A comparative study of limiting strategies in discontinuous Galerkin schemes for the M1 model of radiation transport

© 2018 Elsevier B.V. The M1 minimum entropy moment system is a system of hyperbolic balance laws that approximates the radiation transport equation, and has many desirable properties. Among them are symmetric hyperbolicity, entropy decay, moment realizability, and correct behavior in the diffusion and free-streaming limits. However, numerical difficulties arise when approximating the solution of the M1 model by high order numerical schemes; namely maintaining the realizability of the numerical solution and controlling spurious oscillations....
