BERIM3 by Stephen Kirkup

The model that underlies the BERIM method models the acoustic field in a cavity with one opening. A recent paper describing the method in more detail and demonstrating its application to the acoustic field produced by a horn loudspeaker is given in the following link.

Computing the Acoustic Field of a Radiating Cavity by the Boundary Element -Rayleigh Integral Method (BERIM) with application to a Horn Loudspeaker by Stephen Kirkup* and Ambrose Thompson

The Fortran (77) subroutine BERIM3 implements the Boundary Element - Rayleigh Integral for general 3D problems: BERIM3 delivers a computational solution to the acoustic field produced by an open cavity.

The BERIM3 package is free for evaluation purposes and can be dowloaded free by members of the BEM-OS Group.
