RE: EMG data in CMC and forward dynamics
Go to my simtk project, UW Cosimulation, and look under documents. There's some files on how to run forward dynamics models with EMG.

RE: stiffness in a joint
Use a Generalized Spring Force. This can be about any generalized coordinate, including rotational ones.

RE: Damper
I've added a SpringGeneralizedForce to int/ext knee rotation with zero stiffness but some viscosity. Is this basically a damper then?

RE: osim file documentation
I noticed some difficulty as well when using xml_write in the xml_io_tools. The toolbox gets mixed up if it finds ::. Instead, I used xml_write and used the Xerces xml engine (you can specify this as a preference for your input).

RE: Evaluate Contact Forces and Indentations
The ForceAnalysis option will give you this information.

prescribed dof in forward dynamics
I have a knee model with contact. I would like to run a forward dynamic simulation by prescribed knee flexion and have the simulation predict the other degrees of freedom. How do I prescribe the motion of 1 dof in a forward dynamics simulation?
Thanks,

How can I add a damper to my model?

<t>I tried that syntax and it didn't work.
