◆ v_GetDir()

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

protectedvirtual

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

◆ v_GetEdgeFaceMap()

int Nektar::SpatialDomains::PrismGeom::v_GetEdgeFaceMap	(	const int	i,
		const int	j
	)		const

protectedvirtual

Returns the standard element edge IDs that are connected to a given face.

For example, on a prism, edge 0 is connnected to faces 0 and 1; GetEdgeFaceMap(0,j) would therefore return the values 0 and 1 respectively. We assume that j runs between 0 and 1 inclusive, since every face is connected to precisely two faces for all 3D elements.

This function is used in the construction of the low-energy preconditioner.

Parameters

i	The edge to query connectivity for.
j	The local face index between 0 and 1 connected to this element.

◆ v_GetVertexEdgeMap()

int Nektar::SpatialDomains::PrismGeom::v_GetVertexEdgeMap	(	const int	i,
		const int	j
	)		const

protectedvirtual

Returns the standard element edge IDs that are connected to a given vertex.

For example, on a prism, vertex 0 is connnected to edges 0, 3, and 4; GetVertexEdgeMap(0,j) would therefore return the values 0, 1 and 4 respectively. We assume that j runs between 0 and 2 inclusive, which is true for every 3D element asides from the pyramid.

This function is used in the construction of the low-energy preconditioner.

Parameters

i	The vertex to query connectivity for.
j	The local edge index between 0 and 2 connected to this element.

◆ v_GetVertexFaceMap()

int Nektar::SpatialDomains::PrismGeom::v_GetVertexFaceMap	(	const int	i,
		const int	j
	)		const

protectedvirtual

Returns the standard element face IDs that are connected to a given vertex.

For example, on a hexahedron, vertex 0 is connnected to faces 0, 1, and 4; GetVertexFaceMap(0,j) would therefore return the values 0, 1 and 4 respectively. We assume that j runs between 0 and 2 inclusive, which is true for every 3D element asides from the pyramid.

This is used in the construction of the low-energy preconditioner.

Parameters

i	The vertex to query connectivity for.
j	The local face index between 0 and 2 connected to this element.
