About Engine Connecting Rod Example in Stress and Local Equilibrium Course

Trying to replicate the Engine Connecting Rod example I encounted a number of warnings and the error reading as 'Accelerations are exceeding internal limit. Solution will not proceed'. Could anyone please advise me how I should tweak the solution settings to solve the model?

    Use a much smaller Initial and Minimum Time Step under the Analysis Settings. By a factor of 10 or 100.

    Thanks for your reply. I decreased the Minimum Time Step by 100. However, I still can't solve the model. The Driver Joint-Rotational velocity (Load Step 0) condition is violated in direction RZ by 0 warning persists, as per the following screenshot.

    Maybe the error relating to invalid joint properties does not allow me to solve the problem. But I can't figure out what's wrong with them. The Redundancy analysis says that the number of DOF is 1, as per the following screenshot.
