Constructor & Destructor Documentation

mfem::FiniteElementSpace::FiniteElementSpace ( )

Default constructor: the object is invalid until initialized using the method Load().

Definition at line 60 of file fespace.cpp.

mfem::FiniteElementSpace::FiniteElementSpace	(	const FiniteElementSpace &	orig,
		Mesh *	mesh = `NULL`,
		const FiniteElementCollection *	fec = `NULL`
	)

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

If the mesh or fec pointers are NULL (default), then the new FiniteElementSpace 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 mesh 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 conforming prolongation and restriction matrices, and the update operator, will not be copied, even if they are created in the orig object.

Definition at line 71 of file fespace.cpp.

	)

inline

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

const Operator * mfem::FiniteElementSpace::GetElementRestriction ( ElementDofOrdering e_ordering ) const

Return an Operator that converts L-vectors to E-vectors.

An L-vector is a vector of size GetVSize() which is the same size as a GridFunction. An E-vector represents the element-wise discontinuous version of the FE space.

The layout of the E-vector is: ND x VDIM x NE, where ND is the number of degrees of freedom, VDIM is the vector dimension of the FE space, and NE is the number of the mesh elements.

The parameter e_ordering describes how the local DOFs in each element should be ordered, see ElementDofOrdering.

For discontinuous spaces, the element restriction corresponds to a permutation of the degrees of freedom, implemented by the L2ElementRestriction class.

The returned Operator is owned by the FiniteElementSpace.

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

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

It is assumed that the mesh of this FE space is a refinement of the mesh of coarse_fes and the CoarseFineTransformations returned by the method Mesh::GetRefinementTransforms() of the refined mesh are set accordingly. The Operator::Type of T can be set to request an Operator of the set type. Currently, only Operator::MFEM_SPARSEMAT and Operator::ANY_TYPE (matrix-free) are supported. When Operator::ANY_TYPE is requested, the choice of the particular Operator sub-class is left to the method. This method also works in parallel because the transfer operator is local to the MPI task when the input is a synchronized ParGridFunction.

Definition at line 2167 of file fespace.cpp.

void mfem::FiniteElementSpace::GetTrueTransferOperator	(	const FiniteElementSpace &	coarse_fes,

	)		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.

Reorder the scalar DOFs based on the element ordering.

The new ordering is constructed as follows: 1) loop over all elements as ordered in the Mesh; 2) for each element, assign new indices to all of its current DOFs that are still unassigned; the new indices we assign are simply the sequence 0,1,2,...; if there are any signed DOFs their sign is preserved.
