Abstract

A flexible and accurate method for solving nonlinear, frequency-dependent radiative transfer problems by a Monte Carlo technique is developed. The method is based upon the concept of effective scattering, wherein a fraction of the radiative energy absorbed is instantaneously and isotropically reradiated in a manner analogous to a scattering process. The method appears to be unconditionally stable, conserves energy exactly, and is suitable for handling either transparent or optically thick media.
