There are 6 different ways to divide this wedge element up into 3 tetrahedra, but I'll give one here. The others are very similar.

Element 1 : Nodes 1,6,2,3 Element 2 : Nodes 4,2,6,5 Element 3 : Nodes 4,6,2,1

If you are doing this to a whole mesh of wedge elements, you must remember that the edges across the 4 noded wedge faces must match.

Good luck.
