Presure Field Not Converged in FSI using Ansys-CFX Coupling
 

Hi Every body

I'm simulating FSI case of interaction between an Airfoil(NACA0012) and air.

i first run steady state Fluid only simulation and after use it as initial condition for my FSI problem.
in FSI case i also use constant flow of 10[m/s] as in steady case, so i should see no change in pressure and velocity fields, but i see that from first time step although the velocity field keeps the same, but pressure field not solved good and in fact is Funny( i attached my pressure counter) !!:)

for inlet i set velocity(10[m/s]) and for outlet relative static pressure = 0

i have a C-mesh

i will thank a lot for Anybody helps me
