beear is on a distinguished road

I have a problem with a 2 two ways FSI, I'm tryin' to simulate a valve at the output of a pump (it's like a reed valve) with transient structural and Fluent. I've done both setup, and when I launch the solver, the programm stop before any iteration with the following error message:

"(DP 0) System coupling run completed with errors. Fluide (Solution 4) reported: Fluent encountered fatal error after sync point Analysis Initialization : received a fatal signal (Segmentation fault)."

In the solution information of fluid part, it's written :
"Error: No journal response to dialog box message:'Warning: Invalid initial data. Probably available initial data file is not compatible to Fluent's current mesh. Using basic initialization based on settings...~%"

I precise that I don't have any UDF. Can somebody help me fix this? I try to launch them separely and they both work alone, but not coupled...
