Hi, I would like to know which optimizer is used when solving inverse kinematics in OpenSim 3.3. I found this post on the forum but I would like to make sure it is still up to date. "In OpenSim/Simbody the inverse kinematics solver uses different optimization algorithms depending on the problem. If ...

I have another question related to the low pass filter used in the InverseDynamicsTool. If I am right, the filter is a dual pass 3rd order filter. Is it thus right to say that, due to the dual pass, the effective cutoff frequency is lower than the selected cutoff frequency? This follows what is disc...
