alireza_b is an unknown quantity at this point
Dear Friends
I want to simulate oscillatory airfoil at Re=36000 based on paper of Kontis (Synthetic jet control effectiveness on stationary and pitching airfoil). In this paper, they used 0.0001 for Dt (with Fluent). but when I used this time step, my solution is wrong. while Dt=0.001 I get good solutiom but when dt=0.0001 I have wrong solution.

anybody knows why?
my boundary condition is velocity inlet and pressure outlet.

Thanks
