SimplicialMeshCellBase_3 Concept Reference

Definition

The concept SimplicialMeshCellBase_3 describes the requirements for the TriangulationDataStructure_3::Cell type of the triangulation used in a 3D simplicial mesh data structure.

The type SimplicialMeshCellBase_3 refines the concept TriangulationCellBase_3 and must be copy constructible. The concept SimplicialMeshCellBase_3 includes a way to store and retrieve if a given cell of the triangulation is inside a subdomain or not, and which subdomain it belongs to in case of a multi-domain.

Moreover, this concept adds four markers per cell to mark the facets of the triangulation that are surface facets.

Types
typedef unspecified_type	Subdomain_index
	Type of indices for cells of the mesh complex.
typedef unspecified_type	Surface_patch_index
	Type of indices for surface patches of the mesh complex.

Operations
Subdomain_index	subdomain_index ()
	returns the index of the input subdomain that contains the cell.
void	set_subdomain_index (Subdomain_index index)
	Sets the subdomain index of the cell.
bool	is_facet_on_surface (int i)
	returns true iff facet(i) is a surface facet.
Surface_patch_index	surface_patch_index (int i)
	returns Surface_patch_index of facet i.
void	set_surface_patch_index (int i, Surface_patch_index index)
	sets Surface_patch_index of facet i to index.
