Eigenray tracing, however, is a boundary-value problem, rather than an initial-value problem. The boundary conditions are two endpoint locations, and the ray trajectory satisfies Fermat's principle of least traveltime. In this study, we apply the non-linear Finite Element Analysis to …

The Eigenray Acoustic Ray Tracing Code This is a page to download the source code for the "eigenray" ray propagation code for calculating the basic properties of rays over long ranges in deep water. Other hints for using this code and benchmarks can also be found here. Codes for Acoustic Propagation RAM in Fortran 95.

Eigenray method: Caustic identification Igor Ravve* and Zvi Koren, Emerson Summary At the last SEG meeting we presented the Eigenray method for finding stationary traveltime ray trajectories in 3D smooth heterogeneous anisotropic media, by applying a non-linear finite element scheme. We applied the Newton
