Is J. Blazek's 2d unstructed code capable of computing fluid mach > 10 ?
 
All the validation examples given is subsonic or transonic. He uses Roe flux, and a limiter(I forget which types limiter). I tried the naca0012, it is normal when machinf=1, but when i set machinf=2, the program fails to run.
Is Roe flux competent for supersonic flow theoretically? Or I need to change some other conditions to make it work?
