Hi all.

I solve 2 way FSI analysis (Fluent-Transient Structural analysis in Workbench R14) with large deformations of fluid mesh. I did the tutorial for system coupling. I ran my analysis with hexahedral mesh, but with some limits caused by large deformations (high distortion - solution failed).

Please, does anyone have experience with a tetrahedral mesh in 2w FSI? I'm not able to run the analysis. Always with error:

+================================================= ===================+
| NOTICE |
| An exception has occurred and has been transmitted to the coupling |
| participants. These participants have been disconnected from the |
| coupling service. |
+================================================= ===================+



+================================================= ===================+
| System Coupling Exception |
+================================================= ===================+
| Origin : Fluid Flow (FLUENT) (Solution 1) |
| Error Code : 2 |
| Error Description : |
| Fluent encountered fatal error after sync point Solve |
+================================================= ===================+


Thank you.
Regards,
Katerina
