Hey guys, Quick question: we're trying to run inverse dynamics for some running simulations with a full-body model (including arms), but didn't bother to fit the arm motions in inverse kinematics. Does the OpenSim inverse dynamics tool run classical inverse dynamics where the inertia of bodies above...

Thank you for sharing this excellent tool! I would like to add some features to the OpenSim model. Could you possibly also share the matlab compiling commands you used to create the .mexw32 function?

Thank you!

This is the easiest method.

The first link is probably easier.

Hey James, Thanks for the response. It did help. However, I have encountered another problem. The Matlab API is returning 'NaN' for all muscle moment arm values about the MTP joint (OpenSim 2392 model with Chand John's walking data; the MTP joint angle is constant). The OpenSim GUI plot function ret...

Hello everyone, I am trying to extract muscle properties and moment arms from an OpenSim model across a dynamic task. I have prescribed a motion for the model using the example script 'prescribeMotionInModel.m', but I do not understand how to cycle through the states of the motion in order to extrac...
