Error access violation
 

I modelized a turbine with Gambit,then I export it in Fluent. I set up the solver and the Boundaries conditions (Moving wall, Pressure inlet and Pressure outlet). When I want to initialize the solution Fluent write :

Error : Fluent receive a fatal signal (ACCESS_VIOLATION) 1. Note exact events leading to error. 2. Save case/data 3. Exit the program and restart to continue. 4. Report error to your distributor Error Objet: ()

Can you help please.

Thank you in advance
