A Circle To Curve Contact Force generates a force between a circle (or a sphere) and a curve.
•The circle and the curve 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 curve is approximated as multi lines as shown in Figure 1. If the user increase the number of lines, the approximated contact geometry can be close to the real curve.
