GeoAc software illustration

Propagation paths with amplitude.

GeoAc is a numerical package written in C++ which solves the equations governing acoustic propagation through the atmosphere in the geometric limit using a RK4 algorithm.

GeoAc contains multiple instances of said equation system and is able to model propagation in an azimuthal plane using the effective motionless medium approximation as well as in three dimensions using an inhomogeneous moving background medium.

The three dimensional propagation scheme include methods to model propagation in a Cartesian coordinate system as well as a spherical coordinate system which incorporates the curvature of the earth.
