Hi all,

I'd like to try and model an air bubble (not a spherical one but a shape I will construct) surrounded by water, and in the air bubble I shall introduce a sound source.

I'd like to construct slice plots of the acoustic pressure distribution and absolute value of SPL both inside the bubble and in the surrounding water.

I'm unsure of which Physics modules to use and also how to couple the air bubble boundaries to the surrounding water.

In addition the ability to add a solid structure (fixed) on one side of the bubble (probably just sound hard boundaries between the air and solid) would be very beneficial.

Is this even possible? Any help or advice would be great.

Thanks

David
