+<!-- ----------- 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> 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>
+</ol>
+
+
+<!-- ----------- GENERAL IMPROVEMENTS ----------------- -->
+
+<a name="general"></a>
+<h3>General</h3>
+
+<ol>
+<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 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> 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> 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: 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>
+
+ <li> Fixed: GridGenerator::hyper_cube_slit() with colorized set to
+ true is now working correctly.
+ <br>
+ (Timo Heister, 2016/10/04)
+ </li>
+
+ <li> Fixed: SphericalManifold now behaves correctly also when R>>1
+ and the center is not the origin.
+ <br>
+ (Luca Heltai, 2016/10/01)
+ </li>
+
+ <li> New: FETools::extrapolate allows for using the
+ extrapolate algorithm on parallel::distributed::Triangulations.
+ <br>
+ (Daniel Arndt, Martin Steigemann, 2016/09/28)
+ </li>
+
+ <li> Improved: Some parts of mesh refinement are now parallelized.
+ <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
+ support point locations and dof indices to a format readable by
+ gnuplot.
+ <br>
+ (Timo Heister, 2016/09/16)
+ </li>
+
+ <li> Fixed: EmbeddedRungeKutta methods now correctly increase delta_t_guess
+ when the error is below coarsen_tol.
+ <br>
+ (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).
+ <br>
+ (Martin Kronbichler, 2016/09/16)
+ </li>
+
+ <li> New: LinearAlgebra::Vector is now instantiated for float and double.
+ <br>
+ (Bruno Turcksin, 2016/09/15)
+ </li>
+
+ <li> New: The class MGCoarseGridIterativeSolver is replacing
+ 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.
+ <br>
+ (Wolfgang Bangerth, 2016/08/11)
+ </li>
+
+ <li> New: Implement MGCoarseGridApplySmoother class to do a few steps of a
+ smoother at the coarsest level.
+ <br>
+ (Denis Davydov, 2016/08/09)
+ </li>
+
+ <li> New: PreconditionMG can now be used as a LinearOperator.
+ <br>
+ (Denis Davydov, 2016/08/09)
+ </li>
+
+ <li> New: RelaxationBlock classes for geometric multigrid now support parallel
+ computations using Trilinos.
+ <br>
+ (Timo Heister, Guido Kanschat, 2016/08/08)
+ </li>
+
+ <li>
+ New: Added a new PolarManifold descriptor, that uses a polar coordinate
+ system to compute new points, and modified the existing SphericalManifold
+ 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> Improved: DoFTools::make_cell_patches() can create block lists
+ only extending over local cells of distributed triangulations.
+ <br>
+ (Guido Kanschat, 2016/08/02)
+ </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.
+ <br>
+ (Jonathan Robey, 2016/07/21)
+ </li>
+
+ <li> Improved: Allow for including dofs for individual components on
+ boundary in DoFTools::make_vertex_patches().
+ <br>
+ (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
+ intersection of a hyper ball with the positive orthant relative
+ 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>
+
+ <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
+ finite elements out of simpler finite elements, either by forming tensor
+ 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
+ errors from cellwise errors obtained by VectorTools::integrate_difference()
+ 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.
+ <br>
+ (Timo Heister, 2016/03/21)
+ </li>
+
+ <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>
+ (Spencer Patty, 2016/02/11)
