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

I think one could do an inverse dynamic analysis through the OpenSim's ID Tool using the Moco Solution. I have not tried it though.

Hi Ross Miller,
I am also struggling with it. My work flow is quite similar to yours. Its hard to get good convergence. I stopped at some point . I may have to start trying again.

Oh. Thanks. I was also struck with the same issue. Now got the answer.

Hi Ross Miller, I believe that Moco uses same definition as that of opensim. In opensim joint reaction includes muscle forces and resultant from inverse dynamics. The reaction force Ri is calculated from the below free body diagram. Reaction.png The following links may be helpful. https://simtk-conf...

Hi Ross Miller,
Thanks for sharing the updated version. I am curious to know how you formulate the predictive simulations and that will be helpful.

It is great to see this result. Thanks for sharing it here Ross Miller.

Hi Carlos, Probably there is some default value of slow twitch ratio. However the third optional argument for the addMuscle method is slow twitch ratio. You can pass the desired value of slow twitch ratio as the third argument. One can use methodsview() in Matlab to see all the available arguments. ...

Yes Nick. Based on Brian Umberger's code. Thanks. I am using these settings for implicit muscle dynamics. I would like to confirm whether the output includes basal heat rate. I could not find a method for setting the basal heat rate on. However getBasalCoefficient method gave a value of 1.2. I also ...

Oh. Thanks Ross Miller for the explanation. That was really helpful.
