Example: Rigid Wall Sphere Impacts a Plate

Filename: rigidwall_geometric_sphere.plate.k

Description:
A " Stonewall" - sphere impacts an elastic plate. (The sphere will not be shown
in LSTAURUS.)

Model:
The plate has an elastic material model with Belytschko-Tsay shell formulation.
The plate is 40 * 40 * 2 mm3. The sphere has a radius of 8 mm and its center is
9 mm above the plate. The sphere moves towards the plate with a prescribed
displacement resulting in a velocity of velocity of 3 mm/second.

Input:
A spherical stonewall surface represents the true geometry of the ball.
(*RIGIDWALL_GEOMETRIC_SPHERE_MOTION). The stone wall cards contain direction
and load curve number defining the motion. All nodes of the plate are prevented
from penetrating the sphere.
