Hello,

I wanted to create a one way FSI in System Coupling from transient structure to fluid. Bellow is a screenshot of my set up. I suppressed the data transfer force. 

When I do this, I can't input max/min interation steps in the solution control (see screenshot bellow).

When I unsupress the force data transfer inputting max/min iterations is possible. How can I run a one way fsi in system coupling and be able to input iterations?

I want to use system coupling and not workbench to not have to deal with workbench errors.

Thank you in advance!

Hello, 

since this is one-way coupling, you do not need Coupling Iterations to converge a Coupling Step. As long as your Transient Structural step is converged, the incremental displacements are passed onto Fluent and you can move on to the next Coupling Step.
