Detailed Description

MeshViz Defines an hexahedron cell of a volume mesh.

An hexahedron cell has 6 facets which can be in any plane of the 3D space. Each facet is a quadrangle not necessarily a square. The 4 first indices defines a facet oriented towards the interior of the cell.

Facets, nodes and edges are numbered as following :

                          4-----------7   facet 0 = 0374  edge 0 = 01
                         /|          /|   facet 1 = 1562  edge 1 = 12
                       /  |        /  |   facet 2 = 0451  edge 2 = 23
                     /    |      /    |   facet 3 = 3267  edge 3 = 30
                    5----------6      |   facet 4 = 0123  edge 4 = 45
                    |     |    |      |   facet 5 = 4765  edge 5 = 56
                    |     0----|------3                   edge 6 = 67
