Hi.

It looks intresting. There are many methods of computing external rays. The parmeter external rays are field lines of the potential . Does your method is the same ?

Which program are you referring to? The wave simulations are using discretization (finite differences), as described in the paper https://hplgit.github.io/fdm-book/doc/pub/wave/pdf/wave-4print.pdf There are other methods, for instance one can work in Fourier space. In that case, propagating the wave is trivial, but boundary conditions may be more tricky to handle.
