Hello,

I) I would like to know how i can choose Either implicit unsteady or explicit unsteady while working in coupled solver.Is there any condition to choose?

II) When i sloved by unsteady state condition it take long time to slove simualtion. how i would minimize the iterating time.
and also what is relationship between CFL,Courant number,time step,No of inner iteration and Maximum physical time.will this five parameter will help to min time?

Plz any one can reply for this.

Rergards,
