Detailed Description

Representation of a three-dimensional tetrahedral mesh.

Tetrahedral meshes are represented by a hierarchy of geometric objects: vertices are at the lowest level, edges consist of vertices, faces consist of edges, and tetrahedra consist of faces. Functions like getvertices_tet3d or getedges_tet3d are provided to skip levels of the hierarchy in order to obtain the vertices or edges of a tetrahedron.

Field Documentation

uint(* f)[3]

Edges on a triangular face.

If this is a boundary face, we assume that the faces are oriented counter-clockwise as seen from the outside of the mesh. This property is ensured by the function fixnormals_tet3d and is used in the computation of outer normal vectors.
