Emptying a tank simulation through Fluent
 

Dear All friend,

I have seen two kinds of tutorials for emptying (draining) tank simulation. One is considering pressure outlet at the reservoir end and one with pressure inlet. Which condition works best? I have applied both, but the tank water is not moving a mili meter even. For pressure outlet at the drain side, the backflow volume fraction is 1. In case, if I apply pressure inlet, what about supersonic/initial gauge pressure? by default, everything is zero at the pressure inlet (as per tutorial) .Operating pressure is 101325Pa

Regards,
