specify the number of tetrahedra a hexahedron will be split into. If the specified method does
not allow to get a conform mesh, a generic solution is applied: an additional node
is created at the gravity center of a hexahedron, serving an apex of tetrahedra, all quadrangle sides of the hexahedron are split into two triangles each serving a base of a new tetrahedron.</li>
