Hello All.
In Acoustics, impedance boundary conditions are defined as Robin conditions (sum of normal derivative of the complex acoustic pressure plus the pressure itself); the righthand side is a function g defined on the boundary. Am I correct to say that the function g describes possible sources of acoustic radiation, hence it is 0 for scattering problems and nonzero for radiation problems ? Thank you for your help to understand! David.
