I am trying to use the acoustics module with the perfectly matched layers to absorb any signal interacting with the boundary. What I want is analagous to plane wave radiation, but I want to use the perfectly matched layers since I need to later impliment the poroelastic waves module. It seems like the perfectly matched layers is being overidden by sound hard wall boundary, and I'm not sure how to change that. Any help would be greatly apprciated.
