I want to ask about acoustic analogy models avaliable in COMSOL. Is FFWH acoustic analogy model is avaliable in COMSOL or not? I have search for the avalaible online materials but i have not found any information

Dear Zein

There are currently no acoustic analogy models implemented in comsol. We have convected acoustic equation formulations like the linearized Euler or linearized Navier-Stokes but no models to compute the flow induced noise source terms.

Best regards
