Hello everybody,

I'am new to Opensim and want to validate my muscle model(wich i got in Matlab) with OpenSim.

For that i have choosen the model from https://simtk.org/projects/hand_muscle . As input i have got a set of generalized coordinates in .mat format. Now i want to pass them from Matlab to Opensim to calculate a set of muscle forces.

Is there an easy way to do that?


Any help is much appreciated.

You can use Static Optimization

Thank you for your reply!

I couldn't figure out how to pass the coordinates from Matlab to OpenSim so I changed the .mat file to a motion file and feed it to OpenSim normally. Now I'm struggeling with SO.

When I press run for SO, OpenSim freezes and doesnt give me any Information about the progress (no red sign in the corner, no progress bar or error Message). What can i do to find out what I did wrong?

Thank You

Niklas

There is a message window were you can read the status of SO. If you can post the message maybe we can tell you were it got studied. It is possible that it got stuck because of filtering the kinematics, if the motion is long or if it has many time instances.
