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)
$ radius = 6 mm
$
$
$ ===> Due to the course mesh of the plate, there is considerable amount
$ of penetration of the sphere into the plate.
