Hi,

I have been trying to run a hypersonic double cone problem with turbulence modelling. Using komega-sst, the omega diverged after 3-4 time steps. I changed to another model and the same thing happens. So I tried to run my case using my previous laminar solution, which completed w/p problem.

To reach steady state, I ran until t=0.005 in the laminar case. So I tried to use the laminar solution at t=0.0002 to start my turbulent case, and let it run till 0.005.

Is this a reasonable or correct way to simulate a turbulent case?

Another online study suggested running at a low Re 1st, then increasing the Re to the actual one as time proceeds. Is that ok too?

Thanks.
