Is there a way to calculate the forces each muscle is applying in a movement?

Provide easy-to-use, extensible software for modeling, simulating, controlling, and analyzing the neuromusculoskeletal system.

Apologies, but I am a little new to OpenSim and biomechanical simulation.

I have done some of the beginner tutorials on Inverse Kinematics and Dynamics. I understand the result of these workflows is the net force and moments of the muscles at each joint, but not the individual forces each muscle at a joint is applying. Is it possible to calculate this?

Hello,

If you only need the magnitudes of the forces applied by the muscles then you can use a ForceReporter (Documentation here https://simtk.org/api_docs/opensim/api_ ... orter.html).

Hope this helps,
