File Information
Description

This file contains example contact forces built for SimMechanics and a set of demonstration models showing how to use them. Combining these fundamental contact forces enables you to model contact forces between more complex geometrical shapes. A few simple demonstration models are provided to get you started.
In addition, a model implementing a 9-hole miniature golf course is included. This shows how you can easily build up a set of components and reuse them in different designs.

Please read the README.txt file to get started.

Aditya -- no low pass filter is required, so no I'm not using one. Some form of delay would be required if the formulation I used created an algebraic loop in Simulink, but the way I modeled it no loop is created.

Hi Steve,
Great model.
In the contact force model it does not seem like you are using the low pass filter? Is that the case.
