◆ v_GetDir()

int Nektar::SpatialDomains::PyrGeom::v_GetDir	(	const int	i,

Returns the element coordinate direction corresponding to a given face coordinate direction.

◆ v_GetEdgeNormalToFaceVert()

int Nektar::SpatialDomains::PyrGeom::v_GetEdgeNormalToFaceVert	(	const int	i,
		const int	j
	)		const

protectedvirtual

Returns the standard lement edge IDs that are normal to a given face vertex.

For example, on a hexahedron, on face 0 at vertices 0,1,2,3 the edges normal to that face are 4,5,6,7, ; so GetEdgeNormalToFaceVert(0,j) would therefore return the values 4, 5, 6 and 7 respectively. We assume that j runs between 0 and 3 inclusive on a quadrilateral face and between 0 and 2 inclusive on a triangular face.

This is used to help set up a length scale normal to an face

Parameters

i	The face to query for the normal edge
j	The local vertex index between 0 and nverts on this face
