Abstract

In this paper we present new multigrid line smoothers for solving higher order discretizations of scalar convection-dominated problems directly. The behavior of the smoothers is analyzed with Fourier smoothing analysis. A parallel tri-line variant is presented and evaluated. The smoothers are applied to convection-diffusion problems, discretized with a limiter and systems of Navier-Stokes and Euler equations.
