class	ParMortarAssembler
	This class implements the parallel variational transfer between finite element spaces. Variational transfer has been shown to have better approximation properties than standard interpolation. This facilities can be used for supporting applications which require the handling of non matching meshes. For instance: General multi-physics problems, fluid structure interaction, or even visualization of average quantities within subvolumes. This particular code is also used with LLNL for large scale multilevel Monte Carlo simulations. This algorithm allows to perform quadrature in the intersection of elements of two separate, unrelated, and arbitrarily distributed meshes. It generates quadrature rules in the intersection which allows us to integrate with to machine precision using the mfem::MortarIntegrator interface. See https://doi.org/10.1137/15M1008361 for and in-depth explanation. At this time curved elements are not supported. Convex non-affine elements are partially supported, however, high order (>3) finite element discretizations or nonlinear geometric transformations might generate undesired oscillations. Discontinuous fields in general can only be mapped to order 0 destination fields. For such cases localized versions of the projection will have to be developed. More...

strong

Enumeration defining the assembly level for bilinear and nonlinear form classes derived from Operator. For more details, see https://mfem.org/howto/assembly_levels.

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.

Defines the bounding box for the face patches used by NewZZErorrEstimator.

By default, BoundingBox(...) computes the parameters of a minimal bounding box for the given face_patch that is aligned with the physical (i.e. global) Cartesian axes. This means that the size of the bounding box will depend on the orientation of the patch. It is better to construct an orientation-independent box. This is implemented for 2D patches. The parameters angle and midpoint encode the necessary additional geometric information.

@a iface     : Index of the face that the patch corresponds to.
               This is used to compute @a angle and @a midpoint.

@a angle     : The angle the patch face makes with the x-axis.

BuildNormalConstraints()

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.

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

HypreParMatrixFromBlocks()

HypreParMatrix * mfem::HypreParMatrixFromBlocks	(	Array2D< HypreParMatrix * > &	blocks,
		Array2D< double > *	blockCoeff = NULL
	)

Returns a merged hypre matrix constructed from hypre matrix blocks.

It is assumed that all block matrices use the same communicator, and the block sizes are consistent in rows and columns. Rows and columns are renumbered but not redistributed in parallel, e.g. the block rows owned by each process remain on that process in the resulting matrix. Some blocks can be NULL. Each block and the entire system can be rectangular. Scalability to extremely large processor counts is limited by global MPI communication, see GatherBlockOffsetData() in hypre.cpp.

Definition at line 3020 of file hypre.cpp.

HypreStealOwnership()

void mfem::HypreStealOwnership	(	HypreParMatrix &	A_hyp,

Make A_hyp steal ownership of its diagonal part A_diag.

If A_hyp does not own I and J, then they are aliases pointing to the I and J arrays in A_diag. In that case, this function swaps the memory objects. Similarly for the data array.

After this function is called, A_hyp will own all of the arrays of its diagonal part.

Note

I and J can only be aliases when HYPRE_BIGINT is disabled.

WriteVTKEncodedCompressed.

Definition at line 654 of file vtk.cpp.

WriteBinaryOrASCII()

template<typename T >

void mfem::WriteBinaryOrASCII	(	std::ostream &	os,
		std::vector< char > &	buf,
		const T &	val,
		const char *	suffix,
		VTKFormat	format
	)

Write either ASCII data to the stream or binary data to the buffer depending on the given format.

If format is VTK::ASCII, write the canonical ASCII representation of val to the output stream. Subnormal floating point numbers are rounded to zero. Otherwise, append its raw binary data to the byte buffer buf.

Note that there are specializations for uint8_t (to write as a numeric value rather than a character), and for float and double values to use the precision specified by format.

Definition at line 147 of file vtk.hpp.

WriteBinaryOrASCII< double >()

template<>

void mfem::WriteBinaryOrASCII< double >	(	std::ostream &	os,
		std::vector< char > &	buf,
		const double &	val,
		const char *	suffix,
		VTKFormat	format
	)

Specialization of WriteBinaryOrASCII for double.

If format is equal to VTKFormat::BINARY32, val is converted to a float and written as 32 bits. Subnormals are rounded to zero in ASCII output.

Definition at line 626 of file vtk.cpp.

WriteBinaryOrASCII< float >()

template<>

void mfem::WriteBinaryOrASCII< float >	(	std::ostream &	os,
		std::vector< char > &	buf,
		const float &	val,
		const char *	suffix,
		VTKFormat	format
	)

Specialization of WriteBinaryOrASCII<T> for float.

If format is equal to VTKFormat::BINARY, val is converted to a double and written as 64 bits. Subnormals are rounded to zero in ASCII output.

Definition at line 645 of file vtk.cpp.

WriteBinaryOrASCII< uint8_t >()

template<>

void mfem::WriteBinaryOrASCII< uint8_t >	(	std::ostream &	os,
		std::vector< char > &	buf,
		const uint8_t &	val,
		const char *	suffix,
		VTKFormat	format
	)

Specialization of WriteBinaryOrASCII for uint8_t to ensure ASCII output is numeric (rather than interpreting val as a character.)

Definition at line 617 of file vtk.cpp.

WriteVTKEncodedCompressed()

void mfem::WriteVTKEncodedCompressed	(	std::ostream &	os,
		const void *	bytes,
		uint32_t	nbytes,
		int	compression_level
	)

Outputs encoded binary data in the base 64 format needed by VTK.

The binary data will be base 64 encoded, and compressed if compression_level is not zero. The proper header will be prepended to the data.
