The Su-Olson problem consists of a one-dimensional, half-space, non-equilibrium
Marshak wave. The radiative transfer model is a one-group
diffusion approximation with a finite radiation source boundary
condition, where the radiative and material fields are out of
equilibrium. As the energy density of the radiation field increases,
energy is transfered to the material.
Su & Olson (1996)
found a solution, to quadrature, for the distribution of radiative energy and
material temperature as a function of spacetime. This solution
is useful for verifying time-dependent radiation diffusion codes.
This article,
this article,
and this article,
discuss analytic and numerical solutions for the Su-Olson problem.
The tools in su_olson.tbz reproduce the tables in the Su & Olson article and provide solutions as a function of time and position.
