Hi Ali, Thanks for your message. It seems you are aiming to compare the muscle-generated joint moments + your added torque-actuator-generated moments to the inverse dynamics moments for the same motion. I did something similar for a previous project. There are some scripts here that might be a good ...

I can chip in a little bit here. Our lab published a lower limb OpenSim model a couple years ago. For that model, tendon slack lengths were set using the same ideas as described in the Manal and Buchanan paper you referenced. (We posed our OpenSim model in the same position as the cadavers from the ...

Hi Arash, Control constraints are not necessary to run CMC. Sometimes, it might be helpful to include control constraints to specify when certain muscles are on/off (e.g., constrain the plantarflexors to be off in mid-swing in walking) to help shape the feasible solution space, and this can be done ...

Hi Miriam, What quantities are you aiming to compute using your forward dynamics solutions? This may determine what tool is best suited for your application. The RRA tool essentially runs a closed-loop tracking forward simulation that roughly tracks desired kinematics. Running an open-loop forward s...

Hi Marco, I've gotten this error before too. Before you compile Simbody and OpenSim, you need to explicitly specify in CMake whether you want to build for 32-bit or 64-bit. Otherwise, one of them defaults to 32-bit and the other to 64-bit which is why the libraries are not compatible. (I forget whic...
