Re: Acceleration computation in BodyKinematic
Ah, that explains the accelerations we're getting when running BodyKinematics with only a motion imposed on the model. It's still strange though that the positions and velocities correspond to the loaded motion whereas the accelerations do not. If the accelerations are calculated from F=m*a, I'd exp...

Re: Acceleration computation in BodyKinematic
I'm facing the same problem with several OpenSim models, as well as the examples included with OpenSim. I'm trying to determine body segment COM accelerations based on a motion file alone (so, no muscle excitations). The results are unrealistic. For example, the vertical acceleration for the pelvis ...
