-<!-- ----------- INCOMPATIBILITIES ----------------- -->
-
-<a name="incompatible"></a>
-<h3 style="color:red">Incompatibilities</h3>
-
-<p style="color:red">
-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.
-</p>
-
-<ol>
- <li> 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.
- <br>
- (Wolfgang Bangerth, 2016/12/03)
- </li>
-
- <li> Changed: VectorTools::create_right_hand_side and
- VectorTools::create_boundary_right_hand_side now take an additional template
- parameter VectorType.
- <br>
- (Daniel Arndt, 2016/10/25)
- </li>
-
- <li> 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.
- <br>
- (David Wells, 2016/09/15)
- </li>
-
- <li> Deprecated: MGCoarseGridLACIteration got deprecated in favor of
- MGCoarseGridIterativeSolver.
- <br>
- (Timo Heister, 2016/09/14)
- </li>
-
- <li> 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).
- <br>
- (David Wells, 2016/09/06)
- </li>
-
- <li> 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.
- <br>
- (Wolfgang Bangerth, 2016/08/22)
- </li>
-
- <li> Removed: Deprecated classes CompressedSparsityPattern,
- CompressedSimpleSparsityPattern, CompressedSetSparsityPattern, and their
- block variants got removed.
- <br>
- (Timo Heister, 2016/08/13)
- </li>
-
- <li> Deprecated: MGLevelObject::clear() deprecated in favor of
- MGLevelObject::clear_elements() due to clear() being inconsistent with
- behavior of other container objects.
- <br>
- (Jonathan Robey, 2016/08/08)
- </li>
-
- <li> Changed: Several operators from LocalIntegrators::Divergence got moved
- to LocalIntegrators::GradDiv and the never used/tested
- LocalIntegrators::Divergence::grad_div() function was removed.
- <br>
- (Timo Heister, Guido Kanschat, 2016/08/02)
- </li>
-
- <li> 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.
- <br>
- At the same time, we changed the dof handler template to the type DoFHandler,
- since hp::DoFHandler requires a different setup of the SparsityPattern.
- <br>
- (Guido Kanschat, 2016/08/02)
- </li>
-
- <li> 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 <code>explicit</code>, 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.
- <br>
- (Wolfgang Bangerth, 2016/06/25)
- </li>
-
- <li> 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 <tt>operator==</tt>, <tt>operator!=</tt>, and
- <tt>is_non_negative</tt> have been removed from the new interface.
- <br>
- (Martin Kronbichler, 2016/06/15)
- </li>
-
- <li> Changed: The Triangulation::Signals::clear signal is now triggered
- <i>before</i>, not <i>after</i> the internal data structures of the
- triangulation are destroyed. This allows functions attached to the signal to
- save information associated with the triangulation.
- <br>
- (Wolfgang Bangerth, 2016/06/07)
- </li>
-
- <li> Changed: deal.II used to create template instantiations for scalar
- types <tt>double</tt>, <tt>float</tt>, and <tt>long double</tt>. Since
- <tt>long double</tt> 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 <tt>double</tt> 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 <tt>long double</tt> data
- structures and get linker errors stating undefined symbols involving
- <tt>long double</tt>, include the respective <tt>.templates.h</tt> file(s)
- with the code definitions. See the section on @ref Instantiations in the
- manual for further information.
- <br>
- (Martin Kronbichler, 2016/04/26)
- </li>
-
- <li> Changed: FlatManifold takes as argument a periodicity option. This
- used to be a Point<dim>, but it should have been a Tensor<1,dim>. This
- is now changed.
- <br>
- (Luca Heltai, 2016/04/09)
- </li>
-
- <li> 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
- <tt>FE_Q<dim>(QIterated<1>(QTrapez<1>(),degree))</tt> or
- <tt>FE_DGQArbitraryNodes<dim>(QIterated<1>(QTrapez<1>(),degree))</tt>.
- <br>
- (Martin Kronbichler, 2016/04/05)
- </li>
-
- <li> Removed: Support for the legacy <code>Make.global_options</code>
- file has been removed.
- <br>
- (Matthias Maier, 2016/03/17)
- </li>
-
- <li> Removed: Functions with names containing <code>boundary_indicator</code>
- have been removed. They had previously already been deprecated, and replaced
- by functions containing the string <code>boundary_id</code> instead, to keep
- with the style used for <code>material_id</code>, <code>subdomain_id</code>,
- etc.
- <br>
- (Wolfgang Bangerth, 2016/02/28)
- </li>
-
- <li> Changed: Many functions in VectorTools and MatrixTools now require
- matching data types between vectors, matrices, and Function arguments.
- <br>
- (Denis Davydov, 2016/02/27)
- </li>
-
- <li> 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.
- <br>
- (Denis Davydov, 2016/02/22)
- </li>

-
-
-<!-- ----------- GENERAL IMPROVEMENTS ----------------- -->
-
-<a name="general"></a>
-<h3>General</h3>
-
-<ol>
-
- <li> 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.
- <br>
- (Jean-Paul Pelteret, Andrew McBride, 2016/12/05)
- </li>
-
- <li> 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.
- <br>
- (Jean-Paul Pelteret, Andrew McBride, 2016/12/05)
- </li>
-
- <li> 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.
- <br>
- (Jean-Paul Pelteret, 2016/12/05)
- </li>
-
-<li> 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.
- <br>
- (Martin Kronbichler, 2016/11/23)
-</li>
-
-<li> 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.
- <br>
- (David Wells, 2016/11/09)
-</li>
-
- <li>
- 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.
- <br>
- (Konstantin Ladutenko and many others, 2016/11/08)
- </li>
-
- <li> Improved: The way DataPostprocessor receives its input has been updated.
- <br>
- 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.
- <br>
- 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.
- <br>
- (Wolfgang Bangerth, 2016/10/31)
- </li>
-
- <li> 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.
- <br>
- (Wolfgang Bangerth, 2016/10/28)
- </li>
-
- <li> Improved: deal.II now bundles a subset of BOOST 1.62 instead of a subset
- of BOOST 1.56.
- <br>
- (David Wells, 2016/10/20)
- </li>
-
- <li> 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.
- <br>
- (Jaeryun Yim, 2016/10/01)
- </li>
-
- <li> 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.
- <br>
- (Denis Davydov, 2016/09/28)
- </li>
-
- <li> New: The Tensor class has two new functions implemented, namely those
- that return its Tensor::adjoint() and Tensor::cofactor().
- <br>
- (Jean-Paul Pelteret, 2016/09/25)
- </li>
-
- <li> Improved: The doxygen documentation now contains nicely formatted
- boxes containing the text message of each exception. Several messages
- haven been clarified and improved.
- <br>
- (Timo Heister, 2016/09/06)
- </li>
-
- <li> 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})
- <br>
- (Wolfgang Bangerth, 2016/08/19)
- </li>
-
- <li> 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.
- <br>
- (David Wells, Jonathan Robey, Wolfgang Bangerth, 2016/08/11)
- </li>
-
- <li>
- 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.
- <br>
- (Bruno Turcksin, 2016/08/03)
- </li>
-
- <li>
- Improved: A few of the introductory examples (steps five through eight) no
- longer use the Function class; they use plain functions instead.
- <br>
- (David Wells, 2016/07/25)
- </li>
-
- <li> 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.
- <br>
- (Matthias Maier, 2016/07/13)
- </li>
-
- <li> Improved: The testsuite now supports fine grained feature constraints
- of the form <code>test.with_[feature]_with_[...]=true</code> corresponding
- to variables <code>DEAL_II_<FEATURE>_WITH_[...]</code> exported to
- <code>deal.IIConfig.cmake</code>.
- <br>
- (Matthias Maier, 2016/07/11)
- </li>
-
- <li> New: The library is now compatible with PETSc 3.7.0. Part of this change
- included adding a new header, <tt>petsc_compatibility.h</tt>, which provides
- some version-independent functions for using common PETSc functions.
- <br>
- (David Wells, 2016/07/07)
- </li>
-
- <li> 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
- <br>
- (Matthias Maier, Timo Heister, 2016/07/06)
- </li>
-
- <li> 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.
- <br>
- (Denis Davydov, 2016/06/23)
- </li>
-
- <li> New: The tutorial step-55 shows how to solve the Stokes system
- in parallel with PETSc or Trilinos.
- <br>
- (Timo Heister, 2016/06/17)
- </li>
-
- <li> New: The tutorial step-56 demonstrates Geometric Multigrid for the
- Stokes equations.
- <br>
- (Ryan Grove, Timo Heister, 2016/06/01)
- </li>
-
- <li> 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.
- <br>
- (Jean-Paul Pelteret, 2016/05/20)
- </li>
-
- <li> 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.
- <br>
- (Denis Davydov, Jean-Paul Pelteret, 2016/04/30)
- </li>
-
- <li> New: Added an interface to the GNU Scientific Library. Also introduce a
- cubic spline interpolation function Functions::CSpline.
- <br>
- (Denis Davydov, 2016/04/28)
- </li>
-
- <li> New: Added move operations to BlockIndices, BlockVectorBase and
- BlockVector; Vector move operations nullify old object instead of
- using swap.
- <br>
- (Daniel Shapero, 2016/04/13)
- </li>
-
- <li> 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.
- <br>
- 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.
- <br>
- (Luca Heltai, Wolfgang Bangerth, 2016/04/08)
- </li>
-
- <li> 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.
- <br>
- (Luca Heltai, 2016/04/09)
- </li>
-
- <li> New: Added indent target to indent all headers and source
- files. Now you can do make (or ninja) indent inside the build
- directory.
- <br>
- (Alberto Sartori, 2016/03/02)
- </li>
-</ol>
-
-
-<!-- ----------- SPECIFIC IMPROVEMENTS ----------------- -->
-
-<a name="specific"></a>
-<h3>Specific improvements</h3>
-
-<ol>
- <li> New: The ArrayView class now has a default constructor that creates
- an invalid object.
- <br>
- (Wolfgang Bangerth, 2016/12/08)
- </li>
-
- <li> Fixed: ArrayView objects to empty views could not be copied.
- This is now fixed.
- <br>
- (Wolfgang Bangerth, 2016/12/07)
- </li>
-
-<li> 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.
- <br>
- (David Wells, 2016/12/07)
-</li>
-
-<li> 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.
- <br>
- (Jean-Paul Pelteret, 2016/12/07)
-</li>
-
-<li> 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.
- <br>
- (Wolfgang Bangerth, 2016/12/03)
- </li>
-
- <li> 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.
- <br>
- (Daniel Arndt, 2016/11/25)
- </li>
-
- <li> 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.
- <br>
- (Wolfgang Bangerth, 2016/11/15)
- </li>
-
- <li> Fixed: Calling MappingQ::clone() did not copy the
- <code>use_mapping_q_on_all_cells</code> 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.
- <br>
- (Sebastian Gonzalez-Pintor, Wolfgang Bangerth, 2016/11/15)
- </li>
-
- <li> Fixed: Objects of type TrilinosWrappers::SparsityPattern::const_iterator
- were entirely unusable due to a bug. This is now fixed.
- <br>
- (Wolfgang Bangerth, 2016/11/15)
- </li>
-
- <li> 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.
- <br>
- (Wolfgang Bangerth, 2016/11/10)
- </li>
-
- <li> New: Add PArpackSolver::reinit(const VectorType &distributed_vector) to
- initialize internal data structures based on a vector. This makes PArpack
- usable with MatrixFree operators.
- <br>
- (Denis Davydov, 2016/10/31)
- </li>
-
- <li> New: VectorTools::project can be used for parallel Triangulations in
- specific cases.
- <br>
- (Daniel Arndt, 2016/10/30)
- </li>
-
- <li> New: Add MatrixFreeOperators::LaplaceOperator representing a Laplace matrix.
- <br>
- (Denis Davydov, 2016/10/30)
- </li>
-
- <li> New: Add VectorTools::project() to do L2 projection
- of scalar-valued quadrature point data in parallel.
- <br>
- (Denis Davydov, 2016/10/28)
- </li>
-
- <li> Fixed: Increased precision of timesteps in DataOutInterface::write_pvd_record().
- <br>
- (Rajat Arora, 2016/10/29)
- </li>
-
- <li> New: Add MatrixFreeOperators::MassOperator representing a mass matrix.
- <br>
- (Daniel Arndt, 2016/10/27)
- </li>
-
- <li> 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.
- <br>
- (Martin Kronbichler, 2016/10/27)
- </li>
-
- <li> 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.
- <br>
- (Martin Kronbichler, 2016/10/27)
- </li>
-
- <li> >New: VectorTools::create_right_hand_side can be used for parallel
- Triangulations and homogeneous constraints using a ConstraintMatrix.
- <br>
- (Daniel Arndt, 2016/10/25)
- </li>
-
- <li> 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.
- <br>
- (Mayank Sabharwal, Wolfgang Bangerth, 2016/10/25)
- </li>
-
- <li> New: Add ArpackSolver::set_shift() to set the shift value in spectral
- transformation.
- <br>
- (Denis Davydov, 2016/10/25)
- </li>
-
- <li> New: PreconditionChebyshev now offers a PreconditionChebyshev::step()
- and PreconditionChebyshev::Tstep() methods for usage in relaxation smoothers.
- <br>
- (Martin Kronbichler, 2016/10/21)
- </li>
-
- <li> 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.
- <br>
- (Wolfgang Bangerth, 2016/10/20)
- </li>
-
- <li> New: Add a base class for matrix-free operators MatrixFreeOperators::Base.
- <br>
- (Denis Davydov, 2016/10/16)
- </li>
-
- <li> 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.
- <br>
- (Martin Kronbichler, 2016/10/14)
- </li>
-

- <br>
- (Wolfgang Bangerth, 2016/09/27)
- </li>
-
- <li> Improved: MGSmootherBlock is now able to use the shared memory pool for
- temporary vector allocation. The constructor requiring an external memory
- allocation has therefore been deprecated.
- <br>
- (Jonathan Robey, 2016/09/21)
- </li>
-
- <li> New: DoFTools::write_gnuplot_dof_support_point_info outputs

- gnuplot.
- <br>
- (Timo Heister, 2016/09/16)

-
- <li> Fixed: EmbeddedRungeKutta methods now correctly increase delta_t_guess

- (Vaibhav Palkar, Bruno Turcksin, 2016/09/16)
- </li>
-
- <li> Fixed: TrilinosWrappers::MPI::Vector::locally_owned_elements()
- now returns the correct IndexSet also if initialized with two
- IndexSets.
- <br>
- (Daniel Arndt, 2016/09/16)
- </li>
-
- <li> 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.
- <br>
- (Martin Kronbichler, 2016/09/16)
- </li>
-
- <li> Fixed: The Multigrid W-cycle and F-cycle have been fixed (for uniform
- grids).

- (Martin Kronbichler, 2016/09/16)
- </li>
-
- <li> New: LinearAlgebra::Vector is now instantiated for float and double.

- MGCoarseGridLACIteration with a simpler interface.
- <br>
- (Timo Heister, 2016/09/14)
- </li>
-
- <li> Improved: FEValues no longer generates the mapping's internal database if
- the mapping will not be required for the set of update flags specified.
- <br>
- (Jonathan Robey, 2016/09/14)
- </li>
-
- <li> Fixed: Instantiating class Vector with non-standard template
- arguments did not work because of duplicate function symbols. This
- is now fixed.
- <br>
- (Dragan Nikolic, 2016/09/14)
- </li>
-
- <li> Fixed: IndexSet::make_trilinos_map now treats non-ascending but
- contiguous IndexSets correctly. It creates a linear EpetraMap only
- if the IndexSets are ascending and 1:1.
- <br>
- (Daniel Arndt, 2016/09/11)
- </li>
-
- <li> New: IndexSet::is_ascending_and_one_to_one allows to find out
- whether the nth range of indices is stored on the nth process in case
- the IndexSets are contiguous.
- <br>
- (Daniel Arndt, 2016/09/11)
- </li>
-
- <li> Fixed: The CMake macros <code>DEAL_II_(ADD_TEST|SETUP_TARGET)</code>
- now enforce a stricter <code>CMAKE_BUILD_TYPE</code> handling. This helps
- to avoid situations where targets with different build flavors might
- accidentally get linked against each other.
- <br>
- (Matthias Maier, 2016/09/08)
- </li>
-
- <li> Fixed: FE_TraceQ now provides unit support points.
- <br>
- (Martin Kronbichler, 2016/09/08)
- </li>
-
- <li> Fixed: Reimplement copy_triangulation and load in
- dealii::parallel::shared::Triangulation, this avoids the loss of
- partition information which causes parallel::shared::Triangulation to be in an invalid state.
- <br>
- (Ce Qin, 2016/09/05)
- </li>
-
- <li> Fixed: The build system now uses -fPIC instead of -fpic
- <br>
- (Matthias Maier, 2016/08/31)
- </li>
-
- <li> Fixed: Fix MPI_InitFinalize by correctly initializing and destroying
- all p4est/libsc related objects by calls to sc_init(), p4est_init(), and
- sc_finalize(); compatibility with p4est versions >1.1.
- <br>
- (Jonathan Perry-Houts, 2016/08/31)
- </li>
-
- <li> 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.
- <br>
- (Dustin Kumor, Martin Kronbichler, 2016/08/31)
- </li>
-
- <li> New: There is now the possibility to store information about the
- time of an output time step within the .visit file created by
- the DataOutInterface<dim,spacedim>::write_visit_record function.
- <br>
- (Rene Gassmoeller, Juliane Dannberg, 2016/08/24)
- </li>
-
- <li> 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.
- <br>
- (Rene Gassmoeller, 2016/08/17)
- </li>
-
- <li> New: Rank-4 symmetric tensors of type SymmetricTensor can now
- be converted to rank-4 tensors of type Tensor.

- </li>
-
- <li>
- New: Added a new PolarManifold descriptor, that uses a polar coordinate

- descriptor to use geodesics on the surface of the sphere.
- <br>
- (Luca Heltai, Mauro Bardelloni, 2016/08/04)
- </li>
-
- <li> Improved: The regular and hp versions of
- DoFTools::make_flux_sparsity_pattern() no longer use the user flags of the
- underlying triangulation to determine if entries along a certain face have been
- added to the sparsity pattern.
- <br>
- (David Wells, 2016/03/02 - 2016/08/02)
- </li>
-
- <li> New: Introduce operators for residuals and interior penalty terms for
- the Grad-Div operator in LocalIntegrators::GradDiv.
- <br>
- (Timo Heister, Guido Kanschat, 2016/08/02)
- </li>

- </li>
-
- <li> Fixed: (P)ARPACK interface for non-symmetric matrices.
- <br>
- (Joscha Gedicke, 2016/08/01)
- </li>
-
- <li> Fixed: The TrilinosWrappers::SparsityPattern::print() and
- TrilinosWrappers::SparsityPattern::print_gnuplot() methods did not produce
- correct output on distributed computations. This is now fixed.
- <br>
- (Martin Kronbichler, 2016/07/30)
- </li>
-
- <li> Fixed: CMake now tries to pick up the full link interface for gsl.
- This works around an underlinkage issue with libgsl.so not correctly
- stating all shared object dependencies.
- <br>
- (Matthias Maier, 2016/07/28)
- </li>
-
- <li> 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.
- <br>
- (Martin Kronbichler, 2016/07/27)
- </li>
-
- <li> 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.
- <br>
- (Sam Cox, 2016/07/25)
- </li>
-
- <li>
- Improved: VectorTools::interpolate() may now be used on FESystems with mixed
- interpolating and non-interpolating FEs, if all of the selected components for
- interpolation originate from interpolating FEs.
- <br>
- (Jonathan Robey, 2016/07/24)
- </li>
-
- <li>
- Improved: VectorTools::interpolate() now takes a ComponentMask to select the
- components to interpolate.
- <br>
- (Jonathan Robey, 2016/07/21)
- </li>
-
- <li> Improved: Split out pattern descriptions for LaTeX and Description
- ParameterHandler OutputStyles, and add better description text.

- (Ryan Grove, Daniel Arndt, 2016/07/21)
- </li>
-
- <li> Improved: Allow for initializing the constrained
- boundary DoFs in MGConstrainedDoFs using a std::set
- instead of a FunctionMap whose function values were not used.
- Allow for non-primitive FiniteElements.
- <br>
- (Daniel Arndt, 2016/07/20)
- </li>
-
- <li> New: Added GridGenerator::quarter_hyper_ball() to generate the

- to its center.
- <br>
- (Daniel Arndt, 2016/07/19)
- </li>
-
- <li> Fixed: Work around an issue with the OpenMPI installation on certain
- Ubuntu versions: The build system now automatically drops the
- "-fuse-ld=gold" linker flag if openmpi is incompatible with it.
- <br>
- (Wolfgang Bangerth, Martin Kronbichler, Matthias Maier, 2016/07/13)
- </li>
-
- <li> Fixed: CMake now handles mixed compiler and linker setup via
- <code>DEAL_II_CXX_FLAGS*</code> / <code>DEAL_II_LINKER_FLAGS*</code> and
- <code>CMAKE_CXX_FLAGS*</code> properly.
- <br>
- (Matthias Maier, 2016/07/13)
- </li>
-
- <li> 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.
- <br>
- (Wolfgang Bangerth, Jean-Paul Pelteret, Rajat Arora, 2016/07/11)
- </li>
-
- <li> Fixed: Allow to use FETools::get_fe_by_name for all
- availabale FiniteElements.
- <br>
- (Daniel Arndt, 2016/07/10)
- </li>
-
- <li> Fixed: SymmetricTensor::access_raw_entry() erroneously produced
- an indexing error for rank-4 symmetric tensors. This is now fixed.
- <br>
- (Wolfgang Bangerth, 2016/07/08)
- </li>
-
- <li> Fixed: SymmetricTensor::norm() did not work correctly for complex
- underlying scalar types. This is now fixed.
- <br>
- (Wolfgang Bangerth, 2016/07/08)
- </li>
-
- <li> New: There is now a function DerivativeForm::norm().
- <br>
- (Wolfgang Bangerth, 2016/07/08)

-
- <li> New: A move constructor has been added to Triangulation.
- <br>
- (Daniel Shapero, 2016/07/07)
- </li>
-
- <li> Fixed: The function DoFTools::dof_couplings_from_component_couplings
- for hp::FECollection arguments was compiled but not exported from the
- object file. This is now fixed.
- <br>
- (Wolfgang Bangerth, 2016/07/01)
- </li>
-
- <li> New: Added TrilinosWrappers::SolveDirect::initialize and
- TrilinosWrappers::SolverDirect::solve to solve distributed linear systems
- with multiple right hand sides without needing to refactorize the matrix
- everytime.
- <br>
- (Michael Harmon, 2016/06/30)
- </li>
-
- <li> 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.
- <br>
- (Wolfgang Bangerth, 2016/06/25)
- </li>
-
- <li> 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.
- <br>
- (Wolfgang Bangerth, 2016/06/25)
- </li>
-
- <li> New: GnuplotFlags now supports user specified space dimension labels
- through a member variable.
- <br>
- (David Wells, 2016/06/24)
- </li>
-
- <li> New: Added an operator* to SynchronousIterators which returns a
- reference to the stored tuple of iterators iterators. The iterators member
- may be made private in a future release.
- <br>
- (Daniel Shapero, 2016/06/24)
- </li>
-
- <li> New: IndexSet::at(idx) returns an iterator pointing to the given index
- or the next larger element in the set if idx is not contained.
- <br>
- (Timo Heister, 2016/06/21)
- </li>
-
- <li> Fixed: Performance of DynamicSparsityPattern::begin(r) and
- DynamicSparsityPattern::end(r) has been improved dramatically in parallel
- computations and if the pattern is empty.
- <br>
- (Timo Heister, 2016/06/21)
- </li>
-
- <li> 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.
- <br>
- (Timo Heister, 2016/06/06)
- </li>
-
- <li> 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.
- <br>
- (Wolfgang Bangerth, 2016/06/03)
- </li>
-
- <li> New: Return value std::vector<unsigned int> vertex_mapping for the
- DoFTools::make_vertex_patches() function, including the optional inversion
- of the vertex mapping.
- <br>
- (Joscha Gedicke, 2016/05/25)
- </li>
-
- <li> Fixed: Fix a bug where the SparsityPattern could not have more than 4
- billions entries when using 32bit indices.
- <br>
- (Bruno Turcksin, 2016/05/22)
- </li>
-
- <li> New: There are now additional functions in the FETools::Compositing namespace that build

- products or by combining the set of shape functions.
- <br>
- (Denis Davydov, Wolfgang Bangerth, 2016/05/20)
- </li>
-
- <li> New: Added PArpackSolver::reinit() when dealing with BlockVectors.
- <br>
- (Alberto Sartori, 2016/05/19)
- </li>
-
- <li> New: Add VectorTools::compute_global_error that computes global

- and do MPI collectives if necessary.
- <br>
- (Timo Heister, 2016/05/15)
- </li>
-
- <li> New: Add functions to transform Cartesian coordinates to spherical and back:
- GeometricUtilities::Coordinates::to_spherical and
- GeometricUtilities::Coordinates::from_spherical.
- <br>
- (Denis Davydov, 2016/05/10)
- </li>
-
- <li> Fixed: Corrected the sign of curl calculated in the functions:
- LocalIntegrators::curl_curl_matrix, LocalIntegrators::curl_matrix,
- LocalIntegrators::nitsche_curl_matrix and LocalIntegrators::ip_curl_matrix in
- integrators/maxwell.h.
- <br>
- (Jihuan Tian, 2016/05/09)
- </li>
-
- <li> 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.
- <br>
- (David Wells, 2016/05/07)
- </li>
-
- <li> 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.
- <br>
- (Joscha Gedicke, 2016/05/07)
- </li>
-
- <li> 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.
- <br>
- (David Wells, 2016/05/11)
- </li>
-
- <li> 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.
- <br>
- (Conrad Clevenger, 2016/04/28)
- </li>
-
- <li> 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.
- <br>
- (David Wells, 2016/04/24)
- </li>
-
- <li> 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.
- <br>
- (Martin Kronbichler, 2016/04/23)
- </li>
-
- <li> Fixed: The methods TrilinosWrappers::SparseMatrix::(T)mmult previously
- produced invalid matrix sizes if the final matrix was non-square. This has
- been fixed.
- <br>
- (Martin Kronbichler, Daniel Jodlbauer, 2016/04/21)
- </li>
-
- <li> 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.
- <br>
- (Denis Davydov, 2016/04/20)
- </li>
-
- <li> New: Added move operations to IndexSet.
- <br>
- (Daniel Shapero, 2016/04/19)
- </li>
-
- <li> Improved: MeshWorker treats periodic faces as interior faces.
- <br>
- (Daniel Arndt, 2016/04/18)
- </li>
-
- <li> Improved: The parallel loops in the deal.II Vector class for
- vector-vector operations have been revised for performance. This includes
- adjusting the minimum parallel grain size to 4096 vector entries and using an
- affinity partitioner provided by Threading Building Blocks for better data
- locality, especially on multi-socket systems.
- <br>
- (Martin Kronbichler, 2016/04/14)
- </li>
-
- <li> New: added ReinitHelper for PETSc. This is required by LinearOperator
- class to reinit vectors.
- <br>
- (Mauro Bardelloni, 2016/04/13)
- </li>
-
- <li> New: Added TensorProductManifold to create new manifolds from two
- ChartManifold objects. This can be used, for example, to combine a
- 2d manifold with a flat manifold for an extruded mesh.
- <br>
- (Timo Heister, 2016/04/12)
- </li>
-
- <li> 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.
- <br>
- (Timo Heister, Martin Kronbichler, 2016/04/12)
- </li>
-
- <li> 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.
- <br>
- (Andrea Mola, 2016/04/11)
- </li>
-
- <li> 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.
- <br>
- (Martin Kronbichler, 2016/04/11)
- </li>
-
- <li> 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.
- <br>
- (Giuseppe Pitton, Luca Heltai, 2016/04/11)
- </li>
-
- <li> New: Added CompositionManifold to create new manifolds from two
- ChartManifold objects. This can be used, for example, to rotate a
- cylindrical Manifold, or to make a cylinders with parabolic sides.
- <br>
- (Luca Heltai, 2016/04/09)
- </li>
-
- <li> Fixed: Meshworker::Assembler::ResidualSimple now also works for
- multiple blocks if no constraints are given.
- <br>
- (Daniel Arndt, 2016/04/08)
- </li>
-
- <li> New: A move constructor has been added to Quadrature.
- <br>
- (Daniel Shapero, 2016/04/08)
- </li>
-
- <li> 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.
- <br>
- (Martin Kronbichler, 2016/04/03)
- </li>
-
- <li> 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.
- <br>
- (Mauro Bardelloni, 2016/03/28)
- </li>
-
- <li> 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.
- <br>
- (Daniel Shapero, 2016/03/27)
- </li>
-
- <li> 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.
- <br>
- (Wolfgang Bangerth, 2016/03/25)
- </li>
-
- <li> New: Triangulation::add_periodicity allows for accessing neighbors across
- periodic boundaries via new functions in TriaAccessor.
- <br>
- (Daniel Arndt, Ali Samii, 2016/03/23)
- </li>
-
- <li> New: Added GridGenerator::torus() to generate the volume mesh of a
- torus in three dimensions and a manifold description TorusManifold to
- go with it.

-
- <li> 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().
- <br>
- (Wolfgang Bangerth, 2016/03/20)
- </li>
-
- <li> 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.
- <br>
- (Martin Kronbichler, 2016/03/18)
- </li>
-
- <li> New: Added GridTools::rotate() in three space dimensions.
- <br>
- (Timo Heister, 2016/03/18)
- </li>
-
- <li> New: Added custom target "relocate" to Mac OS X builds, that runs
- a script to make all paths absolute in the shared libraries included
- in the deal.II package (only enabled when building a package, and when
- including external libraries to the package)
- <br>
- (Luca Heltai, 2016/03/14)
- </li>
-
- <li> New: Added unit tests for complex-valued PETSc and SLEPc.
- <br>
- (Toby D. Young, Denis Davydov, 2016/03/11)
- </li>
-
- <li> New: Add NURBSPatchManifold. This class is a child of ChartManifold and
- implements a manifold descriptor for the face of a CAD imported usign
- OpenCASCADE.
- <br>
- (Mauro Bardelloni, 2016/03/09)
- </li>
-
- <li> New: When using C++11, there is now a function Threads::new_task()
- that can take as an argument either a lambda function, or the result
- of a std::bind expression, or anything else that can be called as in a
- function call. There is also a similar function Threads::new_thread()
- that takes the same kind of argument.
- <br>
- (Wolfgang Bangerth, 2016/03/07)
- </li>
-
- <li> New: Added another scaling factor to Kelly error estimator, namely h_K.
- <br>
- (Denis Davydov, 2016/03/05)
- </li>
-
- <li> New: When using C++11, the function filter_iterators() allows to filter a
- range of iterators using predicates (like the ones defined in IteratorFilter).
- <br>
- (Bruno Turcksin, 2016/03/04)
- </li>
-
- <li> Fixed: The OpenCASCADE::push_forward_and_differential_forms()
- function is now able to change the direction of the normal vector
- according to Orientation() method.
- <br>
- (Mauro Bardelloni, 2016/03/02)
- </li>
-
- <li> Fixed: The function IndexSet::make_trilinos_map() now works if some
- processors have a contiguous range of indices and others do not.
- <br>
- (Bruno Turcksin, 2016/02/17)
- </li>
-
- <li> Updated: step-44 has been been expressed in a more dimension independent
- manner, and can be now run in both 2-d and 3-d.
- <br>
- (Jean-Paul Pelteret, 2016/02/17)
- </li>
-
- <li> Fixed: FE_Nedelec elements up to polynomial order 12 can now be
- constructed.
- <br>
- (Jean-Paul Pelteret, 2016/02/12)
- </li>
-
- <li> Fixed: The GridTools::build_triangulation_from_patches() function now
- also copies the locations of vertices from the cells of the source
- triangulation to the triangulation that is built from the list of patch cells.
- <br>
