Hi Felix,

It is not possible based on any error message to say if the gearing should go up it depends on the nature the FDK dof in the model. The idea is that you would want a perturbation on any...

Hi John,

Which AMMR model are you referring to?

The normal knee model do not have a patella/femur stiffness implemented, it is made with kinematic constraints.
