Geometric Entity Counters

The following geometric entity counter methods are available:

Table 3-20: Geometric Entity Counter Methods

method	1D	2d	3d	output type	3.5a name
getNEntities()	√	√	√	int[]
getNVertices()	√	√	√	int	nv, flgeomnv
getNEdges()	√	√	√	int	ne, flgeomnes
getNFaces()			√	int	nf
getNBoundaries()	√	√	√	int	nbs, flgeomnbs
getNDomains()	√	√	√	int	ns, flgeomnmr
getNEntitiesMesh()	√	√	√	int[]

•	getNEntities returns a vector of length 2 in 1D, length 3 in 2D, and length 4 in 3D. The vectors contain the number of geometric entities for each entity dimension. The methods getNVertices, getNEdges, getNFaces, getNBoundaries, and getNDomains return the number of entities of the specified type.

•

getNEntitiesMesh returns a vector of length 2 in 1D, length 3 in 2D, and length 4 in 3D. The vectors contain the number of geometric entities for each entity dimension in the geometry used for meshing. If there are no mesh control entities in the geometry, the output is identical to that of getNEntities.
