Detailed Description

MeshViz Defines a pyramid cell of a volume mesh.

A pyramid cell has 5 facets which can be in any plane of 3D space. It has 4 triangle facets and 1 quadrangle facet. The 4 first indices define the base quadrangle facet oriented towards the interior of the cell.

Facets, nodes and edges are numbered as follows:

               n4
               x                           facet 0 = 0123  edge 0 = 01
              /| \ .                       facet 1 = 041   edge 1 = 12
             / |  \   .                    facet 2 = 142   edge 2 = 23
            /  |   \     .                 facet 3 = 243   edge 3 = 30
           /   |    \       .              facet 4 = 340   edge 4 = 04
          /    |     \         .                           edge 5 = 14
         /  n3 x------\----------x n2                      edge 6 = 24
        /    '         \       '                           edge 7 = 34
