Hi,

I am working on a project based on the flutter condition of a wing. To do it, I am trying to do a 2 way FSI study with ANSYS-FLUENT. I have already built the wing and done the modal study and the results are quite good. However, I am facing some problems. In my case, the study is at Mach 0.9. The information I have found suggest to modify the static pressure and realize in which case the damping coefficient is zero.

-Which solver is the most accurate one for a transonic flow?
-In fluent, I have defined a velocity inlet and pressure outlet, but I dont know if this is correct in this situation.
-In which part of the fluent configuration should I put the velocity?
-How can I display the damping coefficient in ANSYS_FLUENT, so I can see the flutter condition?

Thank you in advance.
