i have been tryed to calculate the combustion noise by hybrid method ,the first step is to get instantaneous fluid data by Large eddy simulation on commerial software-Fluent. and the second step is that constructing the source of combustion noise from the LES data, and slove acoustic perturbation equation to simulate far-field sound pressure level wave propagate equation propwhich is demonstrated in many papers. Now, i plan to implement the second step by COMSOL
but the problem i encounter recently is which Physics interface i should choose to simulate frequency-domain Sound field characteristics based on the time-domain fluid data that i get from LES. and i don't know how to make use of the data after interpolating it into COMSOL. I am a new hand, can you give me some advice?
