      Transient analysis fixed top roller. I move the bottom roller z direction 1mm. I have defined friction between the balls and the inner surfaces of the cylinder. However, it keeps crashing, can you help with this?

      It looks like you trying to simulate a roller ball bearing. What questions about a ball bearing do you have that you need to answer? Most questions can be answered be reference to a ball bearing manufacturer's web page.
      In a prior discussion https://forum.ansys.com/discussion/36273/simultaneous-rotational-and-translational-motion-of-the-cylinder#latest you were not successful getting one ball to make frictional contact with one block. I suggest you get that model working before you move on to a more difficult model.
