upwind scheme
 
Hi all,

I am runing the symmetric and upwind TVD schemes at Mach < 3. In papers I've read(Yee, Harten), the Mach number can be hypersonic. However my code keeps blowing up at Ma > 5. The numerical method is the same for high and low Mach flows so I am unsure as to why it doesn't work. Is it to do with CFL?

find Quirk's article "Debate on great Riemann solver..." he wrote about "carbuncle phenomina" for M>6
