Hello there,

May some one tell me whether the moment arms in OpenSim, calculated with the Analyze tool > MomentArms are calculated in the parent or child frame?

Thank you best,

Hi, Thanks for the help! May you explain me furthermore how I know the new values in the .xml file for tendon-slack-length and optimal-fiber-length as well as pennetration-angle-at-optimal? Because my aim is to add a new TFL that is shortened and transfered to the femur head as insertion point. Or h...

Hello,

I'm trying to create an additional TFL muscle to my gait model. Although I know how to transfer the actual one, I might not be able to add a new muscle to the model.
Could someone tell me where I can find the necessary tools in OpenSim to do so?

Thanks!

Hi there,

I have the same goal to extract the moment arms over the time. But I don't get how to read them out after doint the MuscleAnalysis, i.e. how are these files then called? I see many fiber lengths and forces but no moment arms.

Thank you best in advance for the help.
