Hello,
I'm am trying to flex/extend the knee and leave the patella to do whatever it wants while contacting the femur. I have a muscle attached from femur to patella, patella to tibia, and between the femur and tibia. Is there anyway I can just specify the knee flexion and measure what the patella does? I don't want to specify the patellar motion. If I don't include these degrees of freedom in a .mot file the program sets them to 0, but that is not what I want. Any ideas on how to use contact? By the way, I think using the api example for the muscle tug of war is very confusing.
