A volume filled with tetrahedra, for analysis and export. It fits every Mesh input.
A Tet Mesh also fits an input that takes a Mesh.
How many volume elements (hexahedra or tetrahedra) the mesh has.
Each distinct element edge as a line segment.
The outer boundary faces as a surface Mesh.
How many vertices (FE nodes) the mesh has.
The position of every vertex.
