Hello all,

I'm sorry for my basic question...
I'm running transient 2 way FSI. I've set maximum number of coupling iterations to 10. For some timesteps the maximum number of coupling iterations is reached.
What does it mean? And what do you suggest to correct (finer mesh, smaller timestep?).

Thanks,
Pavel

It means the quantities you are passing across the interface (force/displacement or temperature/heat flux) have not converged within that timestep. I suggest you add monitor points to track those quantities and use "monitor coefficient loop convergence" so you can see how those quantities change within a timestep, then you can decide what to do next.
