Basic Question
 

Hi..I am doing simulation for De Laval nozzle. My inlet operating condition is 2MPa & outlet pr is 0.1Mpa and I want to use k epsilon model and steady state. I hav one simple question..do i hav to giv op condition directly this condition or i hav to go step by step. Start with low pr at inlet n outlet and then go on increasing it.

Can anybody throw some light on this. Thanks
