[Jprogramming] Cubes

[David Ward Lambert]

Finite element codes describe "bricks", tetrahedra, quadrilaterals with
midside vertices etc. These predefine a vertex order, and then list the
nodes for each connected group.  Thus for ANSYS or abaqus you'd defined
a linear (trilinear, actually) brick using a list of 8 vertexes in a
particular order.  CalculiX is an open source FEA code.  In the theory
section in this document describes node order for the hexahedra.
