Hello, I'm stumped by what is probably a simple error somewhere in a very basic inverse dynamics + static optimisation simulation I'm trying. I add .mot kinematics to a model, add .mot GRF associated motion data (all seems fine to that point), then give those GRFs settings for expressed in/applied t...
