A Program based on the Wide-Angle Mode Parabolic Equations Method for Computing Acoustic Fields in Shallow Water

A description of a program for computation of acoustic fields in 3D shallow-water waveguides of arbitrary form is presented. This program is a C++ implementation of a numerical solver of wide-angle mode parabolic equations. The user can specify sound speed distribution, bottom relief, and the structure of bottom layers via configuration files when performing acoustic field simulation. The output of the program consists of one or several horizontal cut planes of the acoustic pressure field at specified depths. One of the main advantages of the implemented method is its high computational efficiency. The developed program is open-source and available online. It can be of interest for specialists in different areas of ocean acoustics who perform the modeling of sound propagation in course of the solution of various practical problems.
