High speed rotation analysis with friction is borderline impossible for a couple reasons. One, finite elements can't be rotated more than 2 or 3 degree per step. Two, the element faces for contact are constantly changing so the rotation should not produce translational motion of more than 1/2 element length per step. Even with small time steps convergence will constantly be slow making the run time almost unlimited. Technology Showcase Example 28 in the APDL doc. is a simpler analysis than yours, yet takes 24 hours to run. What is the object of the analysis? What do you want to find out? Â
