A Surface To Surface Contact generates a force between one surface and the other surface.
•Two surfaces 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.
•The action surface is approximated as multi points as shown in Figure 1 only the points can be contacted with the specified base patches.
