Geometric Contact Entity
\$
\$  LSTC Example
\$
\$  * Part 1 - plate
\$      Shells (2.0 mm thick)
\$      elastic material
\$      translational constraints on all four edges (z-dir only)
\$
\$  * Part 2 - sphere  -  Contact Entity
\$      Defined as shells and rigid material but really there are no part 2
\$        elements defined explicitly.  The contact entity is really part 2.
\$      center (x,y,z) = (20,20,9)
\$
\$
\$  ===> Due to the course mesh of the plate, there is considerable amount
\$         of penetration of the sphere into the plate.
