ramin Guest Posts: n/a	Hi I am trying to simulate 2-d unsteady flow over a NACA0015 airfil.The simulation should be able to show the vortex shredding too.It's an incompressible flow (M=0.18),15 angle of attack,Hi Re number,I am using my finest grid, C-type,with a value of (y+)=1.Op. Conditions, Pressure=0.I tried several turbolent model but i think LES or DES is the best.inlet BL is inlet velocity and outlet BL is outflow.Do you think I've chosed the right model and the boundary conditions and etc.?Am I doing something wrong? is there any suggestions about this simulate? any suggestions would be very very welcome. thanks
