Non-Equilibrium Radiation for the HULL Code

Abstract

A treatment of flux-limited radiation diffusion is incorporated into the HULL code. The differential equations in the non-equilibrium radiation diffusion model are discussed, as well as the flux limiters. The difference equations used are also derived. The code has been exercised on several test problems and results from two of these test problems are reported.
