Modeling external supersonic flow
 
Hi Everybody, I'm an almost new Fluent user. I'm trying to model an external air flow on a Martian lander. I haven't any trouble for Mach<1, using k-epsilon turbulence model, but for Mach>1.5 it's still quite good for first order convergence, then it's deverge as I upgrade to second order scheme. Does somebody have any advice?
