Hello, I am trying to execute the RRA tool in OpenSim. When I run the tool, my model disappears when it gets to the second or third step of computing CNC. I was wondering what the issues could possibly be. My model loads the inverse kinematics motions and I am able to perform inverse dynamics. My external forces are correct and I have followed the guide for creating a task and actuator files. I am unsure where the problem could be.
