I am interested in investigating acoustic propagation with the LBM. I have been trying to recreate some simple examples from [1] in FluidX3D using the liquid metal on a speaker example as a starting point. The difference is that instead of varying the velocity at a point I am trying to vary the density to create an acoustic source; I have the following main_setup
The issue is that I observe the density varying at the source position but not anywhere else in the field. Is what I am trying to do possible in FluidX3D/what do I need to do to make it work?
Many thanks,
Fin.
