Hi Federico, thanks for the response. Does the link work with copy and paste? It contains the .sat files of 2 simulation models. It's supposed to be a simple model of a speaker for developing an impedance measuring device. The actual model is more complex. I've gradually reduced it to pinpoint where the error might be. I'm concerned that the boundary condition isn't being applied correctly. To check this, I'm setting a surface velocity of one meter per second on the membrane and examining the simulated velocity output at the boundary surface. This works satisfactorily for the LS file but not for the LS2 file. I hope the issue is clearer now, but feel free to ask further questions if needed. Regards, Lars
