A Robust High-order Approximation of the Gray Thermal Radiative Transfer Equations
Jean-Luc Guermond, Wyatt M. R. Smith, Eric J. Tovar
We present a high-order, positivity preserving, and asymptotic preserving approximation of the gray radiative transfer equations. The time and space approximation is done using a d…

Invariant-domain preserving IMEX schemes for the nonequilibrium Gray Radiation-Hydrodynamics equations Part I
Jean-Luc Guermond, Eric J. Tovar
In this work we introduce an implicit-explicit invariant-domain preserving approximation of the nonequilibrium gray radiation-hydrodynamics equations. A time and space approximatio…
