NAME
prism - Prism reference element
DESCRIPTION
The prism reference element is
K = { 0 < x < 1 and 0 < y < 1-x and -1 < z < 1 }
NUMBERING
The orientation is such that triedra (01, 02, 03) is direct and all faces, see from exterior, are in the direct sens. References: P. L. Georges, "Generation automatique de maillages", page 24-, coll RMA, 16, Masson, 1994.
