Hi Elmer Community, I have a question regarding interior boundary conditions in the Helmholtz solver module. I have tried to model interior, sound-reflecting walls by imposing a wave flux of zero on the corresponding surfaces; however, it seems that Elmer only sets the wave flux on one side of the c...

Hi, I am currently working on a similar problem. I am trying to determine the eigenfrequencies of an air filled, two-dimensional channel with two rigid walls and two open ends. The open ends of the channel are modelled with a pressure wave boundary condition. I also work with frequency sweeps to det...
