I could apply 2 of your suggestions to my numerical model:

1- I increased the maximum number of coupling iterations per step.

2- I increased the max. iterations/time step in Fluent.

However, my solution could not converge yet.

Can you please tell me how I can apply your first suggestion to my model?

"Have you tried using monitors to identify the instability? You can monitor pressure/force convergence for FSI surfaces within each time step."

I did monitor for example area-avereaged pressure in Fluent (not in my FSI simulations). But how I can do it while I am running the FSI simulations (the Fluent window is closed).
