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 / | \ facet 3 = 132 edge 3 = 03 0 x------|------x 1 edge 4 = 13 \ | / edge 5 = 23 \ | / \ | / \ | / \ | / \|/ x 3
