Changes between versions 3.2.0 and 3.3.0

+ +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

+ +

+ New: Output for + Tecplot has + been added. It can be used by choosing output format «tecplot». +
+ (Benjamin Shelton Kirk 2002/01/29) +
+ +
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) +
+ +
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) +
+ +
+ 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) +
+ +
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) +
+ +
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) +
+ +
New: example program step-12. Discontinuous Galerkin + discretization. +
+ (RH 2001/11/21) +
+ +
+ 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) +
+ +
+ 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) +
+ +
+ New: the ./configure script now recognizes gcc3.1 + (i.e. presently prereleases of it) and sets compilation flags + accordingly. +
+ (WB 2001/10/25) +
+

+ + + + +

base

+ +

+ 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) +
+ +
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) +
+ +
+ 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) +
+ +
+ 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) +
+ +
+ 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) +
+ +
+ New: ExcFileNotOpen can be used + after initializing an fstream + object. This allows to avoid some cryptic ExcIOs. +
+ (GK 2001/12/18) +
+ +
+ Changed: The OutputStyle enum used + to indicate the output format has been moved into the + ParameterHandler class. +
+ (WB 2001/11/30) +
+ +
+ Fixed: In the ParameterHandler + class, we leaked 8 or 12 bytes of memory per declared + parameter. This is now fixed. +
+ (WB 2001/11/28) +
+ +
+ 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) +
+ +
+ 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

+ +

+ 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) +
+ +
+ Fixed: The FilteredMatrix::allocate_tmp_vector + function had a bug with block vectors. +
+ (WB 2001/11/22) +
+ +
+ Improved: reinit function of Vector + and BlockVector allows use of a + vector with different number type. +
+ (GK 2001/11/21) +
+ +
+ 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) +
+ +
+ New: the SparseDirectMA27/47 classes + now provide access to Mutex locks for external + synchronisation. +
+ (WB 2001/11/14) +
+ +
+ Fixed: an error in the definition of the SolverMinRes::solve function prevented + its compilation under some circumstances. +
+ (WB 2001/11/14) +
+ +
+ Fixed: upon breakdown, the SolverBicgstab forgot to increment the + iteration counter for the breakdown cycle. This is now fixed. +
+ (WB 2001/11/14) +
+ +
+ Improved: class SolverGMRES accepts + a parameter in AdditionalData, + allowing for right preconditioning. +
+ (GK 2001/11/09) +
+ +
+ 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) +
+ +
+ 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) +
+ +
New: Vector::operator * is now templatized, allowing + for scalar products of vectors with different underlying types. +
+ (WB 2001/09/27) +
+

+ + + + +

deal.II

+ +

+ New: The FilteredIterator class + provides a view on ranges of iterators by iterating over only + those objects that satisfy a certain predicate. +
+ (GK 2002/01/07) +
+ +
+ 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) +
+ +
+ 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) +
+ +
+ New: GridGenerator has a function + cylinder for cylinders in three + space dimensions. Accoridngly, a class CylinderBoundary has been created. +
+ (GK 2001/12/07) +
+ +
+ 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) +
+ +
+ 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) +
+ +
+ 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) +
+ +
+ Fixed: The functions Mapping::transform_unit_to_real_cell + leaked some memory. This is now fixed. +
+ (RH, WB 2001/11/28) +
+ +
+ Fixed: The DoFHandler class had a + memory leak. This is now fixed. Likewise for the MGDoFHandler class. +
+ (WB 2001/11/28) +
+ +
+ Fixed: The GridRefinement::refine + function failed when the threshold was zero. This is now fixed. +
+ (RH 2001/11/26) +
+ +
+ Fixed: The MappingQ::transform_real_to_unit_cell + function failed on a very unusual cell. This is now fixed. +
+ (RH 2001/11/26) +
+ +
+ New: The new CellAccessor::neighbor_of_coarser_neighbor + function returns where to find the present cell from a coarser + neighbor. +
+ (RH 2001/11/21) +
+ +
+ 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) +
+ +
+ New: DoFTools::extract_subdomain_dofs selects + those degrees of freedom which are located on cells with a + specified subdomain id. +
+ (WB 2001/10/27) +
+ +
+ 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) +
+ +
+ Fixed: the GridGenerator::hyper_rectangle function + was broken in 3d. +
+ (WB 2001/10/26) +
+ +
+ Improved: Both functions DataOut_DoFData::add_data_vector accepts BlockVector as argument. +
+ (GK 2001/10/12) +
+ +
+ 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) +
+ +
+ Fixed: Functions creating sparsity patterns for DG elements in + DoFTools get the pattern type as + template argument, too.. +
+ (GK 2001/10/01) +
+ +
+ Fixed: the iterator category template base class of grid + iterators was incorrectly set. +
+ (WB 2001/09/28) +
