I am a PhD student in Biomedical Engineering and I changed the mass of a body via xml and now I need to evaluate the muscle strength of the biceps in a flexion movement (.mot) . However, the graph plot does not change with the change in hand mass. I ask this because in place of the hand I will put a prosthesis and this prosthesis will have a weight. Does anyone know how to change body mass and generate muscle strength graphs? I'm working with the model arm26.osim
