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. Deprecated: The DataOutInterface::write_pvd_record() and - DataOutInterface::write_visit_record() functions were actually - independent of any kind of data being written. As a consequence, - they did not depend on the state of the DataOutInterface object - to which they belonged (or any object of a derived class). Such - functions typically reside in the DataOutBase namespace instead - where they have now been moved. The functions in DataOutInterface - are now deprecated. -
    - (Wolfgang Bangerth, 2016/12/03) -
    2. - -
  2. Changed: VectorTools::create_right_hand_side and - VectorTools::create_boundary_right_hand_side now take an additional template - parameter VectorType. -
    - (Daniel Arndt, 2016/10/25) -
    3. - -
  3. Deprecated: ParameterHandler::read_input, - ParameterHandler::read_input_from_xml, and - ParameterHandler::read_input_from_string are now deprecated in favor of - ParameterHandler::parse_input, ParameterHandler::parse_input_from_xml, and - ParameterHandler::parse_input_from_string. These new functions throw - exceptions to indicate failure instead of using return codes. -
    - (David Wells, 2016/09/15) -
    4. - -
  4. Deprecated: MGCoarseGridLACIteration got deprecated in favor of - MGCoarseGridIterativeSolver. -
    - (Timo Heister, 2016/09/14) -
    5. - -
  5. Changed: The template parameter order in many VectorTools functions is now - different; this was done so that the order is the same across similar functions. - This will only effect code that explicitly specifies template parameters for - overloaded VectorTools functions (no known deal.II-based projects do this). -
    - (David Wells, 2016/09/06) -
    6. - -
  6. New: deal.II now requires at least BOOST version 1.56, rather than the - previous minimal version of 1.54. This is because 1.54 does not support - serializing objects of type std::unique_ptr if C++11 is used, but we now - use such objects in a variety of places in classes that can be serialized. - BOOST 1.56, on the other hand, supports this. deal.II bundles BOOST 1.62 - for cases where no or no sufficiently new version of BOOST is found on - a system. -
    - (Wolfgang Bangerth, 2016/08/22) -
    7. - -
  7. Removed: Deprecated classes CompressedSparsityPattern, - CompressedSimpleSparsityPattern, CompressedSetSparsityPattern, and their - block variants got removed. -
    - (Timo Heister, 2016/08/13) -
    8. - -
  8. Deprecated: MGLevelObject::clear() deprecated in favor of - MGLevelObject::clear_elements() due to clear() being inconsistent with - behavior of other container objects. -
    - (Jonathan Robey, 2016/08/08) -
    9. - -
  9. Changed: Several operators from LocalIntegrators::Divergence got moved - to LocalIntegrators::GradDiv and the never used/tested - LocalIntegrators::Divergence::grad_div() function was removed. -
    - (Timo Heister, Guido Kanschat, 2016/08/02) -
    10. - -
  10. Changed: DoFTools::make_cell_patches() only accepts block lists of type - SparsityPattern. The reason is that it has to initialize the size of the - pattern on distributed triangulations by computing the number of locally - owned cells. Initialization differs between sparsity pattern classes, so no - generic function would be possible. On the other hand, the block list is an - object, which only extends over locally owned grid cells and its size can be - determined efficiently upon initialization. Therefore, SparsityPattern is a - good choice here. -
    - At the same time, we changed the dof handler template to the type DoFHandler, - since hp::DoFHandler requires a different setup of the SparsityPattern. -
    - (Guido Kanschat, 2016/08/02) -
    11. - -
  11. Changed: The conversion constructors of class Vector from the - PETScWrappers::Vector, PETScWrappers::MPI::Vector, - TrilinosWrappers::Vector, and TrilinosWrappers::MPI::Vector classes - are now marked as explicit, i.e., they will no longer - allow implicit, silent conversions. Such conversions lead to awkward - errors that are hard to debug, and in cases where they are necessary, - are best described in code through explicit casts. -
    - (Wolfgang Bangerth, 2016/06/25) -
    12. - -
  12. Changed: The deal.II distributed vector classes do now derive from - LinearAlgebra::VectorSpaceVector and have been moved to the - LinearAlgebra::distributed namespace. In the definition of the new - interfaces, several old vector functions have been marked as deprecated. The - methods operator==, operator!=, and - is_non_negative have been removed from the new interface. -
    - (Martin Kronbichler, 2016/06/15) -
    13. - -
  13. Changed: The Triangulation::Signals::clear signal is now triggered - before, not after the internal data structures of the - triangulation are destroyed. This allows functions attached to the signal to - save information associated with the triangulation. -
    - (Wolfgang Bangerth, 2016/06/07) -
    14. - -
  14. Changed: deal.II used to create template instantiations for scalar - types double, float, and long double. Since - long double is rarely used and the additional precision does - usually not pay off because most of the other arithmetics in deal.II are - only done using double variables, it is not instantiated by default - any more. This reduces the library size by up to 20 percent. In case you - need instantiations of certain methods using long double data - structures and get linker errors stating undefined symbols involving - long double, include the respective .templates.h file(s) - with the code definitions. See the section on @ref Instantiations in the - manual for further information. -
    - (Martin Kronbichler, 2016/04/26) -
    15. - -
  15. Changed: FlatManifold takes as argument a periodicity option. This - used to be a Point, but it should have been a Tensor<1,dim>. This - is now changed. -
    - (Luca Heltai, 2016/04/09) -
    16. - -
  16. Changed: The default nodal point distribution of FE_Q, FE_DGQ, - FE_Q_DG0, FE_Q_Bubbles, and FE_TraceQ has been changed from equidistant - points to the node points of the corresponding Gauss-Lobatto quadrature - formula. For degrees one and two, the Gauss-Lobatto quadrature is - equidistant and thus the unit support points are as before. However, the - Gauss-Lobatto points are more dense towards the element boundaries at higher - degrees. This gives well-conditioned interpolation at arbitrary orders and - much more stable computations. While these node distribution was available - before, it was not very visible and often lead to misunderstandings by - inexperienced users. Most codes will not be affected by this change, even - those using cubic and higher degree polynomials, apart from slightly - different (better) interpolation behavior and different entries in solution - vectors. If you explicitly need equidistant points, use the constructors - FE_Q(QIterated<1>(QTrapez<1>(),degree)) or - FE_DGQArbitraryNodes(QIterated<1>(QTrapez<1>(),degree)). -
    - (Martin Kronbichler, 2016/04/05) -
    17. - -
  17. Removed: Support for the legacy Make.global_options - file has been removed. -
    - (Matthias Maier, 2016/03/17) -
    18. - -
  18. Removed: Functions with names containing boundary_indicator - have been removed. They had previously already been deprecated, and replaced - by functions containing the string boundary_id instead, to keep - with the style used for material_id, subdomain_id, - etc. -
    - (Wolfgang Bangerth, 2016/02/28) -
    19. - -
  19. Changed: Many functions in VectorTools and MatrixTools now require - matching data types between vectors, matrices, and Function arguments. -
    - (Denis Davydov, 2016/02/27) -
    20. - -
  20. Changed: ConstraintMatrix::distribute_local_to_global() and numerous - functions in VectorTools namespace now require matching data types. - This is done to correctly handle complex-valued case. -
    - (Denis Davydov, 2016/02/22) -

General

- -
    - -
  1. New: Implemented some standard tensor definitions for elasticity in - Physics::Elasticity::StandardTensors. Within the newly implemented - Physics::Elasticity::Kinematics namespace are some standard - definitions of kinematic quantities commonly used in elasticity. -
    - (Jean-Paul Pelteret, Andrew McBride, 2016/12/05) -
    2. - -
  2. New: The Physics::Transformations namespace defines a number of operations - that can be used to push forward and pull back quantities to and from different - body configurations. -
    - (Jean-Paul Pelteret, Andrew McBride, 2016/12/05) -
    3. - -
  3. New: The Physics namespace is dedicated to defining useful - functions and other quantities that are regularly used in the implementation - of classical (multi-)physics problems. -
    - (Jean-Paul Pelteret, 2016/12/05) -
    4. - -
  4. Improved: The step-37 tutorial program now shows the matrix-free multigrid - solver based on MPI parallelization rather than only a serial version. - Moreover, support for adaptively refined meshes has been added. -
    - (Martin Kronbichler, 2016/11/23) -
    5. - -
  5. Improved: the error codes for all MPI functions are now checked and, if the - MPI function failed for any reason, an exception with a helpful message is - thrown. -
    - (David Wells, 2016/11/09) -
    6. - -
  6. - Fixed: We have run the PVS static analysis checker on the entire code base, - to see what possible problems it uncovers (see - https://github.com/dealii/dealii/issues/3342). With the exception of - a few false positives, several dozen issues (mostly uninitialized - variables) were fixed. -
    - (Konstantin Ladutenko and many others, 2016/11/08) -
    7. - -
  7. Improved: The way DataPostprocessor receives its input has been updated. -
    - In the past, the two functions we use to postprocess data got lists of arguments - for the solution, its derivatives, the evaluation points, and normal vectors. - This is not flexible enough: We can not easily add other information that - we have needed in the past or that users have requested, such as a pointer - to the cell we're currently on, or the material-id of the cell. -
    - Rather than adding each possible argument anyone may want to use - individually to the list of the postprocessor function arguments, the - existing functions have been deprecated in favor of a new set of - functions DataPostprocessor::evaluate_scalar_field() and - DataPostprocessor::evaluate_vector_field() that - take a reference to a structure that contains these individual pieces - of information. We can extend the members of these structures without - backward compatibility issues because the functions still get a - reference to the same structure, we just grow the structure - itself. Functions that never used the new members of the structure - will continue to work as they always did. -
    - (Wolfgang Bangerth, 2016/10/31) -
    8. - -
  8. Improved: The code in class GridReordering has been rewritten from - scratch. It now follows the algorithm described in the paper by - Agelek, Anderson, Bangerth and Barth mentioned in the documentation - of that class. -
    - (Wolfgang Bangerth, 2016/10/28) -
    9. - -
  9. Improved: deal.II now bundles a subset of BOOST 1.62 instead of a subset - of BOOST 1.56. -
    - (David Wells, 2016/10/20) -
    10. - -
  10. New: Add a new FiniteElement class, FE_P1NC, to implement the scalar - version of the P1 nonconforming finite element which is a piecewise linear - element on quadrilaterals in 2d. -
    - (Jaeryun Yim, 2016/10/01) -
    11. - -
  11. New: FE_Enriched finite element class implements the partition of unitity - method which allows to enrich the finite element space based on a priori - knowledge about solution. -
    - (Denis Davydov, 2016/09/28) -
    12. - -
  12. New: The Tensor class has two new functions implemented, namely those - that return its Tensor::adjoint() and Tensor::cofactor(). -
    - (Jean-Paul Pelteret, 2016/09/25) -
    13. - -
  13. Improved: The doxygen documentation now contains nicely formatted - boxes containing the text message of each exception. Several messages - haven been clarified and improved. -
    - (Timo Heister, 2016/09/06) -
    14. - -
  14. New: There are 6 new video lectures that explain the - basics of Linux and the command line, how mesh refinement works, and some - more complicated time stepping schemes. - (@dealiiVideoLectureSeeAlso{2.9,2.91,17.25,17.5,17.75,30.25}) -
    - (Wolfgang Bangerth, 2016/08/19) -
    15. - -
  15. New: deal.II no longer uses features of the C++ language that - were deprecated with C++11, C++14, or that are scheduled to be - deprecated for C++17. -
    - (David Wells, Jonathan Robey, Wolfgang Bangerth, 2016/08/11) -
    16. - -
  16. - New: Added Python bindings to generate and manipulate a Triangulation from - Python. The Triangulation generated in Python can be saved and later, loaded - inside a C++ code. -
    - (Bruno Turcksin, 2016/08/03) -
    17. - -
  17. - Improved: A few of the introductory examples (steps five through eight) no - longer use the Function class; they use plain functions instead. -
    - (David Wells, 2016/07/25) -
    18. - -
  18. Improved: The build system now checks for usable compiler/linker - flags during various stages of the configure run. This should catch the - majority of issues by user supplied flags/libraries and unusable final - link interfaces before we actually proceed to compile the library. -
    - (Matthias Maier, 2016/07/13) -
    19. - -
  19. Improved: The testsuite now supports fine grained feature constraints - of the form test.with_[feature]_with_[...]=true corresponding - to variables DEAL_II__WITH_[...] exported to - deal.IIConfig.cmake. -
    - (Matthias Maier, 2016/07/11) -
    20. - -
  20. New: The library is now compatible with PETSc 3.7.0. Part of this change - included adding a new header, petsc_compatibility.h, which provides - some version-independent functions for using common PETSc functions. -
    - (David Wells, 2016/07/07) -
    21. - -
  21. Refactored: The contrib/ directory has been cleaned up and the - Parameter GUI has be reloacted into its own repository: - https://github.com/dealii/parameter_gui -
    - (Matthias Maier, Timo Heister, 2016/07/06) -
    22. - -
  22. New: Add new classes to expand a scalar finite element solution into - the orthogonal bases FESeries::Fourier and FESeries::Legendre. Also - provide auxiliary functions to calculate norms of subsets of expansion - coefficients FESeries::process_coefficients and linear regression - FESeries::linear_regression. Update step-27 to use this namespace to drive - the hp-adaptive FEM solution process. -
    - (Denis Davydov, 2016/06/23) -
    23. - -
  23. New: The tutorial step-55 shows how to solve the Stokes system - in parallel with PETSc or Trilinos. -
    - (Timo Heister, 2016/06/17) -
    24. - -
  24. New: The tutorial step-56 demonstrates Geometric Multigrid for the - Stokes equations. -
    - (Ryan Grove, Timo Heister, 2016/06/01) -
    25. - -
  25. Improved: The step-44 tutorial now uses the new CellDataStorage class to - store and retrieve local quadrature point data. An alternative approach to - solving the linear system using the LinearOperator class has been implemented. -
    - (Jean-Paul Pelteret, 2016/05/20) -
    26. - -
  26. New: Add a collection of classes to manage user's quadrature point data: - CellDataStorage, TransferableQuadraturePointData and - parallel::distributed::ContinuousQuadratureDataTransfer. - The implementation of CellDataStorage is flexible to support different types of - data object at different cells. parallel::distributed::ContinuousQuadratureDataTransfer - provides a convenient interface to transfer quadrature point data between cells - of parallel::distributed::Triangulation. -
    - (Denis Davydov, Jean-Paul Pelteret, 2016/04/30) -
    27. - -
  27. New: Added an interface to the GNU Scientific Library. Also introduce a - cubic spline interpolation function Functions::CSpline. -
    - (Denis Davydov, 2016/04/28) -
    28. - -
  28. New: Added move operations to BlockIndices, BlockVectorBase and - BlockVector; Vector move operations nullify old object instead of - using swap. -
    - (Daniel Shapero, 2016/04/13) -
    29. - -
  29. New: Manifold objects were previously only used to compute the - locations of individual new points on a manifold. Now, they are also - used to compute tangent vectors (via Manifold::get_tangent_vector()), and this - functionality provides the basis for computing normal vectors to manifolds - as well. -
    - In many cases, tangent vectors can be computed quite easily if the - manifold has a functional description, i.e., if it can be - represented via the ChartManifold class. In those cases, it is only - necessary to overload the ChartManifold::push_forward_gradient() - function that computes the derivatives of the push forward operation. -
    - (Luca Heltai, Wolfgang Bangerth, 2016/04/08) -
    30. - -
  30. New: Added a new Mapping class, MappingManifold, to use exact - geometrical information extracted from the Manifold description instead - of a polynomial approximation when computing transformations from the - reference to the real cell. This class allows the computation of - quadrature points, tangent vectors, and normal vectors which are exact - with respect to the geometrical description, and it uses the underlying - Manifold objects of the Triangulation. MappingManifold coincides with - MappingQ1 for the FlatManifold descriptor. -
    - (Luca Heltai, 2016/04/09) -
    31. - -
  31. New: Added indent target to indent all headers and source - files. Now you can do make (or ninja) indent inside the build - directory. -
    - (Alberto Sartori, 2016/03/02) -
    32. -

Specific improvements

- -
    -
  1. New: The ArrayView class now has a default constructor that creates - an invalid object. -
    - (Wolfgang Bangerth, 2016/12/08) -
    2. - -
  2. Fixed: ArrayView objects to empty views could not be copied. - This is now fixed. -
    - (Wolfgang Bangerth, 2016/12/07) -
    3. - -
  3. Improved: The run time for the method hp::DoFHandler::distribute_dofs was - quadratic in the total number of dofs for some grids. This has been fixed. -
    - (David Wells, 2016/12/07) -
    4. - -
  4. New: The inverse of a rank-2 SymmetricTensor can now be directly computed - with SymmetricTensor::invert() instead of having to use the - Tensor::invert() function. -
    - (Jean-Paul Pelteret, 2016/12/07) -
    5. - -
  5. Changed: To improve readability, TimerOutput::print_summary() - now simply outputs "0%" if a particular section's time requires - less than 0.1 per cent of the overall run time. -
    - (Wolfgang Bangerth, 2016/12/03) -
    6. - -
  6. Improved: The trait class has_vmult_add in linear_operators.h - has been restricted to test if there is a vmult_add and a Tvmult_add - method that takes two arguments. This check now also works with - ICC 13 and ICC 14. -
    - (Daniel Arndt, 2016/11/25) -
    7. - -
  7. Fixed: DataOut::build_patches() ignored a higher order - or Eulerian mapping if no data had previously been attached - via DataOut::add_data_vector(), i.e., if all that was to be output - is the mesh itself. This is now fixed. -
    - (Wolfgang Bangerth, 2016/11/15) -
    8. - -
  8. Fixed: Calling MappingQ::clone() did not copy the - use_mapping_q_on_all_cells flag that this - mapping class gets passed to its constructor. This leads - to wrong results if you wanted to use curved cells on - interior cells and if such an object was used inside an - hp::MappingCollection, for example. There are, in addition, - several places in the library where one would pass a mapping, - and the library would clone it into a member of such a collection, - and these would also yield wrong results. An example is the use - of DataOut::build_patches with a mapping that had this flag set - upon construction. -
    - (Sebastian Gonzalez-Pintor, Wolfgang Bangerth, 2016/11/15) -
    9. - -
  9. Fixed: Objects of type TrilinosWrappers::SparsityPattern::const_iterator - were entirely unusable due to a bug. This is now fixed. -
    - (Wolfgang Bangerth, 2016/11/15) -
    10. - -
  10. Fixed: There was a memory leak if a previously used SparsityPattern - object was re-used by reading from a serialization archive via - SparsityPattern::load(). This is now fixed. -
    - (Wolfgang Bangerth, 2016/11/10) -
    11. - -
  11. New: Add PArpackSolver::reinit(const VectorType &distributed_vector) to - initialize internal data structures based on a vector. This makes PArpack - usable with MatrixFree operators. -
    - (Denis Davydov, 2016/10/31) -
    12. - -
  12. New: VectorTools::project can be used for parallel Triangulations in - specific cases. -
    - (Daniel Arndt, 2016/10/30) -
    13. - -
  13. New: Add MatrixFreeOperators::LaplaceOperator representing a Laplace matrix. -
    - (Denis Davydov, 2016/10/30) -
    14. - -
  14. New: Add VectorTools::project() to do L2 projection - of scalar-valued quadrature point data in parallel. -
    - (Denis Davydov, 2016/10/28) -
    15. - -
  15. Fixed: Increased precision of timesteps in DataOutInterface::write_pvd_record(). -
    - (Rajat Arora, 2016/10/29) -
    16. - -
  16. New: Add MatrixFreeOperators::MassOperator representing a mass matrix. -
    - (Daniel Arndt, 2016/10/27) -
    17. - -
  17. New: There is a new class DiagonalMatrix which represents a diagonal - matrix via a vector. This is useful for representing Jacobi preconditioners - with matrix-free methods. -
    - (Martin Kronbichler, 2016/10/27) -
    18. - -
  18. New: The class PreconditionChebyshev now offers a third template - parameter PreconditionerType that is passed to the preconditioner setup via - AdditionalData::preconditioner. This allows using other preconditioners than - the default (and previous) selection of a point-Jacobi preconditioner. -
    - (Martin Kronbichler, 2016/10/27) -
    19. - -
  19. >New: VectorTools::create_right_hand_side can be used for parallel - Triangulations and homogeneous constraints using a ConstraintMatrix. -
    - (Daniel Arndt, 2016/10/25) -
    20. - -
  20. Fixed: GridIn::read_vtk() had off-by-one errors in reading face - boundary indicators from VTK files. Consequently, not all boundary indicators - were correctly set. -
    - (Mayank Sabharwal, Wolfgang Bangerth, 2016/10/25) -
    21. - -
  21. New: Add ArpackSolver::set_shift() to set the shift value in spectral - transformation. -
    - (Denis Davydov, 2016/10/25) -
    22. - -
  22. New: PreconditionChebyshev now offers a PreconditionChebyshev::step() - and PreconditionChebyshev::Tstep() methods for usage in relaxation smoothers. -
    - (Martin Kronbichler, 2016/10/21) -
    23. - -
  23. Fixed: GridIn::read_vtk() accidentally only read material ids of - input cells correctly if the file listed them as integers. If they were - listed them as floating point numbers, then unpredictable numbers were used. -
    - (Wolfgang Bangerth, 2016/10/20) -
    24. - -
  24. New: Add a base class for matrix-free operators MatrixFreeOperators::Base. -
    - (Denis Davydov, 2016/10/16) -
    25. - -
  25. New: There is now a function FEEvaluation::JxW() to return the Jacobian - determinant times the quadrature weight in the matrix-free evaluation - routines similary to FEValues. -
    - (Martin Kronbichler, 2016/10/14) -
    26. - -
  26. Fixed: GridGenerator::hyper_cube_slit() with colorized set to - true is now working correctly. -
    - (Timo Heister, 2016/10/04) -

    - (Daniel Arndt, 2016/09/16) -
    34. - -
  34. Improved: The multigrid V-cycle has been rewritten for performance on - large-scale machines. Rather than transferring parts of the defect - immediately to all coarser levels with a complexity of O(n_levels) global - communication steps per V-cycle, we now transfer the full defect once to the - next coarser level only, resulting in crossing all processors only once. -
    - (Martin Kronbichler, 2016/09/16) -
    35. - -
  35. Fixed: The Multigrid W-cycle and F-cycle have been fixed (for uniform - grids). -

    47. - -
  47. Improved: SparsityPattern::copy_from() copying from a - DynamicSparsityPattern argument had quadratic complexity in the number of - rows for sparsity patterns where most of the rows are of length zero. The bad - algorithm has been replaced by a linear complexity one. -

    49. - -
  49. New: It is now possible to generate a cell_iterator to a cell - that is identified by a CellId. CellIds are unique even across - processes in distributed computations, therefore this change allows - to identify a particular cell (e.g. a ghost cell of the local process) in - another domain. -

    61. - -
  61. Fixed: Level indices for geometric multigrid queried through - DoFAccessor::get_mg_dof_indices() would return wrong indices on lines - and faces in non-standard orientation in 3D. This is now fixed. -
    - (Martin Kronbichler, 2016/07/27) -
    62. - -
  62. New: There is now a new DoFTools::make_flux_sparsity_pattern() - which takes a constraint matrix and flux and internal dof masks, in - parallel. This is useful in the case where some components of a - finite element are continuous and some discontinuous, allowing - constraints to be imposed on the continuous part while also building - building the flux terms needed for the discontinuous part. -
    - (Sam Cox, 2016/07/25) -

    71. - -
  71. Fixed: FEValues::reinit() would sometimes try to be overly - clever and not re-compute information when called with the same - cell twice in a row, even if the underlying triangulation had - been moved, translated, stretched, or otherwise had its vertex - locations changed between the two calls to FEValues::reinit(). - This is now fixed. -

    - (Michael Harmon, 2016/06/30) -
    79. - -
  79. Changed: Similar to MappingQEulerian, MappingQ1Eulerian has gained - a second constructor that reverses the order of the arguments to indicate - which DoFHandler a vector is based on. The old constructor is now - deprecated and will be removed in a future version. -
    - (Wolfgang Bangerth, 2016/06/25) -
    80. - -
  80. New: The MappingFEField class was previously only instantiated - if the vector type was dealii::Vector. It is now also instantiated - for PETSc and Trilinos wrapper vector types. -

    85. - -
  85. Fixed: FEFieldFunction now works correctly in distributed computations, - where before exceptions of type ExcPointNotAvailableHere could occur for - evaluation points on or close to a boundary to a ghost cell. -
    - (Timo Heister, 2016/06/06) -
    86. - -
  86. Fixed: The Tensor class was not explicitly instantiated. This did - not matter in almost all contexts because its members are all defined - as @p inline in the header file. The only cases where it matters if one - (or the compiler) were to take the address of one of the static member - variables. -
    - (Wolfgang Bangerth, 2016/06/03) -
    87. - -
  87. New: Return value std::vector vertex_mapping for the - DoFTools::make_vertex_patches() function, including the optional inversion - of the vertex mapping. -

    94. - -
  94. Improved: The method Triangulation::create_triangulation will now throw an - exception if any cells have negative measure. This check is not run if the - triangulation keeps track of distorted cells or if the codimension is not zero. - This check was previously only run in 3D. -
    - (David Wells, 2016/05/07) -
    95. - -
  95. Fixed: Bug in the RelaxationBlock class function do_step. Before, the - corrections were not added together, which leads to a wrong update whenever the - Jacobi blocks are overlapping. For SOR, SSOR and non-overlapping Jacobi this was - not an issue. -
    - (Joscha Gedicke, 2016/05/07) -
    96. - -
  96. Fixed: The function GridGenerator::subdivided_parallelepiped and its - variants could generate meshes with cells that had negative Jacobians. - The function now detects when this will happen and raises a descriptive - exception instead of going on to produce cells which may have negative measure. -
    - (David Wells, 2016/05/11) -
    97. - -
  97. New: Added function GridOut::write_mesh_per_processor_as_vtu. This allows - the visualization of a parallel finite element mesh that can be separated into each - processor's owned and ghost cells. It also allows for the visualization of each level - of a multilevel mesh. -
    - (Conrad Clevenger, 2016/04/28) -
    98. - -
  98. Fixed: TrilinosWrappers::SparseMatrix will now exit early if there are no - entries to add to the matrix. This usually occurs when zero elision is on. This - fixes a bug where the matrix raises an exception if there are no entries to add - to a matrix and the provided row and column values are not locally stored. -
    - (David Wells, 2016/04/24) -
    99. - -
  99. Fixed: TrilinosWrappers::MPI::Vector and TrilinosWrappers::Vector could - access invalid memory in the reinit() method if the MPI communicator was - deleted before termination of the program. This usually happened when using - vectors from GrowingVectorMemory where a pool keeps vector alive. This has - been fixed. -
    - (Martin Kronbichler, 2016/04/23) -
    100. - -
  100. Fixed: The methods TrilinosWrappers::SparseMatrix::(T)mmult previously - produced invalid matrix sizes if the final matrix was non-square. This has - been fixed. -

    101. - -
  101. New: Added an optional string parameter to the ParameterHandler::read_input () - and ParameterHandler::read_input_from_string() functions. - When a line which equals this string is encountered, the parsing of parameters - is terminated. -

    104. - -
  104. Improved: The parallel loops in the deal.II Vector class for - vector-vector operations have been revised for performance.

    - (Martin Kronbichler, 2016/04/14) -
    105. - -
  105. New: added ReinitHelper for PETSc. This is required by LinearOperator - class to reinit vectors. -

    107. - -
  107. Fixed and improved: Fix algorithm for incomplete assignment of level - subdomain ids for parallel geometric multigrid. Also optimize algorithms - used for assignment and DoF communication. -
    - (Timo Heister, Martin Kronbichler, 2016/04/12) -
    108. - -
  108. New: Added New option in the read_ucd function of the GridIn class. - A flag can now be assigned to the function, to decide wether the - indicators specified in a UCD file should be interpreted as - boundary_ids or as manifold_ids. This is particularly useful - when the indicators refer to internal faces, for which - boundary_ids cannot be used. -
    - (Andrea Mola, 2016/04/11) -
    109. - -
  109. Improved: DoFRenumbering::compute_Cuthill_McKee when used with - distributed triangulations contained parts that scaled as the global problem - size, rather than the processor-local size. This prevented its use with more - than a few hundred cores when hanging node constraints were activated. This - has been fixed. -
    - (Martin Kronbichler, 2016/04/11) -
    110. - -
  110. New: added hessenberg_signal and krylov_space_signal to SolverGMRES. - These signals allow to retrieve the Hessenberg matrix and the basis vectors - generated by the Arnoldi algorithm. -

    114. - -
  114. Fixed: The multigrid transfer performed invalid data accesses on - multigrid hierarchies that define the coarse level as a level larger than - 0. This has been fixed. -
    - (Martin Kronbichler, 2016/04/03) -
    115. - -
  115. New: Add GridTools::remove_hanging_nodes() and - GridTools::remove_anisotropy() in GridTools. GridTools::remove_hanging_nodes() - detects cells with hanging nodes and refines the neighbours in the direction - that removes hanging nodes or in every directions. - GridTools::remove_anisotropy() refines a mesh until the resulting mesh is - composed by cells with ratio between the extension in each coordinate - direction lower than a fixed value. -
    - (Mauro Bardelloni, 2016/03/28) -
    116. - -
  116. New: When using C++11, a move constructor and assignment operator has - been added to SparseMatrix, so that these objects can be returned from - functions and packed into pairs and tuples. -

    117. - -
  117. New: The product of a rank-1 tensor (a vector) and a rank-2 - symmetric tensor (a symmetric matrix) is now defined and yields - a rank-1 tensor (a vector). The opposite product was previously - already defined. -

    - (Timo Heister, 2016/03/21) -
    120. - -
  120. Fixed: DoFHandler::locally_owned_dofs() could create a segmentation - fault in cases where some processors do not own any cells. This was caused - by an incorrect computation in DoFTools::locally_owned_dofs_per_subdomain(). -
    - (Wolfgang Bangerth, 2016/03/20) -
    121. - -
  121. Improved: The distribution of degrees of freedom on multigrid levels, - DoFHandler::distribute_mg_dofs(), contained a few steps that scaled - quadratically in the number of local cells for certain configurations. These - steps have been replaced by linear complexity calls. -
