Convergence problem in SUPERSONIC FLOW
 

Hi,

I am solving the flow in cavity for supersonic flows. I find the following problems: 1. The solution doesnot converge .(I gave a convergence criteria of 0.0001) 2. In case of shocks where should I use UNSTEADY computation and where should I use STEADY computation. 3. finally, What are the most imporatnt things to look into when using when simulating supersonic flow . THANKS A LOT SRIDHAr
