Changes between versions 3.3.0 and 3.4.0

+ +

+This is a quite extensive list of changes made between versions 3.2.0 +and 3.3.0 of deal.II. 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

+ +

+ + Deprecated: The functions FEValuesBase::get_shape_values, FEValuesBase::get_shape_grads, and FEValuesBase::get_shape_2nd_derivatives are + now deprecated as they expose too much of the internal data + structure of their class, and interfere with plans for the + extension of this and related classes. The functions still + exist in this release of the library, but will be removed in + the next version. Use the FEValuesBase::shape_value and alike + functions as a replacement. +
+ For more information, read + this mail. + +
+ (WB 2002/06/03) +
+ +
+ Added: The configure script now recognizes Intel's ECC + compiler when run on Itanium systems with this compiler present. + The ECC compiler is similar to the ICC compiler but it acccepts some + different options. +
+ (BK 2002/05/22) +
+ +
+ New: The step-14 example program demonstrates duality based + error estimators and some more software design concepts. +
+ (WB 2002/05/05) +
+ +
+ New: In all previous versions, deal.II used + the ACE (Adaptive Communications Environment) + library to support cross-platform threading + facilities. While this is still supported, the default way + is now to use the POSIX threading functions that are + available on many systems. The relieves you from the need of + installing a huge library of which the most part is not used + anyway. However, if you use ACE for other reasons, then it is + still supported. For installation instructions, see the + ReadMe file. +
+ (WB 2002/04/30) +
+ +
+ Changed: The Makefiles for the library are now truly + parallel. To this end, the automatic generation of the files + forward_declarations.h in the various directories had + to be changed. They will now be generated automatically at the + end of the targets all, debug and + optimized. They will not be generated while building a + single library. In this case, make forward can be used + to build them manually. +
+ I introduced separate targets for the generation of the + optimized versions only. +
+ (GK 2002/04/17) +
+ +
+ New: The step-13 example program tells you something about + software design things for finite element programs. +
+ (WB 2002/04/16) +
+ +
+ Changed: Due to problems with undeclared functions and general + compatibility concerns, -ansi is now no more part + of the compile flags for gcc. +
+ (WB 2002/04/16) +
+ +
+ Fixed: Explicit specializations of member templates are now + conforming to the C++ standard. While most compilers accepted + the previous form, Sun's Forte compiler wants a strictly + conforming one. +
+ (WB 2002/03/25) +
+ +
+ Fixed: For gcc versions that used ostrstream instead of ostringstream, it was necessary to append + a final std::ends when piping text + into the string stream. This was not previously + conditionalized, but done for old and new classes. +
+ (WB 2002/03/13) +
+ +
+ Changed: The configure machinery has been revamped + significantly. +
+ (WB 2002/03/08) +
+ +
+ Added: The top-level Makefile now supports "optimized" as a + target that builds only optimized versions of the base, + lac, 1d, 2d, and 3d + libraries. +
+ (BK 2002/02/19) +
+ +
+ Changed: The build system was entirely revised. Object + files in debug mode now have the suffix .g.o + instead of .go. All object files from the + subdirectories are now placed into the /lib + top-level directory, rather than in library directories in the + individual subdirs. +
+ (WB 2002/02/11) +
+

+ + + + +

base

+ +

+ New: The vector2d row accessor + classes now have member functions begin and end + which allow iterating over the elements of a row of such an + object. +
+ (WB 2002/05/30) +
+ +
+ New: The Legendre and + LagrangeEquidistant classes now have + static member functions generate_complete_basis which returns an + array of polynomial objects spanning the complete space up to a + specified order in 1d. This may be used to generate the + respective polynomial spaces in higher space dimensions. +
+ (WB 2002/05/27) +
+ +
+ Changed: The Polynomial and + LagrangeEquidistant classes have lost + their default constructor, as that did not make much sense + anyway. +
+ (WB 2002/05/27) +
+ +
+ Fixed: When forward declaring the Tensor class, we now also forward declare + its partial specialization for a rank one tensor. Not doing so + confused Sun's Forte compiler. +
+ (WB 2002/03/22) +
+ +
+ Fixed: The class TensorFunction + now uses local types value_type and + gradient_type as return values of + its member functions. This works around a bug in Sun's Forte + C++ compilers. +
+ (WB 2002/03/20) +
+ +
+ Improved: The AssertThrow macro now + uses __builtin_expect if the + compiler supports this. This indicates to the compiler that we + expect the condition to be true and that throwing an exception + is a rare case. By this information, the compiler can help the + branch prediction unit of modern processors to better predict + which direction a branch will take. +
+ (WB 2002/03/13) +
+ +
+ New: The vector2d class now not only + allows access to elements through the operator()(unsingned int,unsigned int) + (i.e. matrix or Fortran style access), but also through nested + brackets via an operator[] + (i.e. like to a two-dimensional C-style array). +
+ (WB 2002/03/08) +
+ +
+ Changed: The function MultithreadInfo:: + get_n_cpus now reports the proper number + of CPUs when running on Silicon Graphics. +
+ (BK 2002/02/19) +
+ +
+ Changed: The quite logorrhoeic function name TensorProductPolynomials::n_tensor_product_polynomials was changed to + n to be compliant wth the new class PolynomialSpace. +
+ (GK 2002/02/11) +
+ +
+ New: The class PolynomialSpace + implements the space of polynomials at most a certain degree in + arbitrary space dimensions. +
+ (GK 2002/02/11) +
+ +
+ New: The function DataOutBase:: + write_tecplot_binary has been + added. This function will write Tecplot binary files if the + Tecplot API is detected by ./configure. To use this feature be + sure that the environment variable TECHOME points to a valid + Tecplot installation and that the files + $TECHOME/include/TECIO.h and $TECHOME/lib/tecio.a exist. The + name of the file to be written is specified through the DataOutBase ::TecplotFlags. tecplot_binary_file_name variable. If the + API is not available this code simply calls the existing ASCII + output function. +
+ (BK 2002/02/11) +
+

+ + + + +

lac

+ +

Improved: SolverGMRES allocates + basis vectors only, when they are needed. Therefore, it is safe + now to ask for a basis larger than the expected number of + iteration steps. On the other hand, memory allocation failures + may occur during the iteration now. +
+ (GK 2002/05/24) +
+ +
+ New: Function SparsityPattern::matrix_position is the + inverse function for SparsityPattern::operator(). +
+ (WB 2002/02/13) +
+ +
+ New: Functions SparsityPattern::copy_from and SparseMatrix::copy_from allow to copy a full + matrix into a sparse matrix. +
+ (WB 2002/02/06) +
+

+ + + + +

deal.II

+ +

+ New: The GeometryInfo class now + provides two methods, + unit_cell_vertex and vertices_adjacent_to_line, that reveal + something about the placement and numbering of vertices on the + uni cell. +
+ (GK 2002/05/29) +
+ +
+ New: The GridOut:: + write_dx function is now implemented. + It allows to write the mesh (cells and faces) with some additional + information that may be useful once in a while. +
+ (GK 2002/05/02) +
+ +
+ Fixed: The IteratorState::IteratorState + enum is now called IteratorState::IteratorStates. This works + around a bug in Sun's Forte C++ compilers which can't handle + members of namespaces with the same name as the enclosing + namespace. +
+ (WB 2002/03/20) +
+ +
+ Fixed: In 3d, the function DoFTools::make_hanging_node_constraints + contained an assertion that failed erroneously for finite + elements that do not have degrees of freedom on vertices. This + is now fixed. +
+ (WB 2002/02/21) +
+ +
+ Fixed: TriaAccessor<3,3>::measure + sometimes computed a negative value. This is now fixed. +
+ (WB 2002/02/21) +
+ +
+ New: Finite element family with complete polynomial spaces + for discontinuous Galerkin: FE_DGP +
+ (GK 2002/02/11) +
