Hi,

Thanks, I agree that your suggestion works in removing reflections at the open boundary. However, what is the impact of employing such a method in the study of acoustics where the inlet will be replaced by a time-dependent oscillating input?

I suppose the sound waves introduced into the system will reflect off the outlet regardless if the inlet is set to be a slowly increasing one?
