Running nacaAirfoil tutorial with sonicFoam
 

Hi,
as stated in title,running such tutorial goes nowhere,that is,no convergence at all,unstable coefficients ...I wonder if there is any setting-up problem or so.
I have also tried a naca study at high subsonic regime (about M=0.6) but drives to the same conclusions (also using sonicFoam).Is there any better solver to use for these range?
I would appreciate any lifeboat in this turbulent sea;)
