Hi, can someone please tell me if it is okay that in 2-WAY ANSYS FSI (System Coupling), each module says "not yet converged" but the overall status shows "converged"?

Hello Farah, 

"Not yet converged" here states that this specific Data Transfer has not yet converged for the current System Coupling step. This is either because the target RMS value has not been reached or the Minimum number of Coupling Iterations has not been reached.

 

The Participant Solution Status having converged means that each of these participants have successfully converged during this Coupling Iteration.

Here's some documentation that provides more details:
