Hello,everyone!
Recently, I have a strange problem in supersonic NS simulation with SU2. It is a 2Ma 2D wedge. Turbulence model is SA. I set farfield, NS_wall, outlet boundary condition. The pressure contour of result shows strange at the two junctions place --farfield and NS_wall, outlet and NS_wall. Below is my grid and SU2 configuration file, contour of the result. Appreciate any reply! |

It looks like you are simulating a bump instead of a wedge; you might want to recheck your boundary conditions...

The boundary condition is set as: the lower boundary--wall; the upper and left boundary--farfield; the right boundary--outlet.

Exactly... shouldn't you use a symmetry/slipwall if you want to simulate a wedge instead of a bump (there's a difference between the two).
