Hi,

I have only a very general answer: If you have the set of PDEs and boundary conditions that describe the phenomenon you can implement them using the PDE interface. I doubt that cavitation is covered by one of the ready-cooked application modules.

Cheers
Edgar

I'm sure it's possible, but you will have to implement it yourself from the governing equations. Acoustic cavitation, especially transient cavitation, is highly non-linear and it would be interesting to see some attempt to model it using COMSOL.

If you can benchmark a COMSOL model of a simple cavitating scenario with a known result, you should post it to the model exchange. I would be interested in it.
