinations of arguments. This could lead + to missing symbol errors during linking of applications on some + platforms and with some compiler versions. This is now + fixed. +
    + (Wolfgang Bangerth, 2014/07/04) +
    46. + +
  46. Fixed: GridGenerator::merge_triangulations sometimes produced invalid + orientations of faces. This is now fixed. +
    + (Daniel Arndt, 2014/06/30) +
    47. + +
  47. Fixed: TrilinosWrappers::PreconditionAMG did not read user-provided + constant modes (aka null space) when the null space dimension is one but not + just the trivial one vector. This is now fixed. +
    + (Martin Kronbichler, 2014/06/30) +
    48. + +
  48. Simplified interfaces for FEEvaluation: Previously, the user had to + select the appropriate kernel (FEEvaluation, FEEvaluationGeneral, + FEEvaluationDGP, FEEvaluationGL) for the matrix-free evaluation + routines. This made it difficult to write compact code that needs to select + between different elements. Therefore, all the functionality has been merged + into FEEvaluation and one should only use FEEvaluation, while the other + interfaces have been marked deprecated and will be removed in a future + version. The internal data structures for the various special cases have + been kept in order to provide for the most efficient routines, and are + selected at construction of FEEvaluation. +
    + (Martin Kronbichler, 2014/06/27) +
    49. + +
  49. Bugfix: TBB specific include directories have to be added to the + list of user include directories because of direct inclusion of header + files in base/thread_local_storage.h. +
    + (Matthias Maier, Kainan Wang, 2014/06/25) +
    50. + +
  50. Improved: GridGenerator::hyper_cube() accepts a + colorize argument. +
    + (Guido Kanschat, 2014/06/23) +
    51. + +
  51. New: %Functions DoFTools::extract_locally_relevant_dofs(), + parallel::distributed::GridRefinement::refine_and_coarsen_fixed_number() and + parallel::distributed::GridRefinement::refine_and_coarsen_fixed_fraction() are + now also instantiated for objects of codimension 1. +
    + (Michal Wichrowski, 2014/06/15) +
    52. + +
  52. New: There are now functions Triangulation::has_hanging_nodes() + and parallel::distributed::Triangulation::has_hanging_nodes(). +
    + (Denis Davydov, 2014/06/15) +
    53. + +
  53. New: There is now function Triangulation::n_global_active_cells(). +
    + (Denis Davydov, 2014/06/19) +
    54. + +
  54. New: The class FEEvaluation now provides optimized matrix-free + evaluation routines for FE_Q_DG0 elements. +

    55. + +
  55. Bugfix: Filter libclang_rt* from the PETSc link line. +
    + (Matthias Maier, 2014/06/04) +
    56. + +
  56. Improved: ParameterHandler parsing added to DoFOutputOperator +
    + (Guido Kanschat, 2014/06/03) +
    57. + +
  57. Improved: Algorithms::ThetaTimestepping and other operators now use AnyData + to communicate with operators they rely on. This way, time step data + can be forwarded using the same mechanism, and no complicated back + access to member data is required + anymore. MeshWorker::IntegrationInfo uses AnyData as well. +
    + (Guido Kanschat, 2014/06/03) +
    58. + +
  58. Bugfix: CMake: Also clean CMAKE_MODULE_PATH prior to call to + FIND_PACKAGE(Boost) inside FindBOOST.cmake because apparently + "Boost" == "BOOST" for the Mac file system... +
    + (Matthias Maier, 2014/05/28) +
    59. + +
  59. Improved: CMake: Search results and error conditions for external + libraries are now much more verbose. Added an MPI sanity check. +
    + (Matthias Maier, 2014/05/28) +
    60. + +
  60. Fixed: The MatrixTools::apply_boundary_values() variant that works + on PETSc matrices could produce a deadlock in parallel if one processor + had no boundary values to apply. This is now fixed. +
    + (Michal Wichrowski, 2014/05/19) +
    61. + +
  61. New: AnyData::try_read() is a function that allows users to check + whether an entry exists and get a pointer to it without throwing an + exception in case of failure. +
    + (Guido Kanschat, 2014/05/16) +
    62. + +
  62. New: The GMRES solver of deal.II can now write an estimate of + eigenvalues to the log file, in analogy to the CG solver. This is enabled + by the flag SolverGMRES::AdditionalData::compute_eigenvalues. +
    + (Martin Kronbichler, 2014/05/11) +
    63. + +
  63. New: The GridIn::read_vtk() function places fewer restrictions + on the VTK files it wants to read and should, consequently, be able + to read more correctly formatted VTK files than before. +
    + (Giorgos Kourakos, 2014/05/08) +
    64. + +
  64. New: There is now a QSorted quadrature which takes an + arbitrary quadrature at construction time and reorders the quadrature + points according to the weights, from smaller to bigger. This should + improve stability of higher order polynomial integration. +
    + (Luca Heltai, 2014/05/07) +
    65. + +
  65. New: The class VectorizedArray now provides methods + VectorizedArray::load(ptr) to read from arbitrary pointer addresses and + VectorizedArray::store(ptr) to write to arbitrary pointer addresses, + as opposed to the data layout of VectorizedArray that requires pointers + to be aligned by the size of the array in bytes. This also circumvents + a (rare) compiler optimization bug with gcc-4.6 on SSE code in combination + with function calls, e.g. to std::sin. +
    + (Martin Kronbichler, 2014/05/05) +
    66. + +
  66. Changed: Namespace SparsityTools had a local typedef size_type + that was set equal to types::global_dof_index. This typedef has been removed + and we now use SparsityPattern::size_type wherever applicable as this is the + type we really want to use. (The code worked previously because + types::global_dof_index and SparsityPattern::size_type happen to be the same + as far as the underlying type is concerned; however, they are different + semantically.) +
    + (Wolfgang Bangerth, 2014/05/04) +
    67. + +
  67. Updated: The step-16 tutorial program was updated to the new layout + multigrid objects and thus avoids using deprecated interfaces. +
    + (Martin Kronbichler, 2014/05/03) +
    68. + +
  68. Fixed: FE_DGQArbitraryNodes::has_support_on_face was broken when + polynomials with support points not on the element boundary were used. + This is now fixed. +
    + (Martin Kronbichler, 2014/04/30) +
    69. + +
  69. Fixed: parallel::distributed::Triangulation::load now has an + additional parameter autopartition to control p4est's behavior of + rebalancing triangulations between MPI nodes upon reading. It is + particularly useful to disable this behavior when data is stored + separately (examples for this are in the regression tests mpi/p4est_save_0?). +
    + (Alexander Grayver, Matthias Maier, 2014/04/26) +
    70. + +
  70. Fixed: GridTools::find_active_cell_around_point() could get into an infinite + loop if the point we are looking for is in fact not within the domain. This is now + fixed. +
    + (Giorgos Kourakos, Timo Heister, Wolfgang Bangerth, 2014/04/14) +
    71. + +
  71. Changed: TableBase now uses AlignedVector for storing data + instead of std::vector, which allows its use for VectorizedArray + data fields which require more alignment. +
    + (Martin Kronbichler, 2014/04/09) +
    72. + +
  72. Improved: Piola transformation for FE_BDM is now active. +
    + (Guido Kanschat, 2014/04/09) +
    73. + +
  73. Changed: operator< for cell iterators no longer looks at + (level-)subdomain ids but only compares level() and index(). This makes the + ordering inconsistent between processes on a + parallel::distributed::Triangulation, but fixes the problem that the + ordering of cells changes under mesh refinement or other causes for changing + the subdomain id. +
    + (Timo Heister, 2014/04/08) +
    74. + +
  74. New: GridTools::laplace_transform() now takes an additional, optional + parameter that indicates the "stiffness" of the mapping. +
    + (Denis Davydov, Jean-Paul Pelteret, 2014/04/07) +
    75. + +
  75. Fixed: DoFTools::extract_constant_modes now correctly identifies both + constant modes in the scalar element FE_Q_DG0, which has been realized by a + few modifications in how the constant modes propagate from the element to + the extract_constant_modes() function. +
    + (Martin Kronbichler, 2014/04/04) +
    76. + +
  76. Fixed: GridTools::laplace_transform had previously announced in + the documentation that one can also set the location of interior points, + but this was not in fact what was implemented. This has now been fixed: + the code can now do that. +
    + (Denis Davydov, Wolfgang Bangerth, 2014/03/23) +
    77. + +
  77. Improved: Inhomogeneous tangential and normal flow constraints can + now be treated via VectorTools::compute_nonzero_normal_flux_constraints + and VectorTools::compute_nonzero_tangential_flux_constraints. +
    + (Daniel Arndt, 2014/03/16) +
    78. + +
  78. Changed: Class TriaAccessor had a function parent_index(), but this function + could only work for cell accessors. The function has consequently been moved + to class CellAccessor. +
    + (Wolfgang Bangerth, 2014/03/15) +
    79. + +
  79. Fixed: step-32 had a piece of code where we accessed an internal + representation of how Trilinos vectors are actually stored. This is poor + style and has been rewritten. +
    + (Wolfgang Bangerth, 2014/03/14) +
    80. + +
  80. Fixed: VectorTools::project_boundary_values_curl_conforming contained + a bug for some cases. This is now fixed. +
    + (Markus Bürg, 2014/03/10) +
    81. + +
  81. Fixed: ParameterHandler will no longer output an error if the file + to be read ends with "end" without a newline. +
    + (Timo Heister, 2014/02/28) +
    82. + +
  82. Improved: DoFRenumbering::Cuthill_McKee can now run with distributed + triangulations with the renumbering only done within each processor's + subdomain. +
    + (Martin Kronbichler, 2014/02/20) + +
  83. Fixed: There was an indexing error in GridIn::read_vtk() that triggered + for some input files. This is now fixed. +
    + (Mayank Sabharwal, 2014/02/19) + +
  84. New: There is a new namespace TimeStepping for the algorithms that do time + integrations. In this new namespace, several Runge-Kutta methods have been + implemented: explicit methods, implicit methods, and embedded explicit methods. +
    + (Damien Lebrun-Grandie, Bruno Turcksin, 2014/02/17) + +
  85. New: There is now a class FEEvaluationDGP that implements matrix-free + evaluation routines by truncated tensor products for FE_DGP elements. +
    + (Martin Kronbichler, 2014/02/17) + +
  86. Changed: The InverseMatrixRichardson used to eat all exceptions + that may have been produced by the underlying Richardson solver, leaving + no trace that the underlying solver may have failed when you call functions + such as InverseMatrixRichardson::vmult(). These exceptions are now propagated + out to the caller. +
    + (Wolfgang Bangerth, 2014/02/16) + + +
  87. New: FE_TraceQ implements finite elements on faces, which + correspond to the traces of H1-conforming elements. +
    + (Angela Klewinghaus, 2014/02/14) + +
  88. New: FE_FaceQ and FE_FaceP now also work in 1D (with a single dof + on each vertex). +
    + (Martin Kronbichler, 2014/02/11) + +
  89. Fixed: FE_DGQ::has_support_on_face returned a wrong number for element + degree larger than 1 in 1D. This is now fixed. +
    + (Martin Kronbichler, 2014/02/10) + +
  90. Changed: DerivativeApproximation used to be a class that only had + static members. It is now a namespace. +
    + (Wolfgang Bangerth, 2014/02/08) + +
  91. New: Threads::ThreadLocalStorage::clear() clears out all objects allocated on the + current and all other threads. +
    + (Wolfgang Bangerth, 2014/02/06) + +
  92. Fixed: A configuration error on Debian Testing where accidentally a + non-pic libSuiteSparse_config.a was picked up when building a shared + library up resulting in a link error. +
    + (Matthias Maier, 2014/02/04) + +
  93. Changed: GridTools::transform() can now deal with meshes with hanging nodes. +
    + (Timo Heister, 2014/02/04) +
    94. + +
  94. Fixed: Calling FEValuesViews::Vector::get_function_curls() computed + wrong results in some cases (see https://code.google.com/p/dealii/issues/detail?id=182). + This is now fixed. +
    + (Christoph Heiniger, Wolfgang Bangerth, 2014/02/03) + +
  95. Added: The class LAPACKFullMatrix now implements interfaces to + matrix-matrix multiplication. Also, LAPACKFullMatrix::apply_lu_factorization + now also operates on multiple right hand sides in form of another + LAPACKFullMatrix. +
    + (Martin Kronbichler, 2014/02/03) + +
  96. Fixed: The build system does no longer record full paths to system + libraries but uses the appropriate short names instead. +
    + (Matthias Maier, 2014/02/01) + +
  97. Reworked: External feature setup. Disabling a feature now cleans up + associated internal, cached variables. A per-feature linkage test now spots + common linking inconsistencies early in the configuration stage (and not + just after a complete compilation). +
    + (Matthias Maier, 2014/02/01) + +
  98. New/fixed: The ParameterHandler::print_parameters_section + method did not work for XML output. There is now a flag + include_top_level_elements which prints all higher + subsection elements, default is false. + For XML output setting this flag to true is required + to ensure that the output is a valid XML document, + starting with one root element ParameterHandler and + compatible with read_input_from_xml and the parameterGUI. +
    + (Martin Steigemann, 2014/02/01) + +
  99. New: There is now a method to copy the content from a + PETScWrappers::MPI::Vector and TrilinosWrappers::MPI::Vector to + deal.II's parallel distributed vector. +
    + (Ben Thompson, Martin Kronbichler, 2014/01/31) + +
  100. Fixed: The SolutionTransfer class had all sorts of problems when + used with hp::DoFHandler that made its results at least questionable. + Several parts of this class have been rewritten to make the results + more predictable and, likely, more correct. +
    + (Wolfgang Bangerth, 2014/01/26) + +
  101. Fixed: A regression where a single whitespace accidentally added to + DEAL_II_LINKER_FLAGS internally prevented cmake-2.8.8 from configuring + successfully. +
    + (Matthias Maier, Krysztof Bzowski, 2014/01/26) + +
  102. Fixed: SparsityPattern::max_entries_per_row() forgot to consider + the last row of the matrix and consequently sometimes returned + wrong values. This is now fixed. +
    + (Martin Kronbichler, 2014/01/22) +
    103. + +
  103. Improved: In rare cases when the vector of error indicators + has entries equal to zero the adjust_interesting_range method + produces a negative lower bound. As a result the + parallel::distributed::GridRefinement::refine_and_coarsen_fixed_* + methods flagged the wrong number of cells for coarsening and refinement. + This is now changed by adjusting the lower bound in adjust_interesting_range + only, if not equal to zero. +
    + (Martin Steigemann, 2014/01/22) +
    104. + +
  104. Changed: It was previously possible to set the + active_fe_index on non-active cells of an hp::DoFHandler. + However, this was prone to mistakes because it may lead to the assumption + that a finite element space out of the ones described by the hp::FECollection + associated with this hp::DoFHandler was actually associated with such + a cell. Since we do not actually distribute degrees of freedom for such + hp::DoFHandler objects on non-active cells, this is not the case. Consequently, + it no longer has any effect to assign active FE indices to non-active cells: + these values are simply reset later on. +
    + (Wolfgang Bangerth, 2014/01/20) +
    105. + +
  105. Fixed: The method DoFTools::extract_constant_modes only worked for + elements where the constant function 1 is represented by all ones. This + is now fixed by querying the element for its constant modes on each cell. +
    + (Martin Kronbichler, 2014/01/19) +
    106. + +
  106. Fixed: PETScWrappers::MPI::Vector::all_zero() was broken with more than + one processor (illegal memory access) and did not communicate between all + processors. Documentation for many vector types of all_zero() has been extended. +
    + (Timo Heister, 2014/01/17) +
    107. + +
  107. Fixed/new: DoFCellAccessor::set_dof_values_by_interpolation and + DoFCellAccessor::get_interpolated_dof_values could previously be + called for hp::DoFHandler objects on cells that are non-active. This + makes no sense since these cells have no associated finite element + space. Doing so now raises an exception. +
    + However, there are legitimate cases where one may want to interpolate + from children to a parent's finite element space or the other way around. + Since in the hp + case no finite element space is naturally associated with an inactive + cell, it is now possible to pass an explicit finite element index + argument to these functions specifying which element of an hp::FECollection + object describes the space onto which you want to interpolate. +
    + (Mihai Alexe, Wolfgang Bangerth, 2014/01/18) +
    108. + +
  108. Fixed: The methods IndexSet::do_compress() and + IndexSet::add_indices(IndexSet&) had quadratic complexity in the number of + ranges. The algorithms have been changed into linear complexity ones. +
    + (Martin Kronbichler, 2014/01/15) +
    109. + +
  109. Fixed: There were several bugs in functions like + FEValues::get_function_values() where the code did not properly handle the + case of FE_Nothing. This is now fixed. +
    + (Wolfgang Bangerth, 2014/01/08) +
    110. + +
  110. Fixed: DataOut got confused in some situations where one uses FE_Nothing. + This is now fixed. +
    + (Minh Do-Quang, Wolfgang Bangerth, 2014/01/08) +
    111. + +
  111. Fixed: FESystem::get_interpolation_matrix, a function that is among + other places used by SolutionTransfer, had a bug that prevented it from + running correctly in some situations where one uses FE_Nothing. + This is now fixed. +
    + (Minh Do-Quang, Wolfgang Bangerth, 2014/01/08) +
    112. + +
  112. Improved: When you call WorkStream::run with an empty function object + for the copier, operations on individual cells are essentially all independent. + In other words, you have a massively parallel collection of jobs. In this + case, a parallel for loop over all elements is better suited than the + pipeline approach currently used. This has now been implemented. +
    + (Wolfgang Bangerth, 2013/12/26) +
    113. + +
  113. New: The new function VectorTools::interpolate_based_on_material_id() + can be used to interpolate several functions onto a mesh, based on the + material id of each cell individually. +
    + (Valentin Zingan, 2013/12/26) +
    114. + +
  114. New: A new reinit() method has been introduced to + TrilinosWrappers::SparsityPattern that takes all rows that are possibly + written into as an optional argument. This allows for pre-allocating all + possible entries right away, which makes writing into the matrix from + several threads possible (otherwise, only one processor at a time can write + off-processor data). Similarly, TrilinosWrappers::MPI::Vector objects can + be initialized with hints to ghost elements for a writable vector that can + be added into from multiple threads. +
    + (Martin Kronbichler, 2013/12/23) +
    115. + +
  115. New: The TableBase::fill function has become more powerful in that + it now doesn't just take pointers to initializing elements but can deal + with arbitrary input iterators. It now also takes a flag that denotes the + order in which table elements are initialized, allowing to switch between + C- and Fortran-style table layouts. +
    + Along with the TableBase::fill function, the Table classes of various + ranks have also gotten constructors that allow the in-place construction + not only of a table of correct size, but already initialized from + somewhere. This finally allows to mark Table objects as const by creating + them already with the correct content. +
    + (Wolfgang Bangerth, 2013/12/21) +
    116. + +
  116. New: There is now a new class Functions::InterpolatedTensorProductGridData that can + be used to (bi-/tri-)linearly interpolate data given on a tensor product + mesh of $x$ (and $y$ and $z$) values, for example to evaluate experimentally + determined coefficients, or to assess the accuracy of a solution by + comparing with a solution generated by a different code and written in + gridded data. There is also a new class Functions::InterpolatedUniformGridData that + can perform the same task more efficiently if the data is stored on meshes + that are uniform in each coordinate direction. +
    + (Wolfgang Bangerth, 2013/12/20) +
    117. + +
  117. Fixed: ParameterHandler::get_double() and ParameterHandler::get_integer() + had bugs in that they didn't detect if they were asked to return a number + for a parameter whose value was in fact not a number but some general + text. This is now fixed. +
    + (Wolfgang Bangerth, 2013/12/19) +
    118. + +
  118. Fixed: VectorTools::project_boundary_values could not deal with + function values close to (but not exactly equal to) zero. This is now fixed. +
    + (Martin Kronbichler, 2013/12/16) +
    119. + +
  119. New: It is now possible to select between different smoothers and coarse + solvers in the Trilinos AMG preconditioners by a string to the smoother's name. +

  1. Removed: The base class to the iterative linear solvers, Solver, - received a SolverControl object upon construction and had a member - function control() that returned a reference to the - object previously passed in.

  2.

If there were multiple MPI processes on a - given node, this would lead to (sometimes massive) overallocation of resources - because every MPI process would create as many threads as there are cores. - This has now been changed: an argument equal to numbers::invalid_unsigned_int - is now interpreted as "subdivide the available cores between all MPI - processes running on the current system and let each process create as many - threads as cores were allocated to it". -

  6. Changed: The various classes generating graphical output, such - as DataOut or DataOutStack, are all derived from a common interface - class DataOutInterface which, in turn was derived from DataOutBase - through private inheritance. Because we frequently also - access the (public) members of this private base class this has tripped - up most every compiler we know of at one point or another. Furthermore, - because DataOutBase was a class that only defined static member functions - and had not member variables, there was really no reason for this - construct. -
    - For these reasons, DataOutBase is now just a regular namespace and the - inheritance is gone. For the most part, this should not lead to any - incompatibilities except in cases where you accessed members of - DataOutBase through their derived classes. For example, it was possible - to write DataOut::Patch even though the - Patch class is actually declared in DataOutBase. Since - the inheritance is now gone, this is no longer possible and one - actually has to write DataOutBase::Patch instead. Using this form - turns out to be compatible also with older versions of deal.II. -

  14. New: Added support for curved interior cells for all Triangulation - dimensions. -
    - A new Manifold class was introduced which only contains the - interface needed by Triangulation to refine objects, leaving all boundary - related functions in the class Boundary, which was made - derived from Manifold. -
    - This new construction allows for curved interior cells, and custom refinement - strategies (see, for example, the new tutorial program step-53). - At the moment the following Manifolds are supported: -
      -
    • FlatManifold: This class replaces the old - StraightBoundary, and it adds support for periodic - manifolds. This is the simplest class one can use to create new Manifold classes; -
      • -
    • ManifoldChart: This is one of the most general Manifold - one can think of. The user can overload the functions ManifoldChart::pull_back() and - ManifoldChart::push_forward(), to obtain a very general curved geometry, following - concepts typical of elasticity; -
      • -
    • SphericalManifold: A simple implementation of spherical coordinates - transformations. This manifold allows hyper shells with curved interior cells which - follow the natural shape of the shell; -
      • -
    -
    - The functions - Triangulation::set_boundary() and Triangulation::get_boundary() can still be used to - set and get Boundary objects instead of Manifold ones. For the get function, an exception - is thrown if a conversion to a valid Boundary class cannot be made on the fly. -

  16. New: Added support for curved interior boundaries, and general - manifold id description. -
    - A new attribute was added to each triangulation object - (types::manifold_id) which allows one to specify a manifold - description, much in the same way we do for boundaries, also for - interior edges and faces. At the moment this information is used - only for objects of topological dimension less than spacedim, but a - generalization of the class Boundary is on its way to - allow also curved cells. -
    - For the moment, full backward compatibility is granted, and one can - keep using the old Boundary, together with - Triangulation::set_boundary(), and Triangulation::get_boundary() - methods. However, this change suggests to use the types::boundary_id associated - with each boundary face to indicate only boundary condition types, and - it allows to separate the geometric meaning from the physical meaning. The - suggested usage is - - types::boundary_id is used for the physical meaning - - types::manifold_id is used for the geometric meaning. -

However, this made no sense: Since degrees of - freedoms only exist on active cells - for hp::DoFHandler (i.e., there is currently no implementation - of multilevel hp::DoFHandler objects), it does not make sense - to assign active FE indices to non-active cells since they - do not have finite element spaces associated with them without - having any degrees of freedom. -
    - The same of course is true for asking for the finite element active - on a non-active cell, i.e. using the functions - DoFAccessor::active_fe_index() and - DoFAccessor::get_fe(). All of these functions now produce exceptions on - non-active cells. -

If the two space dimensions - are equal, then this function will copy the triangulation - removing all levels, e.g., flattening it.

Therefore, all the functionality has been merged - into FEEvaluation and one should only use FEEvaluation, while the other - interfaces have been marked deprecated and will be removed in a future - version.

  60. Fixed: The MatrixTools::apply_boundary_values() variant that works - on PETSc matrices could produce a deadlock in parallel if one processor - had no boundary values to apply. This is now fixed. -
    - (Michal Wichrowski, 2014/05/19) -
    61. - -
  61. New: AnyData::try_read() is a function that allows users to check - whether an entry exists and get a pointer to it without throwing an - exception in case of failure. -
    - (Guido Kanschat, 2014/05/16) -
    62. - -
  62. New: The GMRES solver of deal.II can now write an estimate of - eigenvalues to the log file, in analogy to the CG solver. This is enabled - by the flag SolverGMRES::AdditionalData::compute_eigenvalues. -
    - (Martin Kronbichler, 2014/05/11) -
    63. - -
  63. New: The GridIn::read_vtk() function places fewer restrictions - on the VTK files it wants to read and should, consequently, be able - to read more correctly formatted VTK files than before. -
    - (Giorgos Kourakos, 2014/05/08) -
    64. - -
  64. New: There is now a QSorted quadrature which takes an - arbitrary quadrature at construction time and reorders the quadrature - points according to the weights, from smaller to bigger. This should - improve stability of higher order polynomial integration. -
    - (Luca Heltai, 2014/05/07) -
    65. - -
  65. New: The class VectorizedArray now provides methods - VectorizedArray::load(ptr) to read from arbitrary pointer addresses and - VectorizedArray::store(ptr) to write to arbitrary pointer addresses, - as opposed to the data layout of VectorizedArray that requires pointers - to be aligned by the size of the array in bytes. This also circumvents - a (rare) compiler optimization bug with gcc-4.6 on SSE code in combination - with function calls, e.g. to std::sin. -
    - (Martin Kronbichler, 2014/05/05) -
    66. - -
  66. Changed: Namespace SparsityTools had a local typedef size_type - that was set equal to types::global_dof_index. This typedef has been removed - and we now use SparsityPattern::size_type wherever applicable as this is the - type we really want to use. (The code worked previously because - types::global_dof_index and SparsityPattern::size_type happen to be the same - as far as the underlying type is concerned; however, they are different - semantically.) -
    - (Wolfgang Bangerth, 2014/05/04) -
    67. - -
  67. Updated: The step-16 tutorial program was updated to the new layout - multigrid objects and thus avoids using deprecated interfaces. -
    - (Martin Kronbichler, 2014/05/03) -
    68. - -
  68. Fixed: FE_DGQArbitraryNodes::has_support_on_face was broken when - polynomials with support points not on the element boundary were used. - This is now fixed. -
    - (Martin Kronbichler, 2014/04/30) -
    69. - -
  69. Fixed: parallel::distributed::Triangulation::load now has an - additional parameter autopartition to control p4est's behavior of - rebalancing triangulations between MPI nodes upon reading. It is - particularly useful to disable this behavior when data is stored - separately (examples for this are in the regression tests mpi/p4est_save_0?). -
    - (Alexander Grayver, Matthias Maier, 2014/04/26) -
    70. - -
  70. Fixed: GridTools::find_active_cell_around_point() could get into an infinite - loop if the point we are looking for is in fact not within the domain. This is now - fixed. -
    - (Giorgos Kourakos, Timo Heister, Wolfgang Bangerth, 2014/04/14) -
    71. - -
  71. Changed: TableBase now uses AlignedVector for storing data - instead of std::vector, which allows its use for VectorizedArray - data fields which require more alignment. -
    - (Martin Kronbichler, 2014/04/09) -
    72. - -
  72. Improved: Piola transformation for FE_BDM is now active. -
    - (Guido Kanschat, 2014/04/09) -
    73. - -
  73. Changed: operator< for cell iterators no longer looks at - (level-)subdomain ids but only compares level() and index(). This makes the - ordering inconsistent between processes on a - parallel::distributed::Triangulation, but fixes the problem that the - ordering of cells changes under mesh refinement or other causes for changing - the subdomain id. -
    - (Timo Heister, 2014/04/08) -
    74. - -
  74. New: GridTools::laplace_transform() now takes an additional, optional - parameter that indicates the "stiffness" of the mapping. -
    - (Denis Davydov, Jean-Paul Pelteret, 2014/04/07) -
    75. - -
  75. Fixed: DoFTools::extract_constant_modes now correctly identifies both - constant modes in the scalar element FE_Q_DG0, which has been realized by a - few modifications in how the constant modes propagate from the element to - the extract_constant_modes() function. -
    - (Martin Kronbichler, 2014/04/04) -
    76. - -
  76. Fixed: GridTools::laplace_transform had previously announced in - the documentation that one can also set the location of interior points, - but this was not in fact what was implemented. This has now been fixed: - the code can now do that. -
    - (Denis Davydov, Wolfgang Bangerth, 2014/03/23) -
    77. - -
  77. Improved: Inhomogeneous tangential and normal flow constraints can - now be treated via VectorTools::compute_nonzero_normal_flux_constraints - and VectorTools::compute_nonzero_tangential_flux_constraints. -
    - (Daniel Arndt, 2014/03/16) -
    78. - -
  78. Changed: Class TriaAccessor had a function parent_index(), but this function - could only work for cell accessors. The function has consequently been moved - to class CellAccessor. -
    - (Wolfgang Bangerth, 2014/03/15) -
    79. - -
  79. Fixed: step-32 had a piece of code where we accessed an internal - representation of how Trilinos vectors are actually stored. This is poor - style and has been rewritten. -
    - (Wolfgang Bangerth, 2014/03/14) -
    80. - -
  80. Fixed: VectorTools::project_boundary_values_curl_conforming contained - a bug for some cases. This is now fixed. -
    - (Markus Bürg, 2014/03/10) -
    81. - -
  81. Fixed: ParameterHandler will no longer output an error if the file - to be read ends with "end" without a newline. -
    - (Timo Heister, 2014/02/28) -
    82. - -
  82. Improved: DoFRenumbering::Cuthill_McKee can now run with distributed - triangulations with the renumbering only done within each processor's - subdomain. -
    - (Martin Kronbichler, 2014/02/20) - -
  83. Fixed: There was an indexing error in GridIn::read_vtk() that triggered - for some input files. This is now fixed. -
    - (Mayank Sabharwal, 2014/02/19) - -
  84. New: There is a new namespace TimeStepping for the algorithms that do time - integrations. In this new namespace, several Runge-Kutta methods have been - implemented: explicit methods, implicit methods, and embedded explicit methods. -
    - (Damien Lebrun-Grandie, Bruno Turcksin, 2014/02/17) - -
  85. New: There is now a class FEEvaluationDGP that implements matrix-free - evaluation routines by truncated tensor products for FE_DGP elements. -
    - (Martin Kronbichler, 2014/02/17) - -
  86. Changed: The InverseMatrixRichardson used to eat all exceptions - that may have been produced by the underlying Richardson solver, leaving - no trace that the underlying solver may have failed when you call functions - such as InverseMatrixRichardson::vmult(). These exceptions are now propagated - out to the caller. -
    - (Wolfgang Bangerth, 2014/02/16) - - -
  87. New: FE_TraceQ implements finite elements on faces, which - correspond to the traces of H1-conforming elements. -
    - (Angela Klewinghaus, 2014/02/14) - -
  88. New: FE_FaceQ and FE_FaceP now also work in 1D (with a single dof - on each vertex). -
    - (Martin Kronbichler, 2014/02/11) - -
  89. Fixed: FE_DGQ::has_support_on_face returned a wrong number for element - degree larger than 1 in 1D. This is now fixed. -
    - (Martin Kronbichler, 2014/02/10) - -
  90. Changed: DerivativeApproximation used to be a class that only had - static members. It is now a namespace. -
    - (Wolfgang Bangerth, 2014/02/08) - -
  91. New: Threads::ThreadLocalStorage::clear() clears out all objects allocated on the - current and all other threads. -
    - (Wolfgang Bangerth, 2014/02/06) - -
  92. Fixed: A configuration error on Debian Testing where accidentally a - non-pic libSuiteSparse_config.a was picked up when building a shared - library up resulting in a link error. -
    - (Matthias Maier, 2014/02/04) - -
  93. Changed: GridTools::transform() can now deal with meshes with hanging nodes. -
    - (Timo Heister, 2014/02/04) -
    94. - -
  94. Fixed: Calling FEValuesViews::Vector::get_function_curls() computed - wrong results in some cases (see https://code.google.com/p/dealii/issues/detail?id=182). - This is now fixed. -
    - (Christoph Heiniger, Wolfgang Bangerth, 2014/02/03) - -
  95. Added: The class LAPACKFullMatrix now implements interfaces to - matrix-matrix multiplication. Also, LAPACKFullMatrix::apply_lu_factorization - now also operates on multiple right hand sides in form of another - LAPACKFullMatrix. -
    - (Martin Kronbichler, 2014/02/03) - -
  96. Fixed: The build system does no longer record full paths to system - libraries but uses the appropriate short names instead. -
    - (Matthias Maier, 2014/02/01) - -
  97. Reworked: External feature setup. Disabling a feature now cleans up - associated internal, cached variables. A per-feature linkage test now spots - common linking inconsistencies early in the configuration stage (and not - just after a complete compilation). -
    - (Matthias Maier, 2014/02/01) - -
  98. New/fixed: The ParameterHandler::print_parameters_section - method did not work for XML output. There is now a flag - include_top_level_elements which prints all higher - subsection elements, default is false. - For XML output setting this flag to true is required - to ensure that the output is a valid XML document, - starting with one root element ParameterHandler and - compatible with read_input_from_xml and the parameterGUI. -
    - (Martin Steigemann, 2014/02/01) - -
  99. New: There is now a method to copy the content from a - PETScWrappers::MPI::Vector and TrilinosWrappers::MPI::Vector to - deal.II's parallel distributed vector. -
    - (Ben Thompson, Martin Kronbichler, 2014/01/31) - -
  100. Fixed: The SolutionTransfer class had all sorts of problems when - used with hp::DoFHandler that made its results at least questionable. - Several parts of this class have been rewritten to make the results - more predictable and, likely, more correct. -
    - (Wolfgang Bangerth, 2014/01/26) - -
  101. Fixed: A regression where a single whitespace accidentally added to - DEAL_II_LINKER_FLAGS internally prevented cmake-2.8.8 from configuring - successfully. -
    - (Matthias Maier, Krysztof Bzowski, 2014/01/26) - -
  102. Fixed: SparsityPattern::max_entries_per_row() forgot to consider - the last row of the matrix and consequently sometimes returned - wrong values. This is now fixed. -
    - (Martin Kronbichler, 2014/01/22) -
    103. - -
  103. Improved: In rare cases when the vector of error indicators - has entries equal to zero the adjust_interesting_range method - produces a negative lower bound. As a result the - parallel::distributed::GridRefinement::refine_and_coarsen_fixed_* - methods flagged the wrong number of cells for coarsening and refinement. - This is now changed by adjusting the lower bound in adjust_interesting_range - only, if not equal to zero. -
    - (Martin Steigemann, 2014/01/22) -
    104. - -
  104. Changed: It was previously possible to set the - active_fe_index on non-active cells of an hp::DoFHandler. - However, this was prone to mistakes because it may lead to the assumption - that a finite element space out of the ones described by the hp::FECollection - associated with this hp::DoFHandler was actually associated with such - a cell. Since we do not actually distribute degrees of freedom for such - hp::DoFHandler objects on non-active cells, this is not the case. Consequently, - it no longer has any effect to assign active FE indices to non-active cells: - these values are simply reset later on. -
    - (Wolfgang Bangerth, 2014/01/20) -
    105. - -
  105. Fixed: The method DoFTools::extract_constant_modes only worked for - elements where the constant function 1 is represented by all ones. This - is now fixed by querying the element for its constant modes on each cell. -
    - (Martin Kronbichler, 2014/01/19) -
    106. - -
  106. Fixed: PETScWrappers::MPI::Vector::all_zero() was broken with more than - one processor (illegal memory access) and did not communicate between all - processors. Documentation for many vector types of all_zero() has been extended. -
    - (Timo Heister, 2014/01/17) -
    107. - -
  107. Fixed/new: DoFCellAccessor::set_dof_values_by_interpolation and - DoFCellAccessor::get_interpolated_dof_values could previously be - called for hp::DoFHandler objects on cells that are non-active. This - makes no sense since these cells have no associated finite element - space. Doing so now raises an exception. -
    - However, there are legitimate cases where one may want to interpolate - from children to a parent's finite element space or the other way around. - Since in the hp - case no finite element space is naturally associated with an inactive - cell, it is now possible to pass an explicit finite element index - argument to these functions specifying which element of an hp::FECollection - object describes the space onto which you want to interpolate. -
    - (Mihai Alexe, Wolfgang Bangerth, 2014/01/18) -
    108. - -
  108. Fixed: The methods IndexSet::do_compress() and - IndexSet::add_indices(IndexSet&) had quadratic complexity in the number of - ranges. The algorithms have been changed into linear complexity ones. -
    - (Martin Kronbichler, 2014/01/15) -
    109. - -
  109. Fixed: There were several bugs in functions like - FEValues::get_function_values() where the code did not properly handle the - case of FE_Nothing. This is now fixed. -
    - (Wolfgang Bangerth, 2014/01/08) -
    110. - -
  110. Fixed: DataOut got confused in some situations where one uses FE_Nothing. - This is now fixed. -
    - (Minh Do-Quang, Wolfgang Bangerth, 2014/01/08) -
    111. - -
  111. Fixed: FESystem::get_interpolation_matrix, a function that is among - other places used by SolutionTransfer, had a bug that prevented it from - running correctly in some situations where one uses FE_Nothing. - This is now fixed. -
    - (Minh Do-Quang, Wolfgang Bangerth, 2014/01/08) -
    112. - -
  112. Improved: When you call WorkStream::run with an empty function object - for the copier, operations on individual cells are essentially all independent. - In other words, you have a massively parallel collection of jobs. In this - case, a parallel for loop over all elements is better suited than the - pipeline approach currently used. This has now been implemented. -
    - (Wolfgang Bangerth, 2013/12/26) -
    113. - -
  113. New: The new function VectorTools::interpolate_based_on_material_id() - can be used to interpolate several functions onto a mesh, based on the - material id of each cell individually. -
    - (Valentin Zingan, 2013/12/26) -
    114. - -
  114. New: A new reinit() method has been introduced to - TrilinosWrappers::SparsityPattern that takes all rows that are possibly - written into as an optional argument. This allows for pre-allocating all - possible entries right away, which makes writing into the matrix from - several threads possible (otherwise, only one processor at a time can write - off-processor data). Similarly, TrilinosWrappers::MPI::Vector objects can - be initialized with hints to ghost elements for a writable vector that can - be added into from multiple threads. -
    - (Martin Kronbichler, 2013/12/23) -
    115. - -
  115. New: The TableBase::fill function has become more powerful in that - it now doesn't just take pointers to initializing elements but can deal - with arbitrary input iterators. It now also takes a flag that denotes the - order in which table elements are initialized, allowing to switch between - C- and Fortran-style table layouts. -
    - Along with the TableBase::fill function, the Table classes of various - ranks have also gotten constructors that allow the in-place construction - not only of a table of correct size, but already initialized from - somewhere. This finally allows to mark Table objects as const by creating - them already with the correct content. -
    - (Wolfgang Bangerth, 2013/12/21) -
    116. - -
  116. New: There is now a new class Functions::InterpolatedTensorProductGridData that can - be used to (bi-/tri-)linearly interpolate data given on a tensor product - mesh of $x$ (and $y$ and $z$) values, for example to evaluate experimentally - determined coefficients, or to assess the accuracy of a solution by - comparing with a solution generated by a different code and written in - gridded data. There is also a new class Functions::InterpolatedUniformGridData that - can perform the same task more efficiently if the data is stored on meshes - that are uniform in each coordinate direction. -
    - (Wolfgang Bangerth, 2013/12/20) -
    117. - -
  117. Fixed: ParameterHandler::get_double() and ParameterHandler::get_integer() - had bugs in that they didn't detect if they were asked to return a number - for a parameter whose value was in fact not a number but some general - text. This is now fixed. -
    - (Wolfgang Bangerth, 2013/12/19) -
    118. - -
  118. Fixed: VectorTools::project_boundary_values could not deal with - function values close to (but not exactly equal to) zero. This is now fixed. -
    - (Martin Kronbichler, 2013/12/16) -
    119. - -
  119. New: It is now possible to select between different smoothers and coarse - solvers in the Trilinos AMG preconditioners by a string to the smoother's name. -
