Cavitation model
How to simulate Cavitation model in Flow 3D? Can you help me?

Do you need to model the actual bubbles forming and collapsing, or just find out where cavitation will occur? If you need to model the actual cavities (because they change the flow path around the cavitating object), then use the full cavitation model, and specify PCAV = cavitation pressure and CAVRT = characteristic cavity formation time = 0.001 second. The model will run very slowly. If you just want to know where cavitation will occur, either use the 'Cavitation Potential' model, or just look at pressure output around your objects of interest.

How about Cavitation potential value?
I have the value of Cavitation potential in my simulation but I do not understand about this value.

Cavitation Potential is a cellbycell value that is the timeintegral of the magnitude of the difference between local cellcentered pressure and userspecified cavitation pressure. It is the sum of that difference for all time steps where the local pressure is less than the cavitation pressure. Because the units are pressure x time (dt), they are the same as dynamic viscosity.
