Hello,

I am a beginner in Comsol. I want to model ultrasound wave propagation in water. In my domain, I have a solid domain too and the whole computational domain is surrounded by air.

I want to know can I replace the air domain by a boundary condition? If yes, what kind of boundary condition should I use for the water-air and solid-air interface? sound hard boundary or soft boundary?

Thanks,
