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 x facet 1 = 354 edge 1 = 12 . / \ facet 2 = 0253 edge 2 = 20 . / \ facet 3 = 1452 edge 3 = 34 . / \ facet 4 = 0341 edge 4 = 45 . / \ edge 5 = 53 n5 / \ edge 6 = 03 x / \ edge 7 = 14 / \ n0 x-------------x n1 edge 8 = 25 / \ . . / \. . / . \ . / . \ . /. \ . n3 x-------------x n4
