Hi, I'm trying to use rhoCentralFoam on the case aerofoilNACA0012 in order to compare the results with those obtained with sonicFoam.
Actually, I took the case from $FOAM_TUTORIALS/compressible/sonicFoam/RAS/aerofoilNACA0012. The application in ControlDict was rhoPimpleFoam. I changed it to sonicFoam. It worked.
I then changed to rhoCentralFoam, added what was asked in fvScheme and after a few iterations, I have a negative temperature.

As you could guess, I'm new to OpenFoam and I may not use the good way to work.
How can I use the case to compare both solver ?
It actually may not be exactly that case, I juste want a compressible turbulent case (the prism case gives me the same problem).
