Hi, nevermind my last response. Reran the sims and wrapping issue was sort of solved two ways: (1) as you suggested, switching to a via point, and (2) moving the torus. Although the via point solved the muscle jumping, I noticed the muscle moment arms were zero for several of the instances where it ...

Hi, thanks for the suggestion. When (a) removing the torus wrapping or (b) removing the torus wrapping and adding a via point at or near the torus centroid, the motion is smooth but the muscle seems to duplicate itself (ie. there are two lines of action from the insertion points). Please see attache...

I've tried midpoint & axial wrapping methods as advised by the docs, and I understand that muscle wrapping (particularly around ellipsoids) is an ...
