Hi guys,

I simulate cavitation in a centrifugal pump. At the exit of the pump i have defined pressure-outlet. (Is it the only available option for exit for cavitation simulation?) At the inlet i have defined velocity-inlet. I have set the operating pressure 101325 Pa. I cant understand the significance of the reference pressure location!! Where will i define it??
The point that i defined it, has gauge static pressure 0.

Thanks a lot!!
