Synthetic acceleration of coarse-mesh S/sub n/ transport calculations
The lack of an effective method for accelerating the iterative evaluation of the scattering term has, to date, limited the usefulness of multidimensional nodal S/sub n/ schemes. Although the diffusion-synthetic method is potentially one of the most efficient acceleration techniques, the instability of this method for large mesh widths (when the diffusion equation is conventionally differenced) makes it necessary to apply specially-designed differencing techniques to the solution of the diffusion equation. In this summary, we develop a stable diffusion scheme for synthetic acceleration of nodal S/sub n/ calculations in multidimensional Cartesian geometries and show that the equations of this scheme can be solved in an efficient manner. 12 references.
