Changes after Version 3.2

- -This is the list of changes made after the release of -deal.II version 3.2. It is subdivided into changes -made to the three sub-libraries base, -lac, and deal.II, as well as -changes to the general infrastructure, -documentation, etc. - - - - -

General

- -
    -

  1. - New: Output for - Tecplot has - been added. It can be used by choosing output format «tecplot». -
    - (Benjamin Shelton Kirk 2002/01/29) -

    - -

  2. New: configuration detects whether the compiler has the - include file <ostream>. Most files in the - library then include this file over - <iostream> to save compile time. -
    - (WB 2002/01/25) -

    - -

  3. Fixed: All example and test programs as well as a number of - large applications have been checked against the memory checker - "purify". Only three memory leaks were found and fixed. We - believe that no major leaks exist in the library any more. -
    - (WB 2001/12/07) -

    - -

  4. - New: Output for - OpenDX has - been added. It can be used by choosing output format «dx» (not - yet for grid output). The data format is very basic now, but it - is planned to improve this to make use of the excellent - capabilites of OpenDX. -

    -

    - Additionally, a directory contrib/dx has been added, - containing visual programs for OpenDX. Programs for the - existing output of data as a single vector are found in the - subdirectory single. -
    - (GK 2001/12/07) -

    - -

  5. Fixed: Previously, the $(INCLUDE) variable in Makefiles - included the values of the $INCLUDE environment variable. This - is not desirable, since the compiler evaluates that variable - anyway and the Makefile variable has -I prefixed - to all paths while the environment variable has not. -
    - (WB 2001/11/29) -

    - -

  6. Removed: the option to generate printable documentation was - removed. Since this comprised approximately 2000 pages and - since we believe that the online documentation is rather good, - this is probably no big loss. -
    - (WB 2001/11/29) -

    - -

  7. New: example program step-12. Discontinuous Galerkin - discretization. -
    - (RH 2001/11/21) -

    - -

  8. - New: deal.II now uses a file - config.h for most global preprocessor defines, - instead of an overly long list of compiler flags given on the - command line. -
    - (WB 2001/10/27) -

    - -

  9. - Changed: If available, the library now uses the C++ standard - classes istringstream and ostringstream over the old classes - i/ostrstream. The ./configure script - finds out whether the new classes exist, or whether the - backward compatibility classes are to be used. -
    - (WB 2001/10/25) -

    - -

  10. - New: the ./configure script now recognizes gcc3.1 - (i.e. presently prereleases of it) and sets compilation flags - accordingly. -
    - (WB 2001/10/25) -

    -
- - - - -

base

- -
    -

  1. - Fixed: For Mac OS X, the file base/source/log.cc - needed to include sys/time.h in addition to - sys/resource.h. -
    - (Alexis Herault, WB 2002/01/28) -

    - -

  2. Fixed: Private definitions of the copy constructor and - assignment operator of the ParameterHandler class are now included in - order to inhibit the (unintentional) use of default copy - constructors. -
    - (RH 2002/01/22) -

    - -

  3. - Improved: The cut-off functions Functios::CutOffFunctionLinfty, Functios::CutOffFunctionW1, and Functios::CutOffFunctionCinfty can be - vector-valued now and optionally only a single componente can - be selected. -
    - (GK 2002/01/10) -

    - -

  4. - New: the deal_II_exceptions::set_additional_assert_output - function allows to set additional output to be printed upon - triggering an Assert() call. This - is helpful for parallel applications where you only see the - text of the message but do not know from which cluster node it - stems. -
    - (WB 2002/01/10) -

    - -

  5. - Changed: when an assertion fails in the Assert() function, the program is usually - aborted. Don't abort it any more if there is an active C++ - exception somewhere since we would lose its message if we - aborted the program. In that case only report the error and - write out an indication why we do not abort the program any - more. On the other hand, also suppress output of further failed - Assert() calls, since they often - are follow-ups of the first one. -
    - (WB 2002/01/09) -

    - -

  6. - New: ExcFileNotOpen can be used - after initializing an fstream - object. This allows to avoid some cryptic ExcIOs. -
    - (GK 2001/12/18) -

    - -

  7. - Changed: The OutputStyle enum used - to indicate the output format has been moved into the - ParameterHandler class. -
    - (WB 2001/11/30) -

    - -

  8. - Fixed: In the ParameterHandler - class, we leaked 8 or 12 bytes of memory per declared - parameter. This is now fixed. -
    - (WB 2001/11/28) -

    - -

  9. - New: Functions::CutOffFunctionCinfty, - Functions::CutOffFunctionW1, and - Functions::CutOffFunctionLinfty - implement functions with support in an arbitrary ball and - differentiability as indicated by their name -
    - (GK 2001/10/24) -

    - -

  10. - Fixed: The DataOutBase::EpsFlags - class forgot to declare the reverse grey scale function as one - possible input for the color function for the - ParameterHandler class. This is now - possible. -
    - (WB 2001/10/10) -

    -
- - - - -

lac

- -
    -

  1. - - Improved: all sparsity pattern classes have a function exists, allowing you to check whether a - certain index pair has been allocated in the pattern. -
    - (GK 2002/02/01) -

    - -

  2. - Fixed: Allocation of temporary vectors in FilteredMatrix::allocate_tmp_vector - is now faster since it does no more copy the value of the - template vector. -
    - (WB 2001/11/22) -

    - -

  3. - Fixed: The FilteredMatrix::allocate_tmp_vector - function had a bug with block vectors. -
    - (WB 2001/11/22) -

    - -

  4. - Improved: reinit function of Vector - and BlockVector allows use of a - vector with different number type. -
    - (GK 2001/11/21) -

    - -

  5. - Fixed: when checking for convergence in linear solvers in - SolverControl::check, we first - checked whether the maximal iteration count was reached, and - only then whether the target residual was achieved. In cases, - where the target residual was only reached in the very last - allowed iteration, this led to a failure notice of the linear - solver, rather than to a success message. This is now fixed. -
    - (WB 2001/11/19) -

    - -

  6. - New: the SparseDirectMA27/47 classes - now provide access to Mutex locks for external - synchronisation. -
    - (WB 2001/11/14) -

    - -

  7. - Fixed: an error in the definition of the SolverMinRes::solve function prevented - its compilation under some circumstances. -
    - (WB 2001/11/14) -

    - -

  8. - Fixed: upon breakdown, the SolverBicgstab forgot to increment the - iteration counter for the breakdown cycle. This is now fixed. -
    - (WB 2001/11/14) -

    - -

  9. - Improved: class SolverGMRES accepts - a parameter in AdditionalData, - allowing for right preconditioning. -
    - (GK 2001/11/09) -

    - -

  10. - Fixed: class SparsityPattern can - handle rows of length zero now. For quadratic matrices, these - rows are changed to length one, since a diagonal element must - be stored. -
    - (GK 2001/10/11) -

    - -

  11. - New: The BlockVector now has a - full-fledged random access iterator type, working in exactly - the same way as the iterators of the C++ standard containers. -
    - (WB 2001/09/28) -

    - -

  12. New: Vector::operator * is now templatized, allowing - for scalar products of vectors with different underlying types. -
    - (WB 2001/09/27) -

    -
- - - - -

deal.II

- -
    -

  1. - Changed: The classes FEQ1-FEQ4, FEDG_Q1FEDG_Q4 - as well as the files with their definitions, - fe/fe_lib.lagrange.h and fe/fe_lib.dg.h - ceased to exist. They had been left in for backward - compatibility in an earlier version, but their existence is - more confusing than helpful. Please change your code to use the - classes FE_Q and FE_DGQ, respectively. -
    - (GK 2002/02/01) -

    - -

  2. - New: The FilteredIterator class - provides a view on ranges of iterators by iterating over only - those objects that satisfy a certain predicate. -
    - (WB 2002/01/07) -

    - -

  3. - Improved: It is now possible to read in unconnected domains - through the GridIn class, since - renumbering the cells now also works for these domains. -
    - (Michael Stadler 2001/12/14) -

    - -

  4. - Improved: Both functions VectorTools::compute_mean_value take ingoing and - outgoing vector types as template arguments. This allows - applying them to BlockVector. -
    - (GK 2001/12/07) -

    - -

  5. - New: GridGenerator has a function - cylinder for cylinders in three - space dimensions. Accoridngly, a class CylinderBoundary has been created. -
    - (GK 2001/12/07) -

    - -

  6. - New: FiniteElement::has_support_on_face allows to check - whether a shape function has non-zero values on a certain face - of a cell. -
    - (GK 2001/12/04) -

    - -

  7. - Changed: The IteratorState enum used - to indicate the state in which an iterator can be is now - enclosed in a namespace of the same name, to take its members - out of the global namespace. When using one of these members, - you now have to prefix it by IteratorState::. -
    - (WB 2001/11/30) -

    - -

  8. - Changed: The NormType enum used to - indicate the norm the VectorTools::integrate_difference - function shall integrate is moved from the global namespace - into the VectorTools class. You - therefore have to prefix the members of this enum by the - respective class name. -
    - (WB 2001/11/29) -

    - -

  9. - Fixed: The functions Mapping::transform_unit_to_real_cell - leaked some memory. This is now fixed. -
    - (RH, WB 2001/11/28) -

    - -

  10. - Fixed: The DoFHandler class had a - memory leak. This is now fixed. Likewise for the MGDoFHandler class. -
    - (WB 2001/11/28) -

    - -

  11. - Fixed: The GridRefinement::refine - function failed when the threshold was zero. This is now fixed. -
    - (RH 2001/11/26) -

    - -

  12. - Fixed: The MappingQ::transform_real_to_unit_cell - function failed on a very unusual cell. This is now fixed. -
    - (RH 2001/11/26) -

    - -

  13. - New: The new CellAccessor::neighbor_of_coarser_neighbor - function returns where to find the present cell from a coarser - neighbor. -
    - (RH 2001/11/21) -

    - -

  14. - Fixed: The GridRefinement::refine_fixed_fraction - function sometimes had problems when indicators vary over - several orders of magnitude, due to roundoff. This is now - fixed. -
    - (WB 2001/11/05) -

    - -

  15. - New: DoFTools::extract_subdomain_dofs selects - those degrees of freedom which are located on cells with a - specified subdomain id. -
    - (WB 2001/10/27) -

    - -

  16. - New: Cells now have an additional property - subdomain_id which can be used in parallel - computations to identify which cells are handled on which - processor. These flags are read and set using the functions - cell->subdomain_id() and cell->set_subdomain_id(new_id). The - subdomain ids are unsigned integers, so should be sufficiently - large also for larger numbers of subdomains. -
    - (WB 2001/10/27) -

    - -

  17. - Fixed: the GridGenerator::hyper_rectangle function - was broken in 3d. -
    - (WB 2001/10/26) -

    - -

  18. - Improved: Both functions DataOut_DoFData::add_data_vector accepts BlockVector as argument. -
    - (GK 2001/10/12) -

    - -

  19. - Improved: Both functions VectorTools::integrate_difference take ingoing and - outgoing vector types as template arguments. This allows - applying them to BlockVector and of - outputting a vector of doubles suitable for DataOut. -
    - (GK 2001/10/12) -

    - -

  20. - Fixed: Functions creating sparsity patterns for DG elements in - DoFTools get the pattern type as - template argument, too.. -
    - (GK 2001/10/01) -

    - -

  21. - Fixed: the iterator category template base class of grid - iterators was incorrectly set. -
    - (WB 2001/09/28) -
