Hi,

I am wondering whether someone out there can help me.

I have project which aims to model the 3D knee joint as realistic as
possible: 3D artificulation surfaces, ligaments, muscles with wrapping
points, patella, etc. I want to calculate the contact point and contact
forces once the muscle activations are specified.

I would think there are 6 d.o.f in the knee, and due to the constraints
of muscle forces, ligaments, etc., the joint angle and contact points
would be determined. My difficulty is how to device a surface contact
algorithm for this task and how to do it, via a commerical package, or
programming in C? Another difficulty is that the soft tissues wrap
around the the bones, so the line of action is changeing during motion.

Are there any packages avaiable or any reference papers for these
probelms?

Thanks for your kind help in advance.
