Convective Wave Equation

Hi, do you think it is easy to extend the present bempp to consider the convective flow effect? It means that the convective wave equation in the frequency domain needs to be solved. It will be much more meaningful for acoustic application like aircraft or train noise evaluation in manuvering status.

To my knowledge this is a time-dependent problem. You are looking at a very different set of problems here, for which Bempp was not designed.

Hi, Dr. Timo, thanks for your reply. It is a time-dependent problem, but the governing equation can be transformed into the original Helmholtz equation in bempp using Plandtl-Glauert transformation. I am still learning the bempp code structure, and it seems possible to do that improvement. But it definitely needs much work to do for re-deriving the BIE.
