title = "Negative flux fixups in discontinous finite element SN transport",
abstract = "We introduce a conservative fixup strategy to remedy negative fluxes within a linear discontinuous spatially discretized radiation transport solver. The strategy is similar in principle to the classical set-to-zero fixup used with diamond difference schemes. We also discuss difficulties in creating an effective solver for such an approach and propose a hybrid source iteration/Krylov solver. Numerical results are presented for 2-D test cases.",
