Diffusive Corrections to Pn Approximations
Matthias Schaefer, Martin Frank, C. David Levermore
In this paper, we investigate moment methods from a general point of view using an operator notation. This theoretical approach lets us explore the moment closure problem in more d…

Adaptive Finite Element Simulation of the Time-dependent Simplified PN Equations
Martin Frank, Jens Lang, Matthias Schaefer
The steady-state simplified approximation to the radiative transport equation has been successfully applied to many problems involving radiation. Recently, time-dependent sim…
