Hei Baris It's not completely correct for interPhaseChangeFoam. Clearly for momentum equation it should not make a difference but since you want to resolve cavitation it is important that you...

Hi Baris When you run incompressible calculations the only effect on the flow due to pressure is based on the local pressure difference. So for example when you have a simple pipe case with one in...

Hi Zarox I guess the alphaNuc() is just to be able to start cavitation. When everything is water at the beginning you will always have a multiplication by zero (from alpha_vapor) even when p <...
