Error in Two-Way FSI simulation – system coupling
-

Hi, I'm following online tutorials to simulate a Two-Way FSI but when I get to system coupuling I allways get the same errors. There is a photo of the error messages and the solution infformation of the system coupling.

Hi,
From error message in system coupling logs, it is observed that issue is with Fluent setup. Please have a look at the Fluent Transcript file (.trn) to identify the cause of the issue and make necessary changes in Fluent setup.
I recommend going over this tutorial in the Ansys documentation that shows a 2-way FSI simulation with Fluent and Mechanical to understand the system coupling workflow. https://ansyshelp.ansys.com/account/secured?returnurl=/Views/Secured/corp/v221/en/sysc_tut/sysc_tut_reedvalve_fluent.html
