Hi all, I have a rather trivial issue I am trying to solve, but it seems like there isn't anything available online that I can find to help me. For this question, imagine I have a 2D annulus with a fixed inner ring and frictionless outer ring. I apply a moment to the outer ring and create distortion in the annulus. What I want to find is the rotation of any element on the outer ring with respect to the centre of the annulus or any node on the fixed ring in the centre. Is this possible to do in WorkBench? As my only idea was to possible manually ID the nodes and then output the positions over time, but I'm not too sure how to do this as yet. Any help would be appreciated!
