Dear FOAM'ers,

Currently I'm working on my thesis and I'm struggling a bit with the exact solver to use. I want to model cavitation using different barotropic models. Also I'm only interested in a steady picture, transient effects are not relevant. The case that is used for validation are several headforms from the work of Rouse & McNown.

To my understanding the use of a barotropic model automatically implies that the solver should be fully compressible, correct? As I see it now I have two options:
- Make steady version of cavitatingFoam (is that even possible?) and fiddle with different compressibility models to obtain the desired barotropic behaviour
- Use rhoCentralFoam and find a way to insert a new barotropic model

Could you please advise me on these two solvers?
Any other suggestions are also very welcome, but be advised that I'm not interested in cavitation models that use a vapor transport equation, I want to hold on to a homogeneous mixture approach.
