Detailed Description

Mesh connectivity stores a sparse data structure of connections (incidence relations) between mesh entities for a fixed pair of topological dimensions.

The connectivity can be specified either by first giving the number of entities and the number of connections for each entity, which may either be equal for all entities or different, or by giving the entire (sparse) connectivity pattern.

Member Function Documentation

◆ init() [1/2]

void MeshConnectivity::init	(	std::size_t	num_entities,
		std::size_t	num_connections
	)

Initialize number of entities and number of connections (equal for all)

◆ init() [2/2]

void MeshConnectivity::init ( std::vector< std::size_t > & num_connections )

Initialize number of entities and number of connections (individually)

◆ set() [1/2]
