Abstract
The authors present a multigrid method for solving the one-dimensional (1-D) slab-geometry S{sub N} equations with isotropic scattering and no absorption. This scheme is highly compatible with massively parallel computer architectures and represents a first step toward similar multigrid methods for the S{sub N} equations in curvilinear and multidimensional geometries. Extensive theoretical analyses are given for the scheme which indicate that it is extremely efficient. In fact, the method is so efficient that it very nearly represents an exact solution technique. Results from calculations are presented which validate the theoretical results.
