A Sphere In Box Contact generates a force between a sphere and a box.
•The sphere and box must belong to two different bodies.
•The sphere must be defined an action geometry and the cylinder must be defined a base geometry.
•The sphere must be inside of the box.
•The contact force can be not only linear or exponential but also nonlinear spline characteristics to the contact penetration and its velocity.
