Airfoil Validation
 
I am simulating incompressible flow over NACA0012 airfoil using CFX. i used upwind scheme, SST turbulence model , Computational results are well matching with experimental results at low angles but i am not getting stall for any higher angles. can anybody please help me in this reg..

Thanks in Advance

Make sure that your domain is big enough. Can you post an image of the domain with the airfoil? What kind of boundary conditions did you use?
