I was wondering if any of you would help me. I am creating a simple FDK model using wrapping muscles and I am getting the following error " Too small steps for GSS search causes looping of Newton method ". I have two wrap muscles, and it seems one of them “supraspinatus” is causing the issue because when I turn it off Inverse Dynamics work just fine.
I have attached the code and I would really appreciate it if someone can run it and give me their feedback ASAP. It is a really simple model anyhow.
