While doing some simulations with the version 6.2.0, I found a strange behaviour on the pressure field.
The test case is a naca0012 at AoA=0°, M=0.7, Re=9e6.
When running with SST turbulence model, the pressure field in the "boundary layer region" is not constant. Using SA turbulence model, this behaviour is not shown. It looks like the tubulent kinetic energy field affect the computation of pressure field, leading to a non zero gradient pressure at wall, as shown in the attached figures:

In the figures it can be seen a comparison between the in-house solver of the Italian Aerospace Research Center (CIRA), where SST model is implemented, and SU2 using both available turbulence models, SST and SA. The isolines represent the pressure field and the contour is the TKE field obtained with SU2 with SST. In particular, solid red line is CIRA solver, the solid black line is SU2-SST, and dashed black line is SU2-SA.

Near the LE where TKE is 0, the isolines are similar and 0 pressure gradient at the wall is obtained with both turbulence models. When TKE starts to grow, the pressure computed with SU2-SST shows a non constant behaviour and at the wall has non 0 gradient. Furthermore, in the wake region the defect is more evident.

Has anyone found previously this behaviour? Could it depend on the set up that I have used?

I attach the grid and configurations files.

Thanks in advance.
