Locally conservative redistribution limiting and applications to the approximation of conservation equations, Part II
Jean-Luc Guermond
A non-intrusive, discretization and PDE agnostic limiting technique is introduced. The method is conservative and can be applied to high-order approximations including spectral met…

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…

Preconditioning of the generalized Stokes problem arising from the approximation of the time-dependent Navier-Stokes equations
Melvin Creff, Jean-Luc Guermond
The paper compares standard iterative methods for solving the generalized Stokes problem arising from the time and space approximation of the time-dependent incompressible Navier-S…
