Detailed Description

MeshViz Defines an tetrahedron cell of a volume mesh.

A tetrahedron cell has 4 facets, 6 edges and 4 nodes. Each facet is a triangle. The 3 first indices defines a facet oriented towards the interior of the cell.

Facets, nodes and edges are numbered as following :

               2
               x
              /|\
             / | \
            /  |  \        facet 0 = 012  edge 0 = 01
           /   |   \       facet 1 = 023  edge 1 = 12
          /    |    \      facet 2 = 031  edge 2 = 20
