Re: Static Optmization Constrain Violation = -1
Alternatively since I have the velocity and acceleration at the joints recorded in my experimental data, would adding it to the .mot file solve the problem?

Re: Static Optmization Constrain Violation = -1
Also when I run it, the model does not follow the input motion and direction while the Inverse Dynamics followed it. The muscles also dont stay connected to the bones but seem to extend well beyond the body of the model.

Static Optmization Constrain Violation = -1
Hi Ayman. I am running the modified model that you had helped me create previously, in version 2.4. It works and generates an ID output. However when I run Static Optimization on it, at everystep I get the message constraint violation = -1 #ND What does the error mean? I understand that large constr...

RE: A body between two joints.
I am currently replacing all the fixed joints in the model with weldjoints. Will that solve the problem?

RE: A body between two joints.
I didnt understand completely what you meant about the joint's deviation coordinate.
