Acoustic source in a fluid - where to start

Post by jollyroger »

Im just learning Elmer and trying model a vibrating acoustic source under water. Ive got the elastic model working for the acoustic source (moving plate) but Im a bit stuck in how to couple this to a body of water.

Im using the Navier stokes equations for the water body, but dont seem to get a pressure wave propagating.

Are there any acoustic examples out there that demonstrate this simple case?
