Hello all.. I need to study the effect of dynamic fluid on acoustic wave propagation using Comsol 5.4. I don't know exactly which interface of the software to be used. Can someone please help me with this problem. If possible please attach the related file too. Thank you.

In the model wizard, choose one of the physics interfaces under Acoustics->Aeroacoustics.

Thank you sir. But I already tried modelling with all the intefaces provided in Aeroacoustics branch. I'm not able to provide an external acoustic source in any of those interfaces. I need to provide a monopole point source in a dynamic fluid domain(water) and find the variation in acoustic pressure due to the effect of flow. I would really appreciate the help. I've been stuck with this problem over a month.

Thank you.
