Asymptotic-preserving well-balanced schemes for 1D radiative transfer
Abstract:
We are concerned with efficient numerical simulation of the radiative
transfer equations. To this end, we follow the Well-Balanced approach's
canvas and reformulate the relaxation term as a nonconservative product
regularized by steady-state curves while keeping the velocity variable
continuous. These steady-state equations are of Fredholm type. The
resulting upwind schemes are proved to be stable under a reasonable
parabolic CFL condition of the type
among other desirable properties.
