aerospike simulation at mach number 6 using Fluent 6.3
 
Dear All..
I am trying to do a hypersonic flow simulation over a spiked blunt body at mach 6 using fluent 6.3
In my case, I use first order upwind scheme and get a very well converged solution. however, when I switch to second
order upwind scheme, totally diverge
Any one has some suggestion to resolve this problem?
