✦ Synopsis


In this paper we discuss a method of deriving artificial nonreflecting boundary conditions for systems of conservation laws. We focus on an application from solar physics. The governing equations are the equations of ideal compressible magnetohydrodynamics (MHD), which are solved in a gravitationally stratified atmosphere. We derive the necessary equations, discuss implementational aspects, and show the effectiveness and efficiency of our boundary conditions in test calculations.

This paper is concerned with transparent boundary conditions (TBCs) for wide angle "parabolic" equations (WAPEs) in the application to underwater acoustics (assuming cylindrical symmetry). Existing discretizations of these TBCs introduce slight numerical reflections at this artificial boundary and a
