Underwater Arcs: reflecting waves

So, as a sanity check I decided to simulate focusing the wave from an underwater arc. The simulation setup is very simplified-a cell is chosen to have 10X the pressure of the surrounding cells in a parabolic geometry. I’ve tried modeling this with cavitatingFoam and sonicFoam. sonicFoam only models the equation of state for gases which is not ideal.

With cavityFoam

And it looks like this will not work because of the different times to the focal point for different paths. This would not be a problem with an acoustic lens, so I will be working more on that instead.
