Inverse Dynamics Crashing

I have a simple right leg model with 3 muscles (bothlegs.osim simplified). I have a .mot file specifying degrees of freedom that I can get to move the model. However, when I try to do Inverse Dynamics I can't get it to run. Any ideas why? Do I have to have external forces?

Hi Anne,
Do you have masses/inertia for all bodies? The model provided with OpenSim does not have any. You don't have to have external forces (Arm26 example doesn't either).

You're right! I think the patella has 0 mass. I'll double check that.
