The Hexahedron

The reference hexahedron is described as the set of points: $\begin{displaymath}He_{ref} = \{(r,s,t) \vert -1 \leq r,s,t \leq 1\}\end{displaymath}$

The reference hexahedron is mapped to a straight-sided physical hexahedron by:

The tensor element is mapped to the reference hexahedron by the identity.
