pressure waves in a liquid

Post by jollyroger »

Does anyone know if the navier stokes time domain model can successfully model pressure waves (sound) in a liquid. I have a moving plate in a liquid and expect to see sound waves being produced by it. It works if i make the fluid air, but not if i make it water. I think i dont understand how to tell elmer that the water is actually compressible.
