Higher-Order Discontinuous Galerkin Splitting Schemes for Fluids with Variable Viscosity

Richard Schussnig, Niklas Fehn, Douglas Ramalho Queiroz Pacheco +1

This article investigates matrix-free higher-order discontinuous Galerkin discretizations of the Navier--Stokes equations for incompressible flows with variable viscosity. The visc…
