Example: Rigid Sphere Impacts Plate

Filename: contact_entity.sphere.k

A rigid sphere drops onto an elastic plate. The sphere contains shell elements
automatically generated with a "Geometric Contact Entity" spherical surface.

The plate of elastic material measures 40 * 40 * 2 mm3 and contains
64 Belytschko-Tsay shell elements. The sphere has a radius of 6.0 mm and the
distance from the center of the cube to the plate is 8.5 mm. The inertia
properties of the sphere are defined by the properties of the rigid brick
element. A geometric contact entity defines the spherical contact surface.
The sphere moves toward the plate with a uniform motion. The termination time
is 0.0005 seconds.

The Geometric Contact Entity defines the outer master surface on the rigid
sphere (*CONTACT_ENTITY). The nodes on the plate are slave nodes
(*SET_NO DE_LIST), and are in the "Geometric Entity". A load curve definition
defines the movement of the sphere (* BOUNDARY_PRESCRIBED_MOTION_RIGID,
*DEFINE_CURVE). The displacement condition for rigid bodies is input by part
number, not by listing the nodes included in the definition.
