Detailed Description

Abstract parallel finite element space.

Definition at line 28 of file pfespace.hpp.

Constructor & Destructor Documentation

mfem::ParFiniteElementSpace::ParFiniteElementSpace	(	const ParFiniteElementSpace &	orig,
		ParMesh *	pmesh = `NULL`,
		const FiniteElementCollection *	fec = `NULL`
	)

Copy constructor: deep copy all data from orig except the ParMesh, the FiniteElementCollection, and some derived data.

If the pmesh or fec pointers are NULL (default), then the new ParFiniteElementSpace will reuse the respective pointers from orig. If any of these pointers is not NULL, the given pointer will be used instead of the one used by orig.

Note: The objects pointed to by the pmesh and fec parameters must be either the same objects as the ones used by orig, or copies of them. Otherwise, the behavior is undefined.; Derived data objects, such as the parallel prolongation and restriction operators, the update operator, and any of the face-neighbor data, will not be copied, even if they are created in the orig object.

Definition at line 30 of file pfespace.cpp.

mfem::ParFiniteElementSpace::ParFiniteElementSpace	(	const FiniteElementSpace &	orig,
		ParMesh &	pmesh,
		const FiniteElementCollection *	fec = `NULL`
	)

Convert/copy the local (Par)FiniteElementSpace orig to ParFiniteElementSpace: deep copy all data from orig except the Mesh, the FiniteElementCollection, and some derived data.

Definition at line 38 of file pfespace.cpp.

mfem::ParFiniteElementSpace::ParFiniteElementSpace	(	ParMesh *	pm,
		const FiniteElementSpace *	global_fes,
		const int *	partitioning,
		const FiniteElementCollection *	f = `NULL`
	)

Construct the local ParFiniteElementSpace corresponding to the global FE space, global_fes.

The parameter pm is the local ParMesh obtained by decomposing the global Mesh used by global_fes. The array partitioning represents the parallel decomposition - it maps global element ids to MPI ranks. If the FiniteElementCollection, f, is NULL (default), the FE collection used by global_fes will be reused. If f is not NULL, it must be the same as, or a copy of, the FE collection used by global_fes.

Definition at line 46 of file pfespace.cpp.

mfem::ParFiniteElementSpace::ParFiniteElementSpace	(	ParMesh *	pm,
		const FiniteElementCollection *	f,
		int	dim = `1`,
		int	ordering = `Ordering::byNODES`
	)

Definition at line 62 of file pfespace.cpp.

mfem::ParFiniteElementSpace::ParFiniteElementSpace	(	ParMesh *	pm,
		NURBSExtension *	ext,
		const FiniteElementCollection *	f,
		int	dim = `1`,
		int	ordering = `Ordering::byNODES`
	)

Construct a NURBS FE space based on the given NURBSExtension, ext.

The parameter ext will be deleted by this constructor, replaced by a ParNURBSExtension owned by the ParFiniteElementSpace.

Note: If the pointer ext is NULL, this constructor is equivalent to the standard constructor with the same arguments minus the NURBSExtension, ext.

void mfem::ParFiniteElementSpace::GetTrueTransferOperator	(	const FiniteElementSpace &	coarse_fes,
		OperatorHandle &	T
	)		const

virtual

Construct and return an Operator that can be used to transfer true-dof data from coarse_fes, defined on a coarse mesh, to this FE space, defined on a refined mesh.

This method calls GetTransferOperator() and multiplies the result by the prolongation operator of coarse_fes on the right, and by the restriction operator of this FE space on the left.

The Operator::Type of T can be set to request an Operator of the set type. In serial, the supported types are: Operator::MFEM_SPARSEMAT and Operator::ANY_TYPE (matrix-free). In parallel, the supported types are: Operator::Hypre_ParCSR and Operator::ANY_TYPE. Any other type is treated as Operator::ANY_TYPE: the operator representation choice is made by this method.
