Reply To: Aeroacoustic simulation in OpenLB


Dear Mathias,

Thank you for quick reply.

I am not sure if I understand your answer. I have some experience with N-S (RANS/URANS) solvers, but the LBM method is completely new for me.

I thought that when we consider the aeroacoustic simulation in LBM method, we solve both the flow and acoustic propagation (direct CAA approach). The question is how it is possible if you make an assumption of incompressible flow? Or maybe I miss something?

Specifically, I am interested in predicting noise generated by a quad-copter.
