CMC Changes in 1.8.1?

Post by Kathleen Reilly » Wed Apr 15, 2009 3:41 pm

I was wondering if there were any changes to the way the CMC tool works in version 1.8.1. When I constrain a particular muscle activation in 1.8.1, CMC doesn't seem to respond to the constraint at all. It responded well in 1.5. Any ideas?

Hi Kathleen
Could you tell me how do you constrain the muscle activation in a certain level?

Hi Ruiyi,

You can specify Control Constraints file in your setup file for CMC to set bounds on how the CMC algorithm activates muscles.

Please check the examples included with the OpenSim distribution along with the user guide chapter on CMC for details.
