Hey all, i have a problem about the path file (<controls_file>) for <PrescribedController>. I want to change the file path to relativ path file , so that it can be opened, if i send the model data to somebody without any changes to the file path in the model file. (The path file below is path file t...

Hello, Right now i want to do a CMC (Computed Muscle Control) simulation to get the needed muscle forces under consideration of external torque in Opensim programm. So this external torque (as a function of the input kinematics) will work as an additional actuator to the osim model while simulating ...

Hello, i have a problem with the output of the muscle activation when using CMC. Here i simulated the elbow movement of flexion with and without exoskeleton with CMC. The external loads are just the actuator torque from the exoskeleton on elbow for flexion movement (applied on ulna and express in gr...

Hello, Right now i want to do a CMC (Computed Muscle Control) simulation to get the needed muscle forces under consideration of external torque in simulink. So this external torque (as a function of the input kinematics) will help the osim model to tracking the given reference/input kinematics. But ...

Did you perform Joint Reaction Analysis using the Analyze Tool after simulation? Or did you attach the Joint Reaction Analysis to your CMC Tool? It would also be good to check that the point of application of the force is at the pin joint's location. thanks for answering my question. I performed Jo...

Hello all, I have problem with my joint reaction analysis' result. To validate the result i plot the torque in all direction (x, y, z axis) and see if torque in z axis (Mz) is 0 during the elbow flexion. But the curve of Mz is not completely 0 during the movement. It starts with a high torque and go...

px, py, and pz are the coordinates of the location at which the force vector is applied. The location of px, py, and pz would affect the torque vector (since the torque vector is calculated such that the system is an equivalent system). If these are all 0, sounds like the force is applied at the bo...

Hello all, I have a question about 1 type of the output from Joint reaction analysis . From the OpenSim Documentation and from the OpenSim youtube webinar the outputs from the joint reaction analysis are only the 3 force vectors in x,y,z axis and 3 torques in x,y,z axis , but i get another type of o...
