+ + + + + + +

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. Changed/fixed: Several operations on Trilinos vectors that change the +elements of these vectors were allowed accidentally for vectors that have +ghost elements. This is a source of errors because a change on one +MPI process will not show up on a different processor. Consequently, we +intended to disallow all functions that modify vectors with ghost elements +but this was not enforced for all of these functions. This is now fixed +but it may lead to errors if your code relied on the existing behavior. The +way to work around this is to only ever modify fully distributed vectors, +and then copy it into a vector with ghost elements. +
    +(Wolfgang Bangerth, 2012/08/06) + +
  2. Changed: The argument material_id of the estimate-functions of +the KellyErrorEstimator class is now of type types::material_id +with default value numbers::invalid_material_id, instead of type +unsigned int with default value numbers::invalid_unsigned_int. This +should not make a difference to most users unless you specified the +argument's default value by hand. +
    +(Wolfgang Bangerth, Christian Goll 2012/02/27) + +
  3. +The member functions Triangulation::set_boundary and +Triangulation::get_boundary now take a types::boundary_id instead of +an unsigned int as argument. This now matches the actual data type +used to store boundary indicators internally. +
    +(Wolfgang Bangerth, Christian Goll 2012/02/27) +
+ + + + + +

General

+ + +
    +
  1. +New: We now support parallel output using HDF5/xdmf. +
    +(Eric Heien, Timo Heister, 2012/08/28) + +
  2. +New: We are now compatible with Trilinos 10.4.2, 10.8.5, and 10.12.2. See the +readme for more information. +
    +(Timo Heister, 2012/08/24) + +
  3. +Changed: To make the naming of types defined in namespace types +consistent, we have renamed types::subdomain_id_t to +types::subdomain_id. The old name has been retained as a typedef +but is now deprecated. +
    +(Wolfgang Bangerth, 2012/08/22) + +
  4. +Changed: Unify the concept of compress() for all linear algebra +objects. Introduce type VectorOperation to decide between +add and insert. Implement also for serial vectors. Note: +this breaks distributed::vector::compress(bool). See +@ref GlossCompress for more information. +
    +(Timo Heister, 2012/08/13) + +
  5. +Changed: Support for the METIS 4.x has been replaced with support for +METIS 5.x. Use --with-metis=path/to/metis to configure +with METIS 5.x. +
    +(Stefano Zampini, Toby D. Young 2012/08/13) + +
  6. +Changed: numerics/vectors.h is now called numerics/vector_tools.h and +numerics/matrices.h is now called numerics/matrix_tools.h The old files are +deprecated. +
    +(Timo Heister 2012/08/09) + +
  7. +New: officially added support for clang 3.1 or newer. +
    +(Timo Heister and Wolfgang Bangerth, 2012/08/07) + +
  8. +Changed: PETSc linking now prefers to use the libpetsc.so generated +by PETSc starting from version 3.1+. This fixes the problem +of linker errors on recent gcc/ubuntu versions. +
    +(Timo Heister, 2012/08/07) + +
  9. +Fixed: On some 64-bit systems, we build deal.II with the -m64 +flag but forgot to build UMFPACK with this flag as well, leading to +linker errors. This is now fixed. +
    +(Wolfgang Bangerth, 2012/07/31) + +Fixed: The Intel compiler, when using MPI, wants that mpi.h +is included before header files like stdio.h. This can't +be ensured in general because the inclusion might be indirectly, but +we now work around the problem in other ways. +
    +(Timo Heister, Wolfgang Bangerth, Michael Thomadakis, 2012/07/26) + +
  10. +Fixed: On some systems, the p4est library we use for distributed +parallel computations installs its libraries into a lib64/ +directory instead of the usual lib/. deal.II can now deal +with this. +
    +(Wolfgang Bangerth, 2012/07/25) + +
  11. +New: step-43 is an extension of step-21 that shows efficient methods +to solve multi-phase flow. +
    +(Chih-Che Chueh, Wolfgang Bangerth, 2012/06/06) + +
  12. +New: step-15 has been replaced by a program that demonstrates the +solution of nonlinear problem (the minimal surface equation) using +Newton's method. +
    +(Sven Wetterauer, 2012/06/03) + +
  13. +New: step-48 demonstrates the solution of a nonlinear wave equation +with an explicit time stepping method. The usage of Gauss-Lobatto +elements gives diagonal mass matrices, which obviates the solution of +linear systems of equations. The nonlinear right hand side is +evaluated with the matrix-free framework. +
    +(Katharina Kormann and Martin Kronbichler, 2012/05/05) + +
  14. +New: step-37 shows how the matrix-free framework can be utilized to +efficiently solve the Poisson equation without building global +matrices. It combines fast operator evaluation with a multigrid solver +based on polynomial Chebyshev smoother. +
    +(Katharina Kormann and Martin Kronbichler, 2012/05/05) + +
  15. +New: A new matrix-free interface has been implemented. The framework +is parallelized with MPI, TBB, and explicit vectorization instructions +(new data type VectorizedArray). The class MatrixFree caches +cell-based data in an efficient way. Common operations can be +implemented using the FEEvaluation class. +
    +(Katharina Kormann and Martin Kronbichler, 2012/05/05) + +
  16. +New: step-44 demonstrates one approach to modeling large +deformations of nearly-incompressible elastic solids. The +elastic response is governed by a non-linear, hyperelastic +free-energy function. The geometrical response is also +nonlinear, i.e., the program considers finite deformations. +
    +(Andrew McBride and Jean-Paul Pelteret, 2012/04/25) + +
  17. +New: step-41 demonstrates solving the obstacle problem, +a variational inequality. +
    +(Joerg Frohne, 2012/04/22) + +
  18. +Changed: The version of BOOST we ship with deal.II has been upgraded +to 1.49.0. +
    +(Martin Kronbichler, 2012/04/07) + +
  19. +New: We have added a brief section to the step-12 tutorial programs that +compares the DG solution computed there with one that one would obtain by +using a continuous finite element. +
    +(Wolfgang Bangerth, 2012/03/25) + +
  20. +New: Added support for codimension 2, i.e. for dim-dimensional objects +embedded into spacedim=dim+2 dimensional space. +
    +(Sebastian Pauletti, 2012/03/02) + +
  21. Changed: Material and Boundary indicators have been both of the +type unsigned char. Throughout the library, we changed their datatype +to types::material_id +resp. types::boundary_id, both typedefs of unsigned +char. Internal faces are now characterized by +numbers::internal_face_boundary_id(=static_cast@(-1)) +instead of 255, so we get rid of that mysterious number in the source +code. Material_ids are also assumed to lie in the range from 0 to +numbers::invalid_material_id-1 (where numbers::invalid_material_id = +static_cast(-1)). With this change, it is now +much easier to extend the range of boundary or material ids, if +needed. +
    +(Christian Goll 2012/02/27) + +
  22. New: Functions like FEValues::get_function_values have long been +able to extract values from pretty much any vector kind given to it (e.g. +of kind Vector, BlockVector, PETScWrappers::Vector, etc). The list of +allowed "vector" types now also includes IndexSet, which is interpreted +as a vector of elements that are either zero or one, depending on whether +an index is in the IndexSet or not. +
    +As a consequence of this, the DataOut::add_data_vector functions now also +work for such types of vectors, a use demonstrated in step-41. +
    +(Wolfgang Bangerth, 2012/02/14) + +
  23. New: It has long been a nuisance that the deal.II vector classes +could only be accessed using operator() whereas the C++ +std::vector class required operator[]. This +diminished the usefulness of template code. Historically, the reason +was that the deal.II vector classes should use the same operator as +the matrix classes, and C++ does not allow to use operator[] +for matrices since this operator can only take a single argument. +
    +In any case, all deal.II vector classes now support both kinds of +access operators interchangeably. +
    +(Wolfgang Bangerth, 2012/02/12) + +
  24. Fixed: Linking shared libraries on PowerPC systems (e.g. on +BlueGene systems) failed due to a miscommunication between compiler +and linker. This is now worked around. +
    +(Aron Ahmedia, Wolfgang Bangerth, 2012/02/06) + +
  25. New: There is now a distributed deal.II vector class +parallel::distributed::Vector that can be used with MPI. The +vector is based on a contiguous locally owned range and allows easy +access of ghost entries from other processors. The vector interface is +very similar to the non-distributed class Vector. +
    +(Katharina Kormann, Martin Kronbichler, 2012/01/25) + +
  26. Fixed: The common/scripts/make_dependencies program +now behaves like the C++ compiler when +searching include paths for # include "..." directives. +
    +(Timo Heister, 2012/01/10) + +
  27. Fixed: The Intel compiler complains that it can't copy Trilinos vector +reference objects, preventing the compiling of step-32. This is now fixed. +
    +(Wolfgang Bangerth, 2011/11/09) + +
  28. Fixed: Intel ICC 12.1 gets into trouble with BOOST because BOOST +believes that the compiler supports C++0x but one then still has to +specify the corresponding flag on the command line to avoid compiler +errors. This is now fixed. +
    +(Wolfgang Bangerth, 2011/11/06) + +
  29. Fixed: On some systems, mpiCC turns out to alias the +C compiler, not the C++ compiler as expected. Consequently, try to use +mpic++ or mpicxx before mpiCC as +these should really be unambiguous. +
    +(Wolfgang Bangerth, 2011/11/05) + +
  30. Fixed: Intel's ICC compiler identifies itself as icpc version +12.1.0 (gcc version 4.2.1 compatibility) which we mistook as being +GCC version 4.2. The same is true for the Intel C compiler. This is now fixed. +
    +(Wolfgang Bangerth, 2011/11/05) + +
  31. Fixed: deal.II could not be compiled with gcc 4.6.1 when MPI is +enabled due to a missing include file in file +source/base/utilities.cc. This is now fixed. +
    +(Wolfgang Bangerth, 2011/10/25) +
+ + + + + +

Specific improvements

+ +
    +
  1. Changed: To support Trilinos version 10.12.x we need to cache the +result of has_ghost_elements() in parallel vectors at construction time +of the vector. Starting from 10.12 Trilinos will communicate in this +call, which therefore only works if called from all CPUs. +
    +(Timo Heister, 2012/08/22) + +
  2. New: The copy constructor of FullMatrix from IdentityMatrix +used to be explicit, but that didn't appear to be necessary in hindsight. +Consequently, it is now a regular copy constructor. +
    +(Wolfgang Bangerth, 2012/08/14) + +
  3. New: The Patterns::Map pattern allows to describe maps from keys +to values in input files. +
    +(Wolfgang Bangerth, 2012/08/01) + +
  4. Fixed: DoFTools::make_zero_boundary_constraints now also works for parallel distributed triangulations. +
    +(Wolfgang Bangerth, 2012/07/24) + +
  5. Fixed: GridTools::find_active_cell_around_point() works now also if the cell in which the point we look for lies is not adjacent to the closest vertex of p. The tests bits/find_cell_8 and _9 illustrate this. +
    +(Wolfgang Bangerth, Christian Goll 2012/07/20) + +
  6. Fixed: Using the SolutionTransfer class with hp::DoFHandler +and on meshes where some cells are associated with a FE_Nothing element +could result in an error. This is now fixed. +
    +(Wolfgang Bangerth, 2012/06/29) + +
  7. Fixed: The MappingQ1::transform_real_to_unit_cell function as +well as the equivalent ones in derived classes sometimes get into +trouble if they are asked to compute the preimage of this point +in reference cell coordinates. This is because for points outside +the reference cell, the mapping from unit to real cell is not +necessarily invertible, and consequently the Newton iteration to +find the preimage did not always converge, leading to an exception. +While this is not entirely wrong (we could, after all, not compute +the desired quantity), not all callers of this function were prepared +to accept this result -- in particular, the function +CellAccessor<3>::point_inside should have really just returned false +in such cases but instead let the exception so generated propagate +through. This should now be fixed. +
    +(Wolfgang Bangerth, Eric Heien, Sebastian Pauletti, 2012/06/27) + +
  8. Fixed: The function VectorTools::compute_no_normal_flux_constraints had +a bug that led to an exception whenever we were computing constraints for +vector fields located on edges shared between two faces of a 3d cell if those +faces were not parallel to the axes of the coordinate system. This is now fixed. +
    +(Wolfgang Bangerth, Jennifer Worthen, 2012/06/27) + +
  9. +Fixed: Due to an apparent bug in autoconf, it was not possible to +override the F77 environment variable to select anything +else than gfortran. This is now fixed. +
    +(Wolfgang Bangerth, 2012/06/08) + +
  10. Fixed: TrilinosWrappers::VectorBase::swap() is now working as expected. (thanks Uwe Köcher) +
    +(Timo Heister 2012/07/03) + +
  11. Fixed: Some instantiations for +DerivativeApproximation::approximate_derivative_tensor() were missing. +
    +(Timo Heister 2012/06/07) + +
  12. New: The finite element type FE_DGQArbitraryNodes is now +working also in codimension one spaces. +
    +(Luca Heltai, Andrea Mola 2012/06/06) + +
  13. Fixed: Computing the $W^{1,\infty}$ norm and seminorm in +VectorTools::integrate_difference was not implemented. This is now +fixed. +
    +(Wolfgang Bangerth 2012/06/02) + +
  14. Fixed: A problem in MappingQ::transform_real_to_unit_cell +that sometimes led the algorithm in this function to abort. +
    +(Wolfgang Bangerth 2012/05/30) + +
  15. New: The function DataOutInterface::write_pvd_record can be used +to provide Paraview with metadata that describes which time in a +simulation a particular output file corresponds to. +
    +(Marco Engelhard 2012/05/30) + +
  16. Fixed: A bug in 3d with hanging nodes in GridTools::find_cells_adjacent_to_vertex() +that caused find_active_cell_around_point() to fail in those cases. +
    +(Timo Heister, Wolfgang Bangerth 2012/05/30) + +
  17. New: DoFTools::make_periodicity_constraints implemented which +inserts algebraic constraints due to periodic boundary conditions +into a ConstraintMatrix. +
    +(Matthias Maier, 2012/05/22) + +
  18. New: The GridIn::read_unv function can now read meshes generated +by the Salome framework, see http://www.salome-platform.org/ . +
    +(Valentin Zingan, 2012/04/27) + +
  19. New: There is now a second DoFTools::map_dofs_to_support_points +function that also works for parallel::distributed::Triangulation +triangulations. +
    +(Wolfgang Bangerth, 2012/04/26) + +
  20. New: There is now a second DoFTools::extract_boundary_dofs +function that also works for parallel::distributed::Triangulation +triangulations. +
    +(Wolfgang Bangerth, 2012/04/26) + +
  21. New: The FullMatrix::extract_submatrix_from, FullMatrix::scatter_matrix_to, +FullMatrix::set functions are new. +
    +(Andrew McBride, Jean Paul Pelteret, Wolfgang Bangerth, 2012/04/24) + +
  22. Fixed: +The method FEValues::inverse_jacobian() previously returned the transpose of the +inverse Jacobians instead of just the inverse Jacobian as documented. This is now fixed. +
    +(Sebastian Pauletti, Katharina Kormann, Martin Kronbichler, 2012/03/11) + +
  23. Extended: +SolutionTransfer is now also able to transfer solutions between hp::DoFHandler where +the finite element index changes during refinement. +
    +(Katharina Kormann, Martin Kronbichler, 2012/03/10) + +
  24. Changed: +A new method to determine an initial guess for the Newton method was coded +in MappingQ::transform_real_to_unit_cell. +The code in transform_real_to_unit_cell was cleaned a little bit and a new code +for the @<2,3@> case was added. +
    +(Sebastian Pauletti, 2012/03/02) + +
  25. Changed: +In the context of codim@>0, Mapping::transform would require different inputs +depending on the mapping type. +For mapping_covariant, mapping_contravariant the input is DerivativeForm<1, dim, spacedim> +but for mapping_covariant_gradient, mapping_contravariant_gradient the input is Tensor<2,dim>. +
    +(Sebastian Pauletti, 2012/03/02) + +
  26. New: +A new class DerivativeForm was added. +This class is supposed to represent the derivatives of a mapping. +
    +(Sebastian Pauletti, 2012/03/02) + +
  27. Fixed: TrilinosWrappers::Vector::all_zero() in parallel. +
    +(Timo Heister, Jörg Frohne, 2012/03/06) + +
  28. New: GridGenerator::quarter_hyper_shell() in 3d. +
    +(Thomas Geenen, 2012/03/05) + +
  29. New: DataOut::write_vtu_in_parallel(). This routine uses MPI I/O to write +a big vtu file in parallel. +
    +(Timo Heister, 2012/02/29) + +
  30. Fixed: parallel::distributed::Triangulation::clear() forgot +to update the number cache of this class, leading to wrong results +when calling functions like +parallel::distributed::Triangulation::n_global_active_cells(); +
    +(Wolfgang Bangerth, 2012/02/20) + +
  31. Improved: FEFieldFunction allows now for the computation of Laplacians. +
    +(Christian Goll, 2012/02/16) + +
  32. New: The function IndexSet::fill_binary_vector creates a numerical +representation of an IndexSet containing zeros and ones. +
    +(Wolfgang Bangerth, 2012/02/12) + +
  33. New: The function IndexSet::clear resets an index set to be empty. +
    +(Wolfgang Bangerth, 2012/02/12) + +
  34. New: There are now global functions l1_norm() and linfty_norm() that compute +the respective norms of a rank-2 tensor. +
    +(Wolfgang Bangerth, 2012/02/08) + +
  35. New: VectorTools::interpolate_to_different_mesh implemented which interpolates between + DoFHandlers with different triangulations based on a common coarse grid. +
    +(Matthias Maier, 2012/02/08) + +
  36. Improved: DoFTools::map_dofs_to_support_points() now also works within the hp framework. +
    +(Christian Goll, 2012/02/02) + +
  37. Improved: There is now a constructor for FESystem that allows to +create collections of finite elements of arbitrary length. +
    +(Jason Sheldon, 2012/01/27) + +
  38. Improved: VectorTools::point_value() now also works within the hp framework. +
    +(Christian Goll, 2012/01/26) + +
  39. Fixed: GridTools::find_active_cell_around_point() for the hp-case works now also with MappingCollections containing only one mapping, as is the standard case in other functions using hp. +
    +(Christian Goll, 2012/01/26) + +
  40. Fixed: parallel::distributed::refine_and_coarsen_fixed_fraction() +contained a rounding bug that often produced wrong results. +
    +(Timo Heister, 2012/01/24) + +
  41. Improved: Utilities::break_text_into_lines now also splits the string at '\\n'. +
    +(Timo Heister, 2012/01/17) + +
  42. Fixed: When ./configure does not detect the presence +of zlib, writing output in VTU format failed to produce +a valid output file. +
    +(Timo Heister, 2012/01/03) + +
  43. Improved: PETScWrappers::SolverXXX class was +restricted to using default solver options for the KSP only. It is now +possible to override those by using PETSc command-line options +-ksp_*; giving greater flexibility in controlling PETSc +solvers. (See the class's documentation). +
    +(Vijay S. Mahadevan, 2011/12/22) + +
  44. New: The GridIn class now also reads the GMSH format 2.2 as written by +GMSH 2.5. +
    +(Vijay S. Mahadevan, Wolfgang Bangerth, 2011/12/19) + +
  45. Improved: The GridRefinement::refine_and_coarsen_optimize function +assumed that the expected convergence order was 2. It has now gotten an +argument by which the user can prescribe a different value. A bug has also +been fixed in which the function incorrectly assumed in its algorithm that +the mesh was two-dimensional. +
    +(Christian Goll, 2011/12/16) + +
  46. Fixed: Restriction and prolongation didn't work for elements of +kind FE_Nothing. Consequently, many other parts of the library also +didn't work, such as the SolutionTransfer class. This is now fixed. +
    +(Wolfgang Bangerth, 2011/12/15) + +
  47. Fixed: The DerivativeApproximation class now works for distributed computations. +
    +(Timo Heister, 2011/12/15) + +
  48. Changed: The ExcMessage exception class took an argument of +type char* that was displayed when the exception +was raised. However, character pointers are awkward to work with +because (i) they can not easily be composed to contain things like +file names that are only known at run-time, and (ii) the string +pointed to by the pointer had to live longer than the local expression +in which the exception is generated when using the AssertThrow macro +(because, when we create an exception, the exception object is passed +up the call stack until we find a catch-clause; at that time, however, +the scope in which the exception object was created has long been left). +This restriction made it impossible to construct the message using std::string +and then just do something like (std::string("file: ")+filename).c_str(). +
    +To remedy this flaw, the type of the argument to ExcMessage has been +changed to std::string since objects of this type are readily copyable +and therefore live long enough. +
    +(Wolfgang Bangerth, 2011/12/14) + +
  49. New: Setting up a class derived from DataPostprocessor required some +pretty mechanical steps in which one has to overload four member functions. +For common cases where a postprocessor only computes a single scalar or +a single vector, this is tedious and unnecessary. For these cases, the +new classes DataPostprocessorScalar and DataPostprocessorVector provide +short cuts that make life simpler. +
    +(Wolfgang Bangerth, 2011/12/14) + +
  50. Changed: The DataPostprocessor class previously required users of this +class to overload DataPostprocessor::get_names(), +DataPostprocessor::get_data_component_interpretation() +and DataPostprocessor::n_output_variables(). The latter function is redundant +since its output must equal the length of the arrays returned by the +first two of these functions. It has therefore been removed. +
    +(Wolfgang Bangerth, 2011/12/14) + +
  51. Improved: Objects of the type LogStream::Prefix can now be used +as a safe implementation of the push and pop mechanism for log +prefices. +
    +(Guido Kanschat, 2011/12/09) + +
  52. New: IndexSet::add_indices(IndexSet). +
    +(Timo Heister, 2011/12/09) + +
  53. Fixed: Finite element Hessians get computed for codimension one, +at least for FE_Poly derived classes. +
    +(Guido Kanschat, 2011/12/07) + +
  54. Changed: Output of ParameterHandler::print_parameters with argument +ParameterHandler::LaTeX was not particularly readable. The output has +therefore been rewritten to be more structured and readable. +
    +(Wolfgang Bangerth, 2011/11/28) + +
  55. Fixed: The TimerOutput class set the alignment of output to right-aligned +under some circumstances, but didn't reset this to the previous value at the +end of output. This is now fixed. +
    +(Wolfgang Bangerth, 2011/11/28) + +
  56. New: The copy constructor of the SparseMatrixEZ function now works +(rather than throwing an exception) if the copied matrix has size zero. +This is in accordance to the other matrix classes. +
    +(Wolfgang Bangerth, 2011/11/15) + +
  57. New: The class ScalarFunctionFromFunctionObject provides a quick way to +convert an arbitrary function into a function object that can be passed +to part of the library that require the Function@ interface. +The VectorFunctionFromScalarFunctionObject class does a similar thing. +
    +(Wolfgang Bangerth, 2011/11/15) + +

  59. New: FETools::get_fe_from_name() can now return objects of type FE_Nothing. +
    +(Scott Miller, Jonathan Pitt, 2011/11/10) + +
  60. New: Implementation of an alternative handling of +inhomogeneous constraints in ConstraintMatrix. This is controlled with +a new parameter use_inhomogeneities_for_rhs in +distribute_local_to_global() and determines whether the correct or +zero values (this was the case before and still is the default) are +kept in the linear system during the solution process. +
    +(Jörg Frohne, 2011/11/01) + +
  61. Fixed: SparseMatrix::mmult and SpareMatrix::Tmmult had a number of +issues that are now fixed: (i) rebuilding the sparsity pattern was allowed +even if several of the matrices involved in these operations shared a +sparsity pattern; (ii) the functions had a vector argument that had a default +value but the default value could not be used because it wasn't used in a +template context deducible by the compiler. +
    +(Wolfgang Bangerth, 2011/10/30) + +
  62. New: +parallel::distributed::Triangulation::mesh_reconstruction_after_repartitioning +setting which is necessary for save()/load() to be deterministic. Otherwise +the matrix assembly is done in a different order depending on the order of old +refinements. +
    +(Timo Heister, 2011/10/26) + +
  63. New: TriaAccessor<>::minimum_vertex_distance(). +
    +(Timo Heister, 2011/10/25) + +
  64. New: TableHandler::print_text now supports not only printing column +keys above their own column, but also in a separate header, to make it simpler +for external plotting programs to skip this line. +
    +(Wolfgang Bangerth, 2011/10/22) + +
  65. Fixed: Trying to write a TableHandler object that is empty resulted +in a segmentation fault. This is now fixed. +
    +(Wolfgang Bangerth, 2011/10/21) + +
  66. New: The TableHandler class can now pad columns that have only been +partially filled. See the documentation of the class for a description. +
    +(Wolfgang Bangerth, 2011/10/18) + +
  67. Fixed: In TableHandler::print_text, it can happen that the function +wants to print an empty string as the element of the table to be printed. +This can confuse machine readers of this table, for example for visualization, +since they then do not see this column in that row. To prevent this, we now +print "" in such places. +
    +(Wolfgang Bangerth, 2011/10/18) + +
  68. Fixed: Using Trilinos versions 10.4 and later on Debian failed to +configure due to a different naming scheme of Trilinos libraries on +Debian. This is now fixed. +
    +(Wolfgang Bangerth, 2011/10/17) + +
  69. Changed: The TableHandler class has been changed significantly +internally. It could previously store arbitrary values (though in practice, +only int, unsigned int, double and std::string were implemented). The class is +now restricted to this particular set of types. On the other hand, the +TableHandler class can now be serialized. +
    +(Wolfgang Bangerth, 2011/10/17) + +
  70. Fixed: searching in the doxygen documentation. +
    +(Timo Heister, 2011/10/13) + +
  71. New: parallel::distributed::Triangulation::save()/load() to store +the refinement information to disk. Also supports saving solution vectors +using the SolutionTransfer class. +

  1. Changed/fixed: Several operations on Trilinos vectors that change the -elements of these vectors were allowed accidentally for vectors that have -ghost elements. This is a source of errors because a change on one -MPI process will not show up on a different processor. Consequently, we -intended to disallow all functions that modify vectors with ghost elements -but this was not enforced for all of these functions. This is now fixed -but it may lead to errors if your code relied on the existing behavior. The -way to work around this is to only ever modify fully distributed vectors, -and then copy it into a vector with ghost elements. -

  21. Changed: Material and Boundary indicators have been both of the -type unsigned char. Throughout the library, we changed their datatype -to types::material_id -resp. types::boundary_id, both typedefs of unsigned -char. Internal faces are now characterized by -numbers::internal_face_boundary_id(=static_cast@(-1)) -instead of 255, so we get rid of that mysterious number in the source -code. Material_ids are also assumed to lie in the range from 0 to -numbers::invalid_material_id-1 (where numbers::invalid_material_id = -static_cast(-1)). With this change, it is now -much easier to extend the range of boundary or material ids, if -needed. -
    -(Christian Goll 2012/02/27) - -
  22. New: Functions like FEValues::get_function_values have long been -able to extract values from pretty much any vector kind given to it (e.g. -of kind Vector, BlockVector, PETScWrappers::Vector, etc). The list of -allowed "vector" types now also includes IndexSet, which is interpreted -as a vector of elements that are either zero or one, depending on whether -an index is in the IndexSet or not. -
    -As a consequence of this, the DataOut::add_data_vector functions now also -work for such types of vectors, a use demonstrated in step-41. -
    -(Wolfgang Bangerth, 2012/02/14) - -
  23. New: It has long been a nuisance that the deal.II vector classes -could only be accessed using operator() whereas the C++ -std::vector class required operator[]. This -diminished the usefulness of template code. Historically, the reason -was that the deal.II vector classes should use the same operator as -the matrix classes, and C++ does not allow to use operator[] -for matrices since this operator can only take a single argument. -
    -In any case, all deal.II vector classes now support both kinds of -access operators interchangeably. -

  25. New: There is now a distributed deal.II vector class -parallel::distributed::Vector that can be used with MPI. The -vector is based on a contiguous locally owned range and allows easy -access of ghost entries from other processors. The vector interface is -very similar to the non-distributed class Vector. -

    -(Wolfgang Bangerth, 2011/11/09) - -
  28. Fixed: Intel ICC 12.1 gets into trouble with BOOST because BOOST -believes that the compiler supports C++0x but one then still has to -specify the corresponding flag on the command line to avoid compiler -errors. This is now fixed. -
    -(Wolfgang Bangerth, 2011/11/06) - -
  29. Fixed: On some systems, mpiCC turns out to alias the -C compiler, not the C++ compiler as expected. Consequently, try to use -mpic++ or mpicxx before mpiCC as -these should really be unambiguous. -
    -(Wolfgang Bangerth, 2011/11/05) - -
  30. Fixed: Intel's ICC compiler identifies itself as icpc version -12.1.0 (gcc version 4.2.1 compatibility) which we mistook as being -GCC version 4.2. The same is true for the Intel C compiler. This is now fixed. -
    -(Wolfgang Bangerth, 2011/11/05) - -
  31. Fixed: deal.II could not be compiled with gcc 4.6.1 when MPI is -enabled due to a missing include file in file -source/base/utilities.cc. This is now fixed. -

  5. Fixed: GridTools::find_active_cell_around_point() works now also if the cell in which the point we look for lies is not adjacent to the closest vertex of p. The tests bits/find_cell_8 and _9 illustrate this. -

  7. Fixed: The MappingQ1::transform_real_to_unit_cell function as -well as the equivalent ones in derived classes sometimes get into -trouble if they are asked to compute the preimage of this point -in reference cell coordinates. This is because for points outside -the reference cell, the mapping from unit to real cell is not -necessarily invertible, and consequently the Newton iteration to -find the preimage did not always converge, leading to an exception. -While this is not entirely wrong (we could, after all, not compute -the desired quantity), not all callers of this function were prepared -to accept this result -- in particular, the function -CellAccessor<3>::point_inside should have really just returned false -in such cases but instead let the exception so generated propagate -through. This should now be fixed. -

  8. Fixed: The function VectorTools::compute_no_normal_flux_constraints had -a bug that led to an exception whenever we were computing constraints for -vector fields located on edges shared between two faces of a 3d cell if those -faces were not parallel to the axes of the coordinate system.

    -(Vijay S. Mahadevan, Wolfgang Bangerth, 2011/12/19) - -
  45. Improved: The GridRefinement::refine_and_coarsen_optimize function -assumed that the expected convergence order was 2. It has now gotten an -argument by which the user can prescribe a different value. A bug has also -been fixed in which the function incorrectly assumed in its algorithm that -the mesh was two-dimensional. -
    -(Christian Goll, 2011/12/16) - -
  46. Fixed: Restriction and prolongation didn't work for elements of -kind FE_Nothing. Consequently, many other parts of the library also -didn't work, such as the SolutionTransfer class. This is now fixed. -

  47. Fixed: The DerivativeApproximation class now works for distributed computations. -
    -(Timo Heister, 2011/12/15) - -
  48. Changed: The ExcMessage exception class took an argument of -type char* that was displayed when the exception -was raised. However, character pointers are awkward to work with -because (i) they can not easily be composed to contain things like -file names that are only known at run-time, and (ii) the string -pointed to by the pointer had to live longer than the local expression -in which the exception is generated when using the AssertThrow macro -(because, when we create an exception, the exception object is passed -up the call stack until we find a catch-clause; at that time, however, -the scope in which the exception object was created has long been left). -This restriction made it impossible to construct the message using std::string -and then just do something like (std::string("file: ")+filename).c_str(). -
    -To remedy this flaw, the type of the argument to ExcMessage has been -changed to std::string since objects of this type are readily copyable -and therefore live long enough. -
    -(Wolfgang Bangerth, 2011/12/14) - -
  49. New: Setting up a class derived from DataPostprocessor required some -pretty mechanical steps in which one has to overload four member functions. -For common cases where a postprocessor only computes a single scalar or -a single vector, this is tedious and unnecessary. For these cases, the -new classes DataPostprocessorScalar and DataPostprocessorVector provide -short cuts that make life simpler. -
    -(Wolfgang Bangerth, 2011/12/14) - -
  50. Changed: The DataPostprocessor class previously required users of this -class to overload DataPostprocessor::get_names(), -DataPostprocessor::get_data_component_interpretation() -and DataPostprocessor::n_output_variables(). The latter function is redundant -since its output must equal the length of the arrays returned by the -first two of these functions. It has therefore been removed. -
    -(Wolfgang Bangerth, 2011/12/14) - -
  51. Improved: Objects of the type LogStream::Prefix can now be used -as a safe implementation of the push and pop mechanism for log -prefices. -
    -(Guido Kanschat, 2011/12/09) - -
  52. New: IndexSet::add_indices(IndexSet). -
    -(Timo Heister, 2011/12/09) - -
  53. Fixed: Finite element Hessians get computed for codimension one, -at least for FE_Poly derived classes. -
    -(Guido Kanschat, 2011/12/07) - -
  54. Changed: Output of ParameterHandler::print_parameters with argument -ParameterHandler::LaTeX was not particularly readable. The output has -therefore been rewritten to be more structured and readable. -
    -(Wolfgang Bangerth, 2011/11/28) - -
  55. Fixed: The TimerOutput class set the alignment of output to right-aligned -under some circumstances, but didn't reset this to the previous value at the -end of output. This is now fixed. -
    -(Wolfgang Bangerth, 2011/11/28) - -
  56. New: The copy constructor of the SparseMatrixEZ function now works -(rather than throwing an exception) if the copied matrix has size zero. -This is in accordance to the other matrix classes. -
    -(Wolfgang Bangerth, 2011/11/15) - -
  57. New: The class ScalarFunctionFromFunctionObject provides a quick way to -convert an arbitrary function into a function object that can be passed -to part of the library that require the Function@ interface. -The VectorFunctionFromScalarFunctionObject class does a similar thing. -
    -(Wolfgang Bangerth, 2011/11/15) - -
  58. New: The DoFTools::count_dofs_per_block function now also works -for objects of type hp::DoFHandler. -
    -(Jason Sheldon, 2011/11/13) - -
  59. New: FETools::get_fe_from_name() can now return objects of type FE_Nothing. -
    -(Scott Miller, Jonathan Pitt, 2011/11/10) - -
  60. New: Implementation of an alternative handling of -inhomogeneous constraints in ConstraintMatrix. This is controlled with -a new parameter use_inhomogeneities_for_rhs in -distribute_local_to_global() and determines whether the correct or -zero values (this was the case before and still is the default) are -kept in the linear system during the solution process. -
    -(Jörg Frohne, 2011/11/01) - -
  61. Fixed: SparseMatrix::mmult and SpareMatrix::Tmmult had a number of -issues that are now fixed: (i) rebuilding the sparsity pattern was allowed -even if several of the matrices involved in these operations shared a -sparsity pattern; (ii) the functions had a vector argument that had a default -value but the default value could not be used because it wasn't used in a -template context deducible by the compiler. -
    -(Wolfgang Bangerth, 2011/10/30) - -
  62. New: -parallel::distributed::Triangulation::mesh_reconstruction_after_repartitioning -setting which is necessary for save()/load() to be deterministic. Otherwise -the matrix assembly is done in a different order depending on the order of old -refinements. -
    -(Timo Heister, 2011/10/26) - -
  63. New: TriaAccessor<>::minimum_vertex_distance(). -
    -(Timo Heister, 2011/10/25) - -
  64. New: TableHandler::print_text now supports not only printing column -keys above their own column, but also in a separate header, to make it simpler -for external plotting programs to skip this line. -
    -(Wolfgang Bangerth, 2011/10/22) - -
  65. Fixed: Trying to write a TableHandler object that is empty resulted -in a segmentation fault. This is now fixed. -
    -(Wolfgang Bangerth, 2011/10/21) - -
  66. New: The TableHandler class can now pad columns that have only been -partially filled. See the documentation of the class for a description. -
    -(Wolfgang Bangerth, 2011/10/18) - -
  67. Fixed: In TableHandler::print_text, it can happen that the function -wants to print an empty string as the element of the table to be printed. -This can confuse machine readers of this table, for example for visualization, -since they then do not see this column in that row. To prevent this, we now -print "" in such places. -
    -(Wolfgang Bangerth, 2011/10/18) - -
  68. Fixed: Using Trilinos versions 10.4 and later on Debian failed to -configure due to a different naming scheme of Trilinos libraries on -Debian. This is now fixed. -
    -(Wolfgang Bangerth, 2011/10/17) - -
  69. Changed: The TableHandler class has been changed significantly -internally. It could previously store arbitrary values (though in practice, -only int, unsigned int, double and std::string were implemented). The class is -now restricted to this particular set of types. On the other hand, the -TableHandler class can now be serialized. -
    -(Wolfgang Bangerth, 2011/10/17) - -
  70. Fixed: searching in the doxygen documentation. -
    -(Timo Heister, 2011/10/13) - -
  71. New: parallel::distributed::Triangulation::save()/load() to store -the refinement information to disk. Also supports saving solution vectors -using the SolutionTransfer class. -
    -(Timo Heister, 2011/10/12) - -
  72. Fixed: The DataOut_DoFData::merge_patches did not compile with newer compilers. -This is now fixed. -
    -(Wolfgang Bangerth, 2011/10/11) +
  73. Nothing so far.
