mesh, create the parallel 'Nodes' using directly the
ParNURBSExtension created in the constructor, instead of
creating another extension by calling the ParGridFunction
constructor that is used in the general case.
ElementsTransformation inversion algorithms, and serves as a base class
for other, e.g. custom, implementations. The new class contains all
previous implementations of ElementTransformation::TransformBack() and
adds a some new options.
The method IsoparametricTransformation::TransformBack() is now
implemented by simply constructing a InverseElementTransformation object
(with default options) and calling its Transform() method.
Updated the methods Mesh::FindPoints() and ParMesh::FindPoints() to
accept an optional argument of type InverseElementTransformation,
allowing more flexibility through customization of the transformation
inversion algorithm. In ParMesh::FindPoints(), when the i-th point was
found by one or more ranks, the output entry elem_ids[i] will be set to
-2 (except on the rank that is assigned that point) to indicate that the
i-th point was found but assigned to another rank - this value allows
all ranks to distinguish this case from the case when a point was not
found by any rank - indicated by elem_ids[j] set to -1.
Added two new methods to class ElementTransformation: GetGeometryType()
and GetDimension(). To aviod making these new methods virtual (and to
make the existing method GetSpaceDim() non-virtual), added data fields
'geom' and 'space_dim' to the base class ElementTransformation. In order
to facilitate the initialization of those fields for class
IsoparametricTransformation, added new method, FinalizeTransformation().
This method must be called after setting the point-matrix and the finite
element of the IsoparametricTransformation - all such places in MFEM
have been updated to perform that call.
Add new version of Geometry::ProjectPoint() that projects points outside
the reference element to the closest boundary point of the element.
Updated class GeometryRefiner to allow simultaneous use by different
places in a code - new calls to the Refine() and RefineInterior()
methods will not destroy previously allocated and returned objects by
the same calls.
general/globals.[ch].
Renamed class WrappedOStream to OutStream and use a different
implementation in order to support the case when the OutStream is passed
as a parameter of type std::ostream.
In class MPI_Session, added an MPI_Comm parameter to both constructors,
with a default value of MPI_COMM_WORLD.
Hide the global variable MFEM_COMM_WORLD and allow access (read and
write) with global functions: GetGlobalMPI_Comm() and
SetGlobalMPI_Comm() - in the future, we may want to perform some tasks
when changing the "global" MPI communicator.
In mfem_error(), use GetGlobalMPI_Comm() instead of MPI_COMM_WORLD.
Minor formatting changes and #include reordering.
Adding a serial method to obtain the information printed by
PrintCharacteristics. This includes minimum and maximum edge lengths
as well as kappa which seems to be related to the aspect ratio of the
elements.
Adding a parallel method to compute the same mesh characteristics
mentioned above.
Adding a parallel method to compute the bounding box of a distributed
mesh.
