- Abstract
- A series of three recently-published papers described applications of the Boundary Integral Equation Method (BIEM) to the calculation of acoustic fields in waveguides with two-dimensional boundary deformations. This report is the documentation for a set of computer codes which implements the concepts described in these papers. These codes can model acoustic fields generated by line- and point- sources in waveguides with two-dimensional boundary variations. They support stratified sound speed and attenuation profiles, and fairly general compact deformation on one of the waveguide boundaries. A unified summary of the theory is followed by a detailed description of the techniques used for its implementation in the numerical codes. The final part of the work describes the codes and their use.
