Enumeration Type Documentation

enum mfem::AssemblyLevel

strong

Enumeration defining the assembly level for bilinear and nonlinear form classes derived from Operator.

Enumerator
LEGACY	In the case of a BilinearForm LEGACY corresponds to a fully assembled form, i.e. a global sparse matrix in MFEM, Hypre or PETSC format. In the case of a NonlinearForm LEGACY corresponds to an operator that is fully evaluated on the fly. This assembly level is ALWAYS performed on the host.
LEGACYFULL	Deprecated: Use LEGACY instead.
FULL	Fully assembled form, i.e. a global sparse matrix in MFEM format. This assembly is compatible with device execution.
ELEMENT	Form assembled at element level, which computes and stores dense element matrices.
PARTIAL	Partially-assembled form, which computes and stores data only at quadrature points.
NONE	"Matrix-free" form that computes all of its action on-the-fly without any substantial storage.

Definition at line 30 of file bilinearform.hpp.

enum mfem::BlockInverseScaleJob

strong

Enumerator
MATRIX_ONLY
RHS_ONLY
MATRIX_AND_RHS

Definition at line 840 of file hypre.hpp.

enum mfem::ElementDofOrdering

strong

Constants describing the possible orderings of the DOFs in one element.

Enumerator
NATIVE	Native ordering as defined by the FiniteElement. This ordering can be used by tensor-product elements when the interpolation from the DOFs to quadrature points does not use the tensor-product structure.
LEXICOGRAPHIC	Lexicographic ordering for tensor-product FiniteElements. This ordering can be used only with tensor-product elements.

Definition at line 66 of file fespace.hpp.

enum mfem::ErrorAction

Action to take when MFEM encounters an error.

Enumerator
MFEM_ERROR_ABORT	Abort execution using abort() or MPI_Abort(). This is the default error action when the build option MFEM_USE_EXCEPTIONS is set to NO.
MFEM_ERROR_THROW	Throw an ErrorException. Requires the build option MFEM_USE_EXCEPTIONS=YES in which case it is also the default error action.

Definition at line 26 of file error.hpp.

enum mfem::FaceType : bool

strong

An enum type to specify if interior or boundary faces are desired.

Enumerator
Interior
Boundary

Definition at line 45 of file mesh.hpp.

enum mfem::L2FaceValues : bool

strong

An enum type to specify if only e1 value is requested (SingleValued) or both e1 and e2 (DoubleValued).

Enumerator
SingleValued
DoubleValued

Definition at line 105 of file restriction.hpp.

enum mfem::MemoryClass

strong

Memory classes identify sets of memory types.

This type is used by kernels that can work with multiple MemoryTypes. For example, kernels that can use DEVICE or MANAGED memory types should use MemoryClass::DEVICE for their inputs.

Enumerator
HOST	Memory types: { HOST, HOST_32, HOST_64, HOST_DEBUG, HOST_UMPIRE, HOST_PINNED, MANAGED }

SparseMatrix * mfem::BuildNormalConstraints	(	FiniteElementSpace &	fespace,
		Array< int > &	constrained_att,
		Array< int > &	constraint_rowstarts,
		bool	parallel = false
	)

Build a matrix constraining normal components to zero.

Given a vector space fespace, and the array constrained_att that includes the boundary attributes that are constrained to have normal component zero, this returns a SparseMatrix representing the constraints that need to be imposed.

Each row of the returned matrix corresponds to a node that is constrained. The rows are arranged in (contiguous) blocks corresponding to a physical constraint; in 3D, a one-row constraint means the node is free to move along a plane, a two-row constraint means it is free to move along a line (e.g. the intersection of two normal-constrained planes), and a three-row constraint is fully constrained (equivalent to MFEM's usual essential boundary conditions).

The constraint_rowstarts array is filled in to describe the structure of these constraints, so that (block) constraint k is encoded in rows constraint_rowstarts[k] to constraint_rowstarts[k + 1] - 1, inclusive, of the returned matrix.

Constraints are imposed on "true" degrees of freedom, which are different in serial and parallel, so we need different numbering systems for the serial and parallel versions of this function.

When two attributes intersect, this version will combine constraints, so in 2D the point at the intersection is fully constrained (ie, fixed in both directions). This is the wrong thing to do if the two boundaries are (close to) parallel at that point.

Parameters

[in]	fespace	A vector finite element space
[in]	constrained_att	Boundary attributes to constrain
[out]	constraint_rowstarts	The rowstarts for separately eliminated constraints, possible input to EliminationCGSolver
[in]	parallel	Indicate that fespace is actually a ParFiniteElementSpace and the numbering in the returned matrix should be based on truedofs.

Returns

a constraint matrix

void mfem::CalcGradTensor	(	const FiniteElement &	fe,

store gradient matrix G for each integration point on the reference element. For tensor product evaluation, this is only called on the 1D reference element, and higher dimensions are put together from that. The element stiffness matrix can be written

\[ S_E = \sum_{k=1}^{nq} G_{k,i}^T (D_E^G)_{k,k} G_{k,j} \]

where \( nq \) is the number of quadrature points, \( D_E^G \) contains all the information about the element geometry and coefficients (Jacobians etc.), and \( G \) is the matrix built in this routine, which is the same for all elements in a mesh.

Parameters

	fe	the element we are calculating on
	ir	the integration rule to calculate the gradients on
[out]	G	must be (nip x dim x dof) with column major storage
[in]	dof_map	the inverse of dof_map is applied to reorder local dofs.

void mfem::CalcShapeMatrix	(	const FiniteElement &	fe,

Store mass-like matrix B for each integration point on the reference element. For tensor product evaluation, this is only called on the 1D reference element, and higher dimensions are put together from that. The element mass matrix can be written \( M_E = B^T D_E B \) where the B built here is the B, and is unchanging across the mesh. The diagonal matrix \( D_E \) then contains all the element-specific geometry and physics data.

Parameters

B	must be (nip x dof) with column major storage

Shallow or deep copy src to dst with the goal to make the array src accessible through dst with the MemoryClass dst_mc. If one of the host/device MemoryTypes of src is contained in dst_mc, then a shallow copy will be used and dst will simply be an alias of src. Otherwise, dst will be properly allocated and src will be deep copied to dst.

If dst_owner is set to true and shallow copy is being used, then dst will not be an alias of src; instead, src is copied to dst and all ownership flags of src are reset.

In both cases (deep or shallow copy), when dst is no longer needed, dst.Delete() must be called to ensure all associated memory allocations are freed.

The input contents of dst, if any, is not used and it is overwritten by this function. In particular, dst should be empty or deleted before calling this function.
