Detailed Description

Defines a wedge cell of a volume mesh.

A wedge cell has 5 facets which can be in any plane of 3D space. It has 2 triangle facets and 3 quadrangle facets. The 3 first indices define a triangle facet oriented towards the interior of the cell.

Facets, nodes, and edges are numbered as follows:

                                  n2               facet 0 = 012   edge 0 = 01
