Please login with a confirmed email address before reporting spam

Hello all, i want to simulate a 3D impedance tube consisting of MPP having conical holes combined with porous absorber. i have given PML and background pressure field as seperate domains. So how to get the combined sound absorption coefficient of the combination. what additional settings are required?
