This was discovered on modified versions of the Rajagopal Full Body model available on the OpenSim website. However, I believe I have recreated the issue starting with the f...

I'm not sure I saw a resolution to this problem in this chain, but I am having the same issue in an analysis plugin. I tried adding the call to computeStateVariableDerivatives(s), but it didn't make any difference. I am actually working on an on orbit exercise simulation for NASA, so I have set my g...
