Thanks for your reply.

Compared to the previous simulation, I decreased the time step size from 0.005[s] to 0.0017[s], and URF from 1 to 0.5. Again, the solver failed to converge, surprisingly aborted even sooner than the previous model (with larger time step size and URF=1).




I can successfully run the Structural model and the Fluent one separately. However, my problem for almost one year is when I am coupling them to run the FSI simulation (in fact, I have already applied many different suggestions to my problem).

By any chance, do you think we can have a meeting to better study the issue? I can involve my advisory team in further contacts and communications. We are located at Marche Polytechnic University in Italy. Please let me know.
