Function Documentation

entity_closure()

template<size_t from_dim, size_t to_dim, size_t D, typename U >

std::set<size_t> flecsi::topo::unstructured_impl::entity_closure	(	const definition< D > &	md,
		U &&	indices
	)

Return the union of all vertices that are referenced by at least one of the entities in the given set of indices.

Template Parameters

by_dim

The topological dimension of the entities that reference the vertex.

Parameters

md	The mesh definition containing the topological connectivity information.
indices	The entity indeces.

entity_neighbors() [1/2]

template<size_t from_dim, size_t to_dim, size_t thru_dim, size_t D>

std::set<size_t> flecsi::topo::unstructured_impl::entity_neighbors	(	const definition< D > &	md,
		size_t	entity_id
	)

Find the neighbors of the given entity id.

Template Parameters

from_dim	The topological dimension of the entity for which the neighbor information is being requested.
to_dim	The topological dimension to search for neighbors.
thru_dim	The topological dimension through which the neighbor connection exists.

Parameters

md	The mesh definition containing the topological connectivity information.
entity_id	The id of the entity in from_dim for which the neighbors are to be found.

entity_neighbors() [2/2]

template<size_t from_dim, size_t to_dim, size_t thru_dim, size_t D, typename U , typename = std::enable_if_t<util::is_iterative_container_v<U>>>

std::set<size_t> flecsi::topo::unstructured_impl::entity_neighbors	(	const definition< D > &	md,
		U &&	indices
	)

Return the dependency closure of the given set.

Template Parameters

from_dim	The topological dimension of the entity for which the neighbor information is being requested.
to_dim	The topological dimension to search for neighbors.
thru_dim	The topological dimension through which the neighbor connection exists.

Parameters

md	The mesh definition containing the topological connectivity information.
indices	The entity indices of the initial set.
intersections	The number of intersections that constitute a neighboring entity.

entity_referencers()

template<size_t from_dim, size_t to_dim, size_t D>

std::set<size_t> flecsi::topo::unstructured_impl::entity_referencers	(	const definition< D > &	md,
