+This is the list of changes made between the release of +deal.II version 7.3.0 and that of 8.0.0. +All entries are signed with the names of the authors. +

+ + + + + + +

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: it was possible to call get_dof_indices(), get_dof_values(), +set_dof_values(), and distribute_local_to_global() for cells that were not +active, if the finite element only had DoFs on vertices (i.e. Q1). This is +no longer allowed. +
    +(Timo Heister, 2013/06/02) + +
  2. Changed: Internal structures of ExceptionBase are now thread safe. The +Assert macro does not print an exception to deallog any more prior to +throwing if deal_II_exceptions::abort_on_exception==false. Removed: A +number of obsolete Exceptions that are not used in the library any more. +
    +(Matthias Maier, 2013/04/16) + +
  3. Removed: A number of header files that have been deprecated a long time +ago have been removed. All of them had previously only included the header file +that had superseded them. To upgrade, simply include the currently used +header file. This is also backward compatible with deal.II 7.3. +
    +(Guido Kanschat, 2013/04/12) + +
  4. Removed: The interfaces to the obsolete direct solvers MA27 and MA47 from +the Harwell Subroutine Library. Support for the HSL routines were not ported to +the new build system. However, the sparse direct solver UMFPACK remains to be +supported and is provided as part of the standard deal.II distribution, unlike +the HSL functions. +
    +(Matthias Maier, 2013/04/01) + +
  5. Changed: The TimeDependent::end_sweep function with an argument indicating +the number of threads has been removed. Use the corresponding function without +an argument. Since the argument had a default value, few users will have used +this function. +
    +(Wolfgang Bangerth, 2013/03/17) + +
+ + + + + +

General

+ + +
    +
  1. Improvements on the CMake build system: A Working C (or Fortran) compiler + is now fully optional; Improved support for static linkage with a toggle + "DEAL_II_PREFER_STATIC_LIBS" that will prefer static archives for non system + libraries and "DEAL_II_STATIC_EXECUTABLE" that will switch the complete link + interface to static linkage. +
    + (Matthias Maier, 2013/07/16) +
    2. + +
  2. New: various functions for parallel computations got introduced to + make Trilinos and PETSc interfaces similar. Now step-40 can be used with + PETSc or Trilinos with just a few changes. This patch also introduces + better support for block systems in the PETSc interfaces. +
    + (Timo Heister, 2013/07/15) +
    3. + +
  3. New: deal.II can now be compiled to 64-bit global dof indices. To turn + this feature on, use the cmake option -DDEAL_II_WITH_64BIT_INDICES=ON. If + PETSc and/or Trilinos are used, they must be compiled to support 64-bit + indices. To write a code that can use 32-bit and 64-bit indices depending on + deal.II compilation option, use types::global_dof_index for all the global + dof indices. +
    + (Kainan Wang and Bruno Turcksin, 2013/06/05) +
    4. + +
  4. New: All vector classes now have a member function + locally_owned_elements that returns an index + set indicating which elements of this vector the current + processor owns. +
    + (Wolfgang Bangerth, 2013/05/24) +
    5. + + +
  5. New: A new element FE_Q_iso_Q1 has been implemented that is defined by + a subdivision of the element into smaller Q1 elements. An element of order + @p p is similar to FE_Q of degree @p p with the same numbering of degrees of + freedom. The element is useful e.g. for defining a sparser preconditioner + matrix for AMG at higher order FE_Q elements or for representing a component + of a system of PDEs where higher resolution is preferred over high order. +
    + (Martin Kronbichler, 2013/05/14) +
    6. + +
  6. New: The step-49 tutorial program now also has a discussion on + what to do once you have a coarse mesh and want to refine it. +
    + (Wolfgang Bangerth, 2013/04/03) +
    7. + +
  7. New: The number of threads used by deal.II/TBB can now be limited at + run time. Using MPI based code using PETSc/Trilinos no longer requires you + to compile the library without threads. See MPI_InitFinalize and + MultithreadInfo::set_thread_limit for details. +
    + (Timo Heister, 2013/03/26) +
    8. + +
  8. New: The results section of step-36 now explains how to use ARPACK + as an alternative to SLEPc as eigenvalue solver. +
    + (Juan Carlos Araujo Cabarcas, 2013/03/25) +
    9. + +
  9. New: deal.II now uses CMake + as its configuration and build tool. Please read through the + readme and other installation files for information about how the + installation process has changed. +
    + Because this touches the configuration of every external package we + interact with, there are a number of other changes as a result: +
      +
    • The minimum supported version for Trilinos is now 10.8.x. +
    • We no longer link with different versions of the p4est library + in debug and optimized mode. Rather, we now link with the same + library in both modes. The p4est installation instructions have + been updated. TODO TODO TODO +
    +

Specific improvements

+ +
    + +
  1. New: VectorTools::project and a whole host of similar functions +are now also available for objects of type hp::DoFHandler. +
    +(Wolfgang Bangerth, 2013/07/21) +
    2. + +
  2. Fixed: hp::DoFHandler::n_boundary_dofs() had a bug that always led +to a failed assertion. This is now fixed. +
    +(Wolfgang Bangerth, 2013/07/21) +
    3. + +
  3. Fixed: VectorTools::project has an option to first project onto the +boundary. However, the implementation of this option ignored the mapping +that is provided to the function. This is now fixed. +
    +(Wolfgang Bangerth, 2013/07/16) +
    4. + +
  4. Improved: The WorkStream class used throughout deal.II is now using +thread local variables and initializes temporary variables on the thread +that uses them, leading to better cache locality. +
    +(Wolfgang Bangerth, 2013/07/16) +
    5. + +
  5. Improved: The "pure" functions in MeshWorker::LocalIntegrator are now implemented and throw +an exception if not overloaded. +
    +(Guido Kanschat, 2013/07/16) +
    6. + +
  6. New: The function SparseDirectUMFPACK::Tvmult is now implemented. +
    +(Matthias Maier, 2013/07/03) +
    7. + +
  7. New: In addition to the FEValuesExtractors::Scalar, +FEValuesExtractors::Vector, and FEValuesExtractors::SymmetricTensor classes, +there are now also fully featured FEValuesExtractors::Tensor extractors +for non-symmetric tensors of rank 2. +
    +(Denis Davydov, 2013/07/02) +
    8. + +
  8. New: There are now functions Tensor::component_to_unrolled_index() +and Tensor::unrolled_to_component_indices() in the same way as they +already exist for the SymmetricTensor class. +
    +(Denis Davydov, 2013/07/02) +
    9. + +
  9. New: There is now a read-write version of TableIndices::operator[]. +
    +(Denis Davydov, 2013/07/02) +
    10. + +
  10. New: The function parallel::distributed::Triangulation::copy_triangulation() is +now implemented. +
    +(Martin Steigemann, 2013/07/02) +
    11. + +
  11. New: TriaRawIterator::operator < (TriaRawIterator&) now implements a total ordering +relation for cells even on distributed::parallel::Triangulation across processors. +Additionally, TriaRawAccessor and CellAccessor now have an ordering relation. +
    +(Guido Kanschat, 2013/06/24) +
    12. + +
  12. New: CellAccessor::id() that returns a unique CellId that +also works in parallel computations (where level and index is not +useful). +
    +(Timo Heister, 2013/06/24) +
    13. + +
  13. New: added ConstantTensorFunction and ZeroTensorFunction to provide +a tensor valued analogue to ConstantFunction and ZeroFunction. +
    +(Matthias Maier, 2013/06/20) +
    14. + +
  14. Fixed: BlockSparsityPattern::column_number was returning +wrong values. +
    +(Timo Heister, 2013/06/16) +
    15. + +
  15. Fixed: The stabilization parameter for the artificial diffusion +in the step-31 tutorial program has been increased slightly to avoid +instabilities at later times (t > 60). +
    +(Martin Kronbichler, 2013/06/04) +
    16. + +
  16. Fixed: If an exception was generated on a task created by +Threads::new_task, the program would terminate with a segmentation +fault, leaving little trace of what had happened. This is now handled +more gracefully. +
    +(Wolfgang Bangerth, 2013/06/02) +
    17. + +
  17. Changed: subdomain ids can now only be queried/set on active cells. +Consequently, is_artificial(), is_ghost(), and is_locally_owned() is +now restricted to active cells. +
    +(Timo Heister, 2013/05/31) +
    18. + +
  18. Improved: Triangulation::begin(level) and Triangulation::end(level) now return an +empty iterator range if the level is larger than the maximal locally owned level, +but still in the global level range of a distributed Triangulation. +
    +(Timo Heister and Guido Kanschat, 2013/05/26) +
    19. + +
  19. New: The IndexSet::add_indices function that takes another IndexSet +object now has an additional argument offset that can be used +to offset the indices of first argument. +
    +(Wolfgang Bangerth, 2013/05/25) +
    20. + +
  20. New: ConstraintMatrix::distribute is now also implemented for +arguments of type PETScWrappers::MPI::BlockVector. +
    +(Wolfgang Bangerth, 2013/05/25) +
    21. + +
  21. Fixed: IndexSet::operator== returned the wrong results +in some cases. +
    +(Wolfgang Bangerth, 2013/05/25) +
    22. + +
  22. New: The global function complete_index_set() +creates and returns an index set of given size that contains +every single index with this range. +
    +(Wolfgang Bangerth, 2013/05/24) +
    23. + +
  23. New: All vector classes now have a static member variable +supports_distributed_data that indicates whether the +vector class supports data that is distributed across multiple +processors. This variable is provided as a traits variable +to allow generic algorithms working on general vector types to +query the capabilities of the vector class at compile time. +
    +(Wolfgang Bangerth, 2013/05/23) +
    24. + +
  24. Fixed: FETools::back_interpolate has been revised to work correctly +also with parallel::distributed::Vector. +
    +(Martin Steigemann, 2013/05/23) +
    25. + +
  25. Removed: The file mesh_worker/vector_info.h was unused and +untested. It has thus been removed. +
    +(Wolfgang Bangerth, Guido Kanschat, 2013/05/21) +
    26. + +
  26. Fixed: The method parallel::distributed::Vector::compress +(VectorOperation::insert) previously set the elements of ghost elements +unconditionally on the owning processor, even if they had not been touched. +This led to a problem in certain library functions where vector entries became +zero in a spurious way. This is now fixed by discarding the elements in ghost +entries for the VectorOperation::insert operation. This is legitimate since we +assume consistency of set elements across processors, so the owning processor +sets the element already. +
    +(Martin Kronbichler, 2013/05/21) +
    27. + +
  27. Improved: DoFTools::make_periodicity_constraints now also works +for meshes where the refinement level of the two sides of the domain +is not the same, i.e., one side is more refined than the other. +
    +(Wolfgang Bangerth, 2013/05/20) +
    28. + +
  28. Improved: Through the fields DataOutBase::VtkFlags::time and +DataOutBase::VtkFlags::cycle, it is now possible to encode the time and/or +cycle within a nonlinear or other iteration in VTK and VTU files written +via DataOutBase::write_vtk and DataOutBase::write_vtu. +
    +(Wolfgang Bangerth, 2013/05/12) +
    29. + +
  29. Fixed: The method ConvergenceTable::evaluate_convergence_rates with + reference column did not take the dimension of the reference column into + account, leading to wrong logarithmic rates for dim!=2. This can now be fixed + by specifying the dimension as a last argument. +
    +(Martin Kronbichler, 2013/05/10) +
    30. + +
  30. Improved: The functions MatrixTools::create_mass_matrix and +MatrixTools::create_laplace_matrix take now an optional ConstraintMatrix +argument that allows to directly apply the constraints. This also helps +VectorTools::project. Note that not providing constraints remains the default +and recommended way to ensure consistency when several matrices are combined. +
    +(Martin Kronbichler, 2013/05/08) +
    31. + +
  31. New: The classes TrilinosWrappers::SparseMatrix and +TrilinosWrappers::BlockSparseMatrix now fully implement vmult and Tvmult with +deal.II's own vector classes Vector and +parallel::distributed::Vector. +
    +(Martin Kronbichler, 2013/05/08) +
    32. + +
  32. Improved: The matrix-vector product ChunkSparseMatrix::vmult now runs in +parallel in shared memory. +
    +(Martin Kronbichler, 2013/05/07) +
    33. + +
  33. New: The class ChunkSparseMatrix and the associated +ChunkSparsityPattern now offer iterator classes to iterate over rows of the +matrix in an STL-like way. +
    +(Martin Kronbichler, 2013/05/07) +
    34. + +
  34. Fixed: The stopping criterion for early exit in SolverBicgstab did not +work properly for systems with large values, leading to premature exit. This +is now fixed. +
    +(Martin Kronbichler, 2013/05/07) +
    35. + +
  35. Changed: The SolverGMRES implementation previously applied two +iterations of the modified Gram–Schmidt algorithm for +orthogonalization. In many situations one iteration is enough. The algorithm +can now detect loss of orthogonality and enables re-orthogonalization only if +necessary. The second iteration (and, hence, old behavior) can be forced by +the flag SolverGMRES::AdditionalData::force_re_orthogonalization. +
    +(Martin Kronbichler, 2013/05/06) +
    36. + +
  36. Changed: FETools::interpolate is now instantiated for all +vector types, not just dealii::Vector and dealii::BlockVector. +
    +(Wolfgang Bangerth, 2013/05/06) +
    37. + +
  37. Fixed: setting values in TrilinosWrappers::SparseMatrix +in parallel was adding the values instead. +
    +(Bruno Turcksin, Timo Heister, 2013/05/03) +
    38. + +
  38. Fixed: Generate an error if the user tries to refine a cell +that is already on the maximum level in a distributed triangulation. +
    +(Timo Heister, 2013/05/01) +
    39. + +
  39. Fixed: The version of ParameterHandler::set that takes a boolean +as second argument was broken and did not work. This is now fixed. +
    +(Ashkan Dorostkar, Wolfgang Bangerth, 2013/04/30) +
    40. + +
  40. Fixed: PETScWrappers::VectorBase::print now saves and restores +the precision +and width associated with the stream it prints to around setting +the values passed as arguments. +
    +(Fahad Alrashed, 2013/04/22) +
    41. + +
  41. Fixed: FullMatrix::print now saves and restores the precision +and width associated with the stream it prints to around setting +the values passed as arguments. +
    +(Fahad Alrashed, 2013/04/22) +
    42. + +
  42. New: LogStream now has member functions LogStream::width, +LogStream::precision and LogStream::flags that make it look more +like normal objects of type std::ostream. +
    +(Fahad Alrashed, 2013/04/22) +
    43. + +
  43. New: SparseDirectUMFPACK has long had the ability to work with +BlockSparseMatrix objects, but couldn't deal with BlockVector objects. +This is now fixed. +
    +(Wolfgang Bangerth, 2013/04/21) +
    44. + +
  44. New: Class TimerOutput::Scope does automatic scope based enter/ +exit_section of a TimerOutput object. +
    +(Timo Heister, 2013/04/18) +
    45. + +
  45. Fixed: TimerOutput constructed with an MPI_COMM in wall_time +mode now constructs synchronized Timer objects. This gives reliable +parallel benchmark timings. +
    +(Timo Heister, 2013/04/18) +
    46. + +
  46. Improved and Fixed: LogStream (and deallog) now respect std::flush in +addition to std::endl to write out content to the console/file. +Furthermore, LogStream::push(...) and LogStream::pop() now work in a thread +safe manner. Also allow to pop() the prefix "DEAL". +
    +(Matthias Maier, 2013/04/18) +
    47. + +
  47. Fixed: The HalfHyperShellBoundary class got refining +the edges that sit at the perimeter of the circular face of the domain +wrong. This is now fixed. +
    +(Wolfgang Bangerth, Jörg Frohne, 2013/04/17) +
    48. + +
  48. New: Functions::FEFieldFunction can now deal with +parallel::distributed::Triangulation objects. +
    +(Wolfgang Bangerth, 2013/04/15) +
    49. + +
  49. New: There is now a version of SparseMatrix::copy_from that can copy +from TrilinosWrappers::SparseMatrix. +
    +(Wolfgang Bangerth, Jörg Frohne, 2013/04/15) +
    50. + +
  50. Improved: The SolverCG implementation now uses only three auxiliary +vectors, down from previously four. Also, there are some shortcuts in case +PreconditionIdentity is used that improve the solver's performance. +
    +(Martin Kronbichler, 2013/04/11) +
    51. + +
  51. Fixed: The results section of step-23 did not show the movie in release 7.3 +due to a poor HTML markup. This is now fixed. +
    +(Wolfgang Bangerth, 2013/04/10) +
    52. + +
  52. Fixed: It is now possible to use the MeshWorker framework in 1d as well. +
    +(Wolfgang Bangerth, Scott Miller, 2013/04/09) +
    53. + +
  53. Fixed: It was not possible to create a default-constructed object of +type Triangulation<1>::face_iterator. This is now fixed. +
    +(Wolfgang Bangerth, Scott Miller, 2013/04/09) +
    54. + +
  54. New: VectorTools::subtract_mean_value can now be called without a +boolean mask. The vector type is templatified and instantiated for all +non distributed vectors. +
    +(Matthias Maier, 2013/04/08) +
    55. + +
  55. Fixed: It is now possible to call ConvergenceTable::evaluate_convergence_rates +multiple times. +
    +(Matthias Maier, 2013/04/08) +
    56. + +
  56. Fixed: GridTools::distort_random (previously called Triangulation::distort_random) +had a bug where points were only ever moved in positive coordinate +directions rather than with uniform probability in either direction. The 1d +implementation also had the problem that it did not move vertices if the +cell they were on was at the boundary, even if the vertex +itself was not. All of these problems are now fixed. +
    +(Wolfgang Bangerth, 2013/04/05) +
    57. + +
  57. New: There is a class VectorFunctionFromTensorFunction that converts +between objects of type TensorFunction and Function. +
    +(Spencer Patty, 2013/4/2) +
    58. + +
  58. Fixed: The ParameterHandler class could not deal with parameters named +"value" (and a few other names). This is now fixed. +
    +(Denis Davydov, Matthias Maier, Wolfgang Bangerth, 2013/3/31) +
    59. + +
  59. Changed: TimerOutput no longer assumes that sections are not nested +when outputting percentage and total run time. +
    +(Timo Heister, 2013/3/28) +
    60. + +
  60. New: MPI_InitFinalize can also initialize PETSc/Slepc when +not compiling with MPI. This is now the preferred way to initialize +MPI/PETSc/Slepc in all cases. +
    +(Timo Heister, 2013/3/26) +
    61. + +
  61. Added/fixed: IterativeInverse::vmult() can now handle vectors +using a different number type than the matrix type. As usual, the +number types must be compatible. Addtitionally, the initial guess is +always set to zero, since starting with the incoming vector makes no +sense. +
    +(Guido Kanschat, 2013/03/21) +
    62. + +
  62. Added GridOut::write_svg() to allow for the output of +two-dimensional triangulations in two space dimensions in the SVG +format (Scalable Vector Graphics, an generic XML-based vector image +format developed and maintained by the World Wide Web Consortium W3C). +This function also provides cell coloring and cell labeling for the +visualization of basic cell properties. Pespective view is further +possible and the cell level number may be converted into altitude, +revealing the inactive cells lying below. +
    +(Christian Wülker, 2013/03/21) +
    63. + +
  63. Added TimerOutput::reset to remove the collected information so far and +added a new frequency TimerOutput::never to only output information if +triggered by print_summary(). +
    +(Timo Heister, 2013/03/20) +
    64. + +
  64. Changed: FEValuesExtractors::Scalar, FEValuesExtractors::Vector and +FEValuesExtractors::SymmetricTensor could not be default constructed, and +consequently one could not easily put them into arrays (where they would +be default constructed when changing the size, and later assigned useful +values). These classes can now be default constructed to invalid +values, but can of course not be used in any useful way. +
    +(Wolfgang Bangerth, 2013/03/15) +
    65. + +
  65. Fixed: FETools::interpolation_difference did not work with PETSc. +This is now fixed. +
