A Sphere To Surface Contact generates a force between one surface and the other sphere.
•The sphere and the surface must belong to two different bodies.
•The contact force can be not only linear or exponential but also nonlinear spline characteristics to the contact penetration and its velocity.
•The base surface is approximated as multi triangular patches as shown in Figure 1.
