Getting "resultant knee force" from a state trajectory?

OpenSim Moco is a software toolkit to solve optimal control problems with musculoskeletal models defined in OpenSim using the direct collocation method.

 So by that terminology, you're saying that OpenSim's JointReactionAnalysis reports the "total reaction force", and that you're looking for the "partial reaction force"?

Yes, that's what I'm looking for (still looking!)

A work around may be to use only the motion trajectory from Moco solution and remove all the muscles and then call calcReactionOnChildExpressedInGround?

That's a good idea, thanks Karthick!
