Onera M6 Validation
I am trying to use CFX to simulate the Onera M6 wind tunnel results at M-0.8395 and 3.06 degrees. The pressure distribution on the upper surface does not follow the wind tunnel data, particularly in the region of the shock wave. Has anyone done this simulation who can advise me of where I am going wrong?

Have you covered the basics? http://www.cfd-online.com/Wiki/Ansys..._inaccurate.3F

I've seen some pretty good results produced with CFX when modeling shock waves. Cover everything in the page Glenn posted. For starters, I'd ensure your y+ values are smaller than 1 to properly capture the viscous sublayer of the boundary layer. I'd also ensure the grid was refined in the shock region to capture any shock-induced separation.
