Default When to use steady and unsteady calculations
Posts: n/a
Hi there,

I am a new user in FLUENT and generally CFD. I have the following question:

May I know how I can decide if the flow problem I have requires me to use Steady state or unsteady state calculations. On what basis should I decide the above?

Thanks in advance!
