Detailed Description

8-noded, linear, C0 continuous finite element in 3D space.

The ordering of the nodes should be defined in the following order:

5 (0,1,1) 6 (1,1,1) *------------------------* /| /| / | / | / | / | / | / | / | (1,1,0) 7 / | (0,1,0) 4*------------------------* | | 1* ---------------- | ----*2 (1,0,1) | / (0,0,1) | / | / | / | / | / | / | / |/ |/ *------------------------* 0 3 (0,0,0) (1,0)

This is an abstract class. Specific concrete implemenations of this It must be combined with the physics component of the problem. This has already been done in the following classes:
