Thank you, Rahul, for your valuable suggestions. I have tried both "under relaxation" and "stabilization" techniques. The simulation, however, is still unable to converge to any solution.

I would love to read "Best Practices for Coupled Fluid-Structure Interaction (FSI)", however, it seems I do not have access to them. Out of curiosity, is it possible to get them via email?
