We have an exciting announcement about badges coming in May 2025. Until then, we will temporarily stop issuing new badges for course completions and certifications. However, all completions will be recorded and fulfilled after May 2025.

Hello Davide,

If you're encountering an issue where the system coupling has not yet converged, it could be due to a variety of factors.

One common cause is that the solution is not yet fully converged. Check this link : Error: update failed for the solution component in system coupling. The coupled update for system fluid flow (fluent) threw an exception. Update solution failed - Ansys Knowledge.

Another potential issue could be related to the stability of your FSI or 6DOF case. This link : How can I converge an unstable FSI or 6DOF case in Fluent - Ansys Knowledge, provides a comprehensive guide on how to use Fluent's Solution Stabilization for an FSI case or a 6DOF case. It includes information on how to identify instability, how to use solution stabilization, and how to adjust settings for optimal results.

I hope these guidelines will help you with your project.

Thank you,

Tasos
