Abstract
In this paper we present new multigrid line smoothers for the solution of higher order discretizations of convection-dominated problems dire ctly. The behavior of the smoothers is analyzed theoretically with Fou rier smoothing and two-grid analysis. A parallel tri-line variant is p resented and evaluated. The smoothers are applied to scalar convection -diffusion problems, discretized with limiters and systems of incompre ssible Navier-Stokes and Euler equations. (C) 1998 Academic Press.
