+This is the list of changes made between the release of +deal.II version 6.3.0 and that of version 7.0.0. 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. +

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. +

+ +

The public member variable Quadrature::n_quadrature_points has +been removed after being deprecated for nearly three +years. Quadrature.size() replaces its function, and the new version +more naturally preserves consistency. +
+(GK 2010/11/11) +
+ deal.II has had a somewhat quirky directory and library structure for + historical reasons, but this has now changed: All include and source + files are now under the top-level include/ + and source directories. Furthermore, we no longer build a + plethora of libraries but only libdeal_II.g.so (debug + version) and libdeal_II.so (optimized version). In + particular, we no longer build different versions of the library for + different space dimensions. +
+ As a consequence, if your makefile makes any assumption on the + location of deal.II include files or the name of the deal.II library + it will need to be changed. The sample Makefiles have been + updated for this. +
+ (WB 2010/10/25) +
The Polynomials::Lagrange::generate_complete_basis +function has been renamed to Polynomials::generate_complete_Lagrange_basis . +The function was previously the only member of a class, and a static +one on top of that, which did not make much sense. +
+(WB 2010/10/22)
The QGauss2, QGauss3, ..., QGauss7 classes — deprecated +for more than 6 years already — have finally been removed. +You should use code like QGauss@(4) instead. +
+(WB 2010/09/19)
The FE_Nedelec class had previously implemented the lowest order +when the value 1 was passed to the constructor. This has now been +adjusted: the lowest order now results from passing 0, making this +consistent with the FE_RaviartThomas class and following the convention +used in by Brezzi and Raviart (though not in the original paper of +Nedelec). +
+(Markus Bürg 2010/09/14)
The fields DoFHandler::tria and DoFHandler::selected_fe are now +private instead of protected. Inheriting classes can only access them +through DoFHandler::get_tria() and DoFHandler::get_fe(), respectively. +

General

+ +

New: The new step-38 program shows how to discretize and solve + partial differential equations posed on curved manifolds embedded in + higher dimensional spaces. +
+ (Andrea Bonito, M. Sebastian Pauletti, 2011/01/02) +
New: deal.II now has a Qt based graphical user interface to edit + input parameter files for the ParameterHandler class. The executable is + located in lib/bin/dealii_parameter_gui. +
+ (Martin Steigemann, 2010/12/20) +
New: A significant number of classes, primarily in the + base/ subdirectory, now provide the necessary member functions + for serialization through BOOST's serialization library. +
+ (Pradeep Rao, WB, 2010/12/06) +
Fixed: A good number of problems associated with meshes that are + embedded in a higher space dimension (i.e. where dim @< spacedim) + are now fixed. +
+ (Sebastian Pauletti, Andrea Bonito, Luca Heltai, WB, 2010/12/06) +
Updated: The version of the Threading + Building Blocks (TBB) shipped with deal.II has been updated + to release 3.0 Update 3 (Commercially aligned version). +
+ (WB, 2010/11/18) +
New: While 2d and 3d could mostly be handled with the + same code, dimension-independent programming was always a bit + different because the faces of 1d cells (i.e. vertices) did not + have appropriate iterators defined. This has now been changed: + there is now a class TriaAccessor<0,1,spacedim> (and corresponding + DoFAccessor<0,DH>) that allows to write things like + @code + cell->face(0)->boundary_indicator(); + cell->face(1)->at_boundary(); + cell->face(1)->get_dof_indices(...); + @endcode + even if the cell corresponds to a one-dimensional triangulation where + this was not previously possible. +
+ (WB, 2010/11/11) +
+
New: After more than 2 years of work, we have merged a branch on which + we have implemented the functionality necessary to distribute meshes on + hundreds, thousands, or more processors. An overview of the framework + in which this is implemented is presented in the @ref distributed module, + the @ref distributed_paper, as well as in step-40. +
+ (Timo Heister, Martin Kronbichler, Wolfgang Bangerth 2010/10/23) +
+ +
+
New: Documentation of how to handle constraints on degrees of freedom + has been centralized in a new documentation module on @ref constraints. +
+ (WB 2010/09/16) +
+ +
+
Fixed: When using Trilinos and deal.II both with static libraries, + a linker error would occur whenever a program linked both the 2d and + 3d libraries of deal.II. This is now fixed. +
+ (WB 2010/07/23) +
+ +
+
Fixed: On all non-linux platforms, if static libraries were selected + and ./configure was instructed to use Trilinos (which also + was compiled with static libraries), a failure would occur. This should + now be fixed. +
+ (WB 2010/07/23) +
+ +
+
Fixed: The step-33 tutorial program can not be built with GCC versions + 4.5.x. There are in fact two problems, one that pertains to uses of + std::make_pair that don't work any more with the upcoming + C++ 1x standard that GCC 4.5.x already follows, and some in which the + Trilinos package Sacado is incompatible with GCC 4.5.x, at least up to + Trilinos version 10.4.0. While the latter problem can only be fixed in + future Trilinos versions, at least the former problem is solved in step-33. +
+ (WB 2010/07/18) +
+ +
+
Fixed: GCC version 3.4.0 failed to compile the file + deal.II/source/numerics/matrices.cc with + an internal compiler error. This has + now been worked around. +
+ (WB 2010/07/15) +
+ +
+
Fixed: A problem in the Makefiles caused error messages when + building under CygWin. +
+ (GK 2010/07/12) +
+ +
+
Fixed: GCC version 3.3.x failed to compile the files + lac/include/lac/precondition_block.h, + deal.II/source/multigrid/mg_dof_handler.cc and + examples/step-34/step-34.cc. These problems have + now been worked around. +
+ (WB 2010/07/12) +
+ +
+
Fixed: Some older 3.x versions of GCC crashed compiling the functions in + namespace DoFRenumbering::boost. There is now a configuration time test + that checks that the compiler accepts the constructs in question. If the + compiler does not, then these functions are disabled. +
+ (WB 2010/07/01) +
+ +
+
Fixed: Linking with more than one of the deal.II 1d, 2d, or 3d libraries + when using static libraries did not work. This is now fixed. However, due to + GCC bug 10591, GCC versions prior to and including 4.1.x will + still not work. Working with shared libraries was not and is not affected + by this problem. +
+ (WB 2010/07/01) +
+ +
+
Updated: The version of boost + included in the contrib/ directory has been updated + to 1.43.0. +
+ (WB 2010/06/30) +
+ +
+
Fixed: GCC version 4.0.1 had a bug that prevented it from compiling + release 6.3.0 because it apparently had an infinite loop allocating + memory when compiling fe_values.cc in optimized mode. This + problem had been fixed in GCC 4.0.2, but some versions of Mac OS X still use + this GCC version in their Xcode environment. In any case, the code in + deal.II has been changed to avoid this problem. +
+ (WB 2010/06/30) +
+ +
+
Fixed: Configuring with an external BOOST version did not work when + using shared libraries since the test ran in the wrong order with respect + to another configure test. This is now fixed. +
+ (Bradley Froehle 2010/06/29) +
+ +
+
Updated: The conversion tool in contrib/mesh_conversion that + can read CUBIT output and convert it into something that is readable by + deal.II has been updated. +
+ (Jean-Paul Pelteret 2010/06/28) +
+ +
+
+ Fixed: deal.II release 6.3.0 did not compile with Trilinos versions 9.x and + 10.0. This is now fixed. +
+ (Martin Kronbichler, WB 2010/06/28) +
+

+ + + + +

base

+ + +

A static member function Point::unit_vector() has been introduced +to simplify the task of creating a vector in one coordinate direction +independent of the dimension. +
+(GK 2010/11/17) +
There are now Patterns::FileName and Patterns::DirectoryName classes + that can be used to indicate that a given parameter is supposed to be + a file or directory name. +
+ (Martin Steigemann 2010/10/25) +
+ +
New: The ParameterHandler class is now built on the + boost + property_tree library which provides a much better + foundation for extensions. In particular, the description of parameters + can now be exported in XML and JSON formats for processing with external + programs, for example graphical user interfaces. As a consequence of + the re-write, a bug in ParameterHandler::print_parameters_section + was fixed when using the LaTeX output format. +
+ (WB 2010/09/09) +
+ +
Fixed: The ParameterHandler::set() functions allowed to set values that + did not satisfy the pattern given during declaration of the parameter. This + is now fixed: the functions now throw an exception. +
+ (WB 2010/09/09) +
+ +
Fixed: The Patterns::Integer and Patterns::Double classes did + not properly check that a value given matched the pattern because they + ignored text after an initial match. This led to "3.141" and + "3.141..,-RXYZ" to be recognized as valid integers and + double values, respectively. This is now fixed. +
+ (WB 2010/09/08) +
+ +
Fixed: The computation of quadrature points in the QGaussLobatto + class uses a Newton method that was wrongly implemented. While the + results were correct (at least for moderate orders), it required more + iterations than necessary. This is now fixed. +
+ (Andrea Bonito 2010/08/12) +
+ +
Changed: The DataOutBase::write_vtu function now writes data + as 64-bit values, rather than 32-bit values. +
+ (Scott Miller 2010/08/5) +
+ +
New: MappingQ and MappingQEulerian now support order > 1 also in + codimension one. Step-34 has been modified to show how this works. +
+ (Luca Heltai 2010/07/23-27) +
+ +
New: QGaussOneOverR now has a new constructor for arbitrary quadrature + points and not only the vertices of the reference cell. +
+ (Luca Heltai 2010/07/21) +
+

+ + + +

lac

+ +

New: Added a new constructor for PETScWrappers::Vector that takes + an existing PETSc Vec that was created by the user and is only wrapped for + usage. +
+ (TH, 2010/12/03) +
New: When Hypre is available as a sub-package of PETSc, the new class + PETScWrappers::PreconditionBoomerAMG provides the BoomerAMG implementation + of the algebraic multigrid method of the Hypre package as a preconditioner. + This functionality is used, for example, in step-40. +
+ (Timo Heister 2010/11/13) +
New: The class LAPACKFullMatrix now has functions to compute the + singular value decomposition of a matrix and its inverse. +
+ (GK 2010/11/7) +
New: The classes RelaxationBlockSOR and RelaxationBlockSSOR + implement overlapping Schwarz relaxation methods. Additionally, + their base class RelaxationBlock and the helper class BlockList have + been added to the library. +
+ (GK 2010/10/19) +
Improved: The ConstraintMatrix::merge function now takes a second + argument that indicates what should happen if the two objects to be + merged have constraints on the very same degree of freedom. +
+ (WB 2010/09/18) +
Updated: Changes to the SLEPcWrappers to preserve + compatibility with SLEPc version 3.1. Main new updated features are + new solver classes: (i) Power; and (ii) Generalized Davidson. +
+ (Toby D. Young 2010/08/04) +
Fixed: SparseMatrix::precondition_SSOR and + SparseMatrixEZ::precondition_SSOR had a bug, which made the SSOR + method inaccurate for relaxation parameters different from unity. +
+ (GK 2010/07/20) +

+ + + + +

deal.II

+ +

New: The GridTools::transform function used to work only on + meshes that are not refined at all. It now also works on meshes + that have been refined uniformly, though not on adaptively refined + ones. +
+ (WB, 2010/12/20) +
New: When computing errors using + VectorTools::integrate_difference in codimension one problems, if + you specified a norm that requires the computation of the gradients, + you would get in trouble, because on codimension one manifolds we only + have information on the tangential gradient. This is now + fixed, by discarding the normal component of the provided function, + before computing the difference with the finite element function. +
+ (Luca Heltai, 2010/12/05) +
New: The VectorTools::interpolate_boundary_values function can now + also be used to interpolate boundary values on meshes embedded in a higher + dimensional space. +
+ (WB, 2010/11/20) +
Fixed: Triangulation::execute_coarsening_and_refinement misplaced + the new central vertex of a quad in a two-dimensional mesh embedded into + higher dimensional space if said quad was at the boundary of the surface + described by this triangulation. This is now fixed. +
+ (WB, 2010/11/18) +
New: The GridTools::extract_boundary_mesh function can be used to + generate a surface mesh from the boundary of a volume mesh. +
+ (Sebastian Pauletti, 2010/11/15) +
Fixed: For DoF iterators, it was previously possible to write + code like *it1 = *it2, presumably with the intent to + copy the entire cell pointed to on the right hand side onto the cell + pointed to at the left. However, this is not what happens since + iterators are not pointers but only point to accessor classes. The + assignment operator has therefore been removed. +
+ (WB, 2010/11/12) +
New: The GridOut::write_gnuplot function now also works for meshes + that are embedded in a higher + dimensional space (i.e. if the codimension was greater than 1). +
+ (WB, 2010/11/03) +
New: The class hp::FEFaceValues and hp::FESubfaceValues were not + previously available for meshes that were embedded in a higher + dimensional space (i.e. if the codimension was greater than 1). This is + now fixed. As a consequence, the VectorTools::interpolate_boundary_values + function is now also available for such meshes. +
+ (WB, 2010/11/02) +
Fixed: The FEValuesExtractors::Vector class did not work when the dimension + of the domain was not equal to the dimension of the space in which it is + embedded. This is now fixed. +
+ (Sebastian Pauletti, WB, 2010/11/01) +
Fixed: The methods VectorTools::project_boundary_values_curl_conforming + set the boundary values now also H(curl)-conforming, when hanging node + constraints are present. +
+ (Markus Buerg, 2010/10/11) +
Changed: The DataPostprocessor functions now take an additional + argument that indicates the location of an evaluation point. For backward + compatibility, the old function signature still exists so that applications + that overload one of the existing functions continue to work. + The old signature has been deprecated, however, and will be removed in a + future version. +
+ (Scott Miller 2010/10/08) +
Changed: FETools is now a namespace rather than a class with only + static member functions. +
+ (WB 2010/09/25) +
New: FE_DGVector implements discontinuous elements based on + vector valued polynomial spaces. +
+ (GK 2010/09/17) +
+
+ Fixed: The methods VectorTools::interpolate_boundary_values and + VectorTools::project_boundary_values with ConstraintMatrix argument added + inhomogeneities also to DoFs that were already constrained when entering the + call without changing the list of DoFs that those were constrained to. This + leads to wrong results for inhomogeneous constraints in case e.g. + DoFTools::make_hanging_node_constraints was called before. Now, the correct + way for combining hanging node constraints and Dirichlet conditions in one + ConstraintMatrix is to first make the hanging node constraints, and then + interpolate/project the boundary values. The latter operation will then + simply not add any new constraints if a DoF is already constrained. The + same is also true for VectorTools::compute_no_normal_flux_constraints. +
+ (Luca Heltai, Martin Kronbichler, WB 2010/09/16) +
+ +
+
+ Fixed: The method FEValuesViews::Vector::curl aborted the program in 2d under certain + circumstances. This is now fixed. +
+ (Andrea Bonito, WB 2010/09/14) +
+ +
Improved: MeshWorker::loop() now uses WorkStream for multithreading +
+ (GK 2010/09/10) +
+ +
+
+ Fixed: The method FEValuesViews::SymmetricTensor< 2, dim, spacedim >::get_function_divergences + incorrectly calculated the divergence. +
+ (Andrew McBride 2010/09/09) +
+ +
+
+ New: Reimplementation of the parent function in the various DoFCellAccessors so + that one can call the parent function from a DoFIterator and also gets a + DoFIterator returned. +
+ (Markus Buerg 2010/08/30) +
+ +
+
+ New: FETools::compute_embedding_matrices now computes the embedding matrix + for all refinement cases in parallel. +
+ (Markus Buerg 2010/08/26) +
+ +
+
+ New: There is now a function CellAccessor::parent so that one can do + cell-@>parent() +
+ (Markus Buerg 2010/08/26) +
+ +
+
+ Improved: DoFHandler has a default constructor, so that it can be used in containers. +
+ (GK 2010/08/16) +
+ +
+
+ New: The functions VectorTools::project_boundary_values_curl_conforming + are added. They can compute Dirichlet boundary conditions for Nedelec + elements. +
+ (Markus Buerg 2010/08/13) +
+ +
+
+ Fixed: The function FEValuesViews::Vector::get_function_curls produced + wrong results in some cases, because it erased the given vector first. + This is now fixed. +
+ (Markus Buerg 2010/08/13) +
+ +
+
+ New: Ability to project second-order SymmetricTensor and first-order Tensor objects from the quadrature points to the support points of the cell using FETools::compute_projection_from_quadrature_points +
+ (Andrew McBride 2010/07/29) +
+ +
+
+ Fixed: In some rather pathological cases, the function + Triangulation::prepare_coarsening_and_refinement (which is called from + Triangulation::execute_coarsening_and_refinement) could take very long + if the flag Triangulation::eliminate_unrefined_islands was given in + the mesh smoothing flags upon construction of the triangulation. This is + now fixed. +
+ (WB 2010/07/27) +
+ +
New: Brezzi-Douglas-Marini elements of arbitrary order in FE_BDM. +
+ (GK 2010/07/19) +
+ +
+
+ Fixed: The FEValues::get_cell() function was unusable from user code + since its implementation used a class that was only forward declared + and not visible at the point of instantiations in user code. This is now + fixed. +
+ (WB 2010/07/16) +
+ +
+
New: The multilevel matrices for continuous elements + can be built with the MeshWorker now. +
+ (Bärbel Janssen 2010/07/01) +
+
+ Fixed: On some systems and compilers, the library could not be compiled + because of a duplicate symbol in MeshWorker::LocalResults. + This is now fixed. +
+ (WB 2010/06/28) +
+ +
+
+ Fixed: The output of the function + FE_Q::adjust_quad_dof_index_for_face_orientation + was wrong in 3d for polynomial orders of three or greater. This is now + fixed. +

Fixed: GCC version 3.4.0 failed to compile the file - deal.II/source/numerics/matrices.cc with - an internal compiler error. This has - now been worked around. -
- (WB 2010/07/15) -
- -
-
Fixed: A problem in the Makefiles caused error messages when - building under CygWin. -
- (GK 2010/07/12) -
- -
-
Fixed: GCC version 3.3.x failed to compile the files - lac/include/lac/precondition_block.h, - deal.II/source/multigrid/mg_dof_handler.cc and - examples/step-34/step-34.cc. These problems have - now been worked around. -
- (WB 2010/07/12) -
- -
-
Fixed: Some older 3.x versions of GCC crashed compiling the functions in - namespace DoFRenumbering::boost. There is now a configuration time test - that checks that the compiler accepts the constructs in question. If the - compiler does not, then these functions are disabled. -
- (WB 2010/07/01) -
- -
-
Fixed: Linking with more than one of the deal.II 1d, 2d, or 3d libraries - when using static libraries did not work. This is now fixed. However, due to - GCC bug 10591, GCC versions prior to and including 4.1.x will - still not work. Working with shared libraries was not and is not affected - by this problem. -
- (WB 2010/07/01) -
- -
-
Updated: The version of boost - included in the contrib/ directory has been updated - to 1.43.0. -
- (WB 2010/06/30) -
- -
-
Fixed: GCC version 4.0.1 had a bug that prevented it from compiling - release 6.3.0 because it apparently had an infinite loop allocating - memory when compiling fe_values.cc in optimized mode. This - problem had been fixed in GCC 4.0.2, but some versions of Mac OS X still use - this GCC version in their Xcode environment. In any case, the code in - deal.II has been changed to avoid this problem. -
- (WB 2010/06/30) -
- -
-
Fixed: Configuring with an external BOOST version did not work when - using shared libraries since the test ran in the wrong order with respect - to another configure test. This is now fixed. -
- (Bradley Froehle 2010/06/29) -
- -
-
Updated: The conversion tool in contrib/mesh_conversion that - can read CUBIT output and convert it into something that is readable by - deal.II has been updated. -
- (Jean-Paul Pelteret 2010/06/28) -
- -
-
- Fixed: deal.II release 6.3.0 did not compile with Trilinos versions 9.x and - 10.0. This is now fixed. -

Specific improvements

A static member function Point::unit_vector() has been introduced -to simplify the task of creating a vector in one coordinate direction -independent of the dimension. -
-(GK 2010/11/17) -
There are now Patterns::FileName and Patterns::DirectoryName classes - that can be used to indicate that a given parameter is supposed to be - a file or directory name. -
- (Martin Steigemann 2010/10/25) -
- -
New: The ParameterHandler class is now built on the - boost - property_tree library which provides a much better - foundation for extensions. In particular, the description of parameters - can now be exported in XML and JSON formats for processing with external - programs, for example graphical user interfaces. As a consequence of - the re-write, a bug in ParameterHandler::print_parameters_section - was fixed when using the LaTeX output format. -
- (WB 2010/09/09) -
- -
Fixed: The ParameterHandler::set() functions allowed to set values that - did not satisfy the pattern given during declaration of the parameter. This - is now fixed: the functions now throw an exception. -
- (WB 2010/09/09) -
- -
Fixed: The Patterns::Integer and Patterns::Double classes did - not properly check that a value given matched the pattern because they - ignored text after an initial match. This led to "3.141" and - "3.141..,-RXYZ" to be recognized as valid integers and - double values, respectively. This is now fixed. -
- (WB 2010/09/08) -
- -
Fixed: The computation of quadrature points in the QGaussLobatto - class uses a Newton method that was wrongly implemented. While the - results were correct (at least for moderate orders), it required more - iterations than necessary. This is now fixed. -
- (Andrea Bonito 2010/08/12) -
- -
Changed: The DataOutBase::write_vtu function now writes data - as 64-bit values, rather than 32-bit values. -
- (Scott Miller 2010/08/5) -
- -
New: MappingQ and MappingQEulerian now support order > 1 also in - codimension one. Step-34 has been modified to show how this works. -
- (Luca Heltai 2010/07/23-27) -
- -
New: QGaussOneOverR now has a new constructor for arbitrary quadrature - points and not only the vertices of the reference cell. -
- (Luca Heltai 2010/07/21) -

New: Added a new constructor for PETScWrappers::Vector that takes - an existing PETSc Vec that was created by the user and is only wrapped for - usage. -
- (TH, 2010/12/03) -
New: When Hypre is available as a sub-package of PETSc, the new class - PETScWrappers::PreconditionBoomerAMG provides the BoomerAMG implementation - of the algebraic multigrid method of the Hypre package as a preconditioner. - This functionality is used, for example, in step-40. -
- (Timo Heister 2010/11/13) -
New: The class LAPACKFullMatrix now has functions to compute the - singular value decomposition of a matrix and its inverse. -
- (GK 2010/11/7) -
New: The classes RelaxationBlockSOR and RelaxationBlockSSOR - implement overlapping Schwarz relaxation methods. Additionally, - their base class RelaxationBlock and the helper class BlockList have - been added to the library. -
- (GK 2010/10/19) -
Improved: The ConstraintMatrix::merge function now takes a second - argument that indicates what should happen if the two objects to be - merged have constraints on the very same degree of freedom. -
- (WB 2010/09/18) -
Updated: Changes to the SLEPcWrappers to preserve - compatibility with SLEPc version 3.1. Main new updated features are - new solver classes: (i) Power; and (ii) Generalized Davidson. -
- (Toby D. Young 2010/08/04) -
Fixed: SparseMatrix::precondition_SSOR and - SparseMatrixEZ::precondition_SSOR had a bug, which made the SSOR - method inaccurate for relaxation parameters different from unity. -
- (GK 2010/07/20) -

New: The GridTools::transform function used to work only on - meshes that are not refined at all. It now also works on meshes - that have been refined uniformly, though not on adaptively refined - ones. -
- (WB, 2010/12/20) -
New: When computing errors using - VectorTools::integrate_difference in codimension one problems, if - you specified a norm that requires the computation of the gradients, - you would get in trouble, because on codimension one manifolds we only - have information on the tangential gradient. This is now - fixed, by discarding the normal component of the provided function, - before computing the difference with the finite element function. -
- (Luca Heltai, 2010/12/05) -
New: The VectorTools::interpolate_boundary_values function can now - also be used to interpolate boundary values on meshes embedded in a higher - dimensional space. -
- (WB, 2010/11/20) -
Fixed: Triangulation::execute_coarsening_and_refinement misplaced - the new central vertex of a quad in a two-dimensional mesh embedded into - higher dimensional space if said quad was at the boundary of the surface - described by this triangulation. This is now fixed. -
- (WB, 2010/11/18) -
New: The GridTools::extract_boundary_mesh function can be used to - generate a surface mesh from the boundary of a volume mesh. -
- (Sebastian Pauletti, 2010/11/15) -
Fixed: For DoF iterators, it was previously possible to write - code like *it1 = *it2, presumably with the intent to - copy the entire cell pointed to on the right hand side onto the cell - pointed to at the left. However, this is not what happens since - iterators are not pointers but only point to accessor classes. The - assignment operator has therefore been removed. -
- (WB, 2010/11/12) -
New: The GridOut::write_gnuplot function now also works for meshes - that are embedded in a higher - dimensional space (i.e. if the codimension was greater than 1). -
- (WB, 2010/11/03) -
New: The class hp::FEFaceValues and hp::FESubfaceValues were not - previously available for meshes that were embedded in a higher - dimensional space (i.e. if the codimension was greater than 1). This is - now fixed. As a consequence, the VectorTools::interpolate_boundary_values - function is now also available for such meshes. -
- (WB, 2010/11/02) -
Fixed: The FEValuesExtractors::Vector class did not work when the dimension - of the domain was not equal to the dimension of the space in which it is - embedded. This is now fixed. -
- (Sebastian Pauletti, WB, 2010/11/01) -
Fixed: The methods VectorTools::project_boundary_values_curl_conforming - set the boundary values now also H(curl)-conforming, when hanging node - constraints are present. -
- (Markus Buerg, 2010/10/11) -
Changed: The DataPostprocessor functions now take an additional - argument that indicates the location of an evaluation point. For backward - compatibility, the old function signature still exists so that applications - that overload one of the existing functions continue to work. - The old signature has been deprecated, however, and will be removed in a - future version. -
- (Scott Miller 2010/10/08) -
Changed: FETools is now a namespace rather than a class with only - static member functions. -
- (WB 2010/09/25) -
New: FE_DGVector implements discontinuous elements based on - vector valued polynomial spaces. -
- (GK 2010/09/17) -
-
- Fixed: The methods VectorTools::interpolate_boundary_values and - VectorTools::project_boundary_values with ConstraintMatrix argument added - inhomogeneities also to DoFs that were already constrained when entering the - call without changing the list of DoFs that those were constrained to. This - leads to wrong results for inhomogeneous constraints in case e.g. - DoFTools::make_hanging_node_constraints was called before. Now, the correct - way for combining hanging node constraints and Dirichlet conditions in one - ConstraintMatrix is to first make the hanging node constraints, and then - interpolate/project the boundary values. The latter operation will then - simply not add any new constraints if a DoF is already constrained. The - same is also true for VectorTools::compute_no_normal_flux_constraints. -
- (Luca Heltai, Martin Kronbichler, WB 2010/09/16) -
- -
-
- Fixed: The method FEValuesViews::Vector::curl aborted the program in 2d under certain - circumstances. This is now fixed. -
- (Andrea Bonito, WB 2010/09/14) -
- -
Improved: MeshWorker::loop() now uses WorkStream for multithreading -
- (GK 2010/09/10) -
- -
-
- Fixed: The method FEValuesViews::SymmetricTensor< 2, dim, spacedim >::get_function_divergences - incorrectly calculated the divergence. -
- (Andrew McBride 2010/09/09) -
- -
-
- New: Reimplementation of the parent function in the various DoFCellAccessors so - that one can call the parent function from a DoFIterator and also gets a - DoFIterator returned. -
- (Markus Buerg 2010/08/30) -
- -
-
- New: FETools::compute_embedding_matrices now computes the embedding matrix - for all refinement cases in parallel. -
- (Markus Buerg 2010/08/26) -
- -
-
- New: There is now a function CellAccessor::parent so that one can do - cell-@>parent() -
- (Markus Buerg 2010/08/26) -
- -
-
- Improved: DoFHandler has a default constructor, so that it can be used in containers. -
- (GK 2010/08/16) -
- -
-
- New: The functions VectorTools::project_boundary_values_curl_conforming - are added. They can compute Dirichlet boundary conditions for Nedelec - elements. -
- (Markus Buerg 2010/08/13) -
- -
-
- Fixed: The function FEValuesViews::Vector::get_function_curls produced - wrong results in some cases, because it erased the given vector first. - This is now fixed. -
- (Markus Buerg 2010/08/13) -
- -
-
- New: Ability to project second-order SymmetricTensor and first-order Tensor objects from the quadrature points to the support points of the cell using FETools::compute_projection_from_quadrature_points -
- (Andrew McBride 2010/07/29) -
- -
-
- Fixed: In some rather pathological cases, the function - Triangulation::prepare_coarsening_and_refinement (which is called from - Triangulation::execute_coarsening_and_refinement) could take very long - if the flag Triangulation::eliminate_unrefined_islands was given in - the mesh smoothing flags upon construction of the triangulation. This is - now fixed. -
- (WB 2010/07/27) -
- -
New: Brezzi-Douglas-Marini elements of arbitrary order in FE_BDM. -
- (GK 2010/07/19) -
- -
-
- Fixed: The FEValues::get_cell() function was unusable from user code - since its implementation used a class that was only forward declared - and not visible at the point of instantiations in user code. This is now - fixed. -
- (WB 2010/07/16) -
- -
-
New: The multilevel matrices for continuous elements - can be built with the MeshWorker now. -
- (Bärbel Janssen 2010/07/01) -
-
- Fixed: On some systems and compilers, the library could not be compiled - because of a duplicate symbol in MeshWorker::LocalResults. - This is now fixed. -
- (WB 2010/06/28) -
-
-
- Fixed: The output of the function - FE_Q::adjust_quad_dof_index_for_face_orientation - was wrong in 3d for polynomial orders of three or greater. This is now - fixed. -
