Apply new external force over measured kinematics and GRFs
Hi, I am trying to make CMC simulations for normal walking, with an external force applied on the pelvis, which would eventually vary within the gait cycle. To simplify for now, I apply a constant vertical force 300 N on the pelvis COM. Ultimately, I wish to compute the metabolic cost using differen...

Static Optimization vs CMC
Hi, I have been wondering the difference between Static optimization (SO) and CMC, as the faster SO seems to yield similar results to CMC in many cases even if it is neglecting muscle activation dynamics. Why would someone want to consider muscle activation dynamics (thus use CMC) for walking, where...

Cannot open .osim models
Hi, I am using OpenSim4.1. I am having trouble opensim .osim model files downloaded. The project was originally from OpenSim 3.3. The error message says : Cannot open file PATH_TO_FILE. It may not exist or you do not have the permission to read it. Thrown at object.cpp: 105 in Object(). Is there a w...
