Member Function Documentation

◆ addElement()

void smith::Domain::addElement	(	int	geom_id,
		int	elem_id,
		mfem::Geometry::Type	element_geometry
	)

Add an element to the domain.

This is meant for internal use on the class. Prefer to use the factory methods (ofElements, ofBoundaryElements, etc) to create domains and thereby populate the element lists.

Definition at line 268 of file domain.cpp.

◆ addElements()

void smith::Domain::addElements	(	const std::vector< int > &	geom_id,
		const std::vector< int > &	elem_id,
		mfem::Geometry::Type	element_geometry
	)

Add a batch of elements to the domain.

This is meant for internal use on the class. Prefer to use the factory methods (ofElements, ofBoundaryElements, etc) to create domains and thereby populate the element lists.

Definition at line 290 of file domain.cpp.

◆ insert_restriction()

void smith::Domain::insert_restriction	(	const fes_t *	fes,
		FunctionSpace	space
	)

create a restriction operator over this domain, using its FunctionSpace as a key

Note: if a restriction for the given key (i.e. FunctionSpace) already exists, this function does nothing

Definition at line 536 of file domain.cpp.

◆ ofBoundaryElements()

Domain smith::Domain::ofBoundaryElements	(	const mesh_t &	mesh,
		std::function< bool(std::vector< vec2 >, int)>	func

Parameters

mesh	the entire mesh
func	predicate function for determining which boundary elements will be included in this domain

Definition at line 368 of file domain.cpp.

◆ ofEdges()

	)

static

◆ ofFaces()

Domain smith::Domain::ofFaces	(	const mesh_t &	mesh,
		std::function< bool(std::vector< vec2 >, int)>	func
	)

static

◆ ofVertices()

static Domain smith::Domain::ofVertices	(	const mesh_t &	mesh,
		std::function< bool(vec2)>	func
	)

static

create a domain from some subset of the vertices in an mfem::Mesh

Parameters

mesh	the entire mesh
func	predicate function for determining which vertices will be included in this domain. The function's argument is the spatial position of the vertex.
