Classes
class	Mesh
struct	Mesh::PeriodicPair
	A periodic pair of boundary zones: zone_b is zone_a translated by translation. More...
struct	Mesh::BoundaryFace
	A boundary face (2 nodes in 2D; 3 or 4 nodes in 3D) and its zone name. More...

Typedefs
using	Stretching = std::array< rtype, 3 >
	Tanh stretching factor of each direction of a generated mesh, 0 for uniform spacing.

Enumerations
enum class	MeshType {   FROM_FILE , CARTESIAN , CARTESIAN_TRI , WEDGE ,   CARTESIAN_TET , CARTESIAN_PRISM , CARTESIAN_PYRAMID , CARTESIAN_MIXED }
enum class	CellType {   TRIANGLE , QUAD , TETRAHEDRON , PYRAMID ,   PRISM , HEXAHEDRON }

Functions
const std::vector< std::vector< uint8_t > > &	cell_local_faces (uint32_t n_nodes)
	Local faces of a positively oriented 3D cell with n_nodes nodes (4 tetrahedron, 5 pyramid, 6 prism, 8 hexahedron; Gmsh/VTK node order), each ordered so its right-hand normal points out of the cell.
void	cell_tetrahedra (const std::vector< std::array< double, 3 > > &nodes, std::vector< std::array< std::array< double, 3 >, 4 > > &tets)
	Decompose a 3D cell (node coordinates in Gmsh/VTK order, positively oriented) into tetrahedra: each face is fanned around its vertex average and joined to the cell's vertex average. This is the decomposition that defines the mesh's cell volumes and centroids.

Function Documentation

cell_local_faces()

const std::vector< std::vector< uint8_t > > & cell_local_faces

(

uint32_t

n_nodes

)

Local faces of a positively oriented 3D cell with n_nodes nodes (4 tetrahedron, 5 pyramid, 6 prism, 8 hexahedron; Gmsh/VTK node order), each ordered so its right-hand normal points out of the cell.

cell_tetrahedra()

void cell_tetrahedra	(	const std::vector< std::array< double, 3 > > &	nodes,
		std::vector< std::array< std::array< double, 3 >, 4 > > &	tets
	)

Decompose a 3D cell (node coordinates in Gmsh/VTK order, positively oriented) into tetrahedra: each face is fanned around its vertex average and joined to the cell's vertex average. This is the decomposition that defines the mesh's cell volumes and centroids.
