Multigrid Methods for the Solution of the Compressible Navier-Stokes Equations,quations as well. Examples for multigrid applications in explicit and implicit Euler Solutions are given by Cima, Johnson [5], Ni [6], Jameson [7] and by Hemker[8], Mulder[9] and others. Navier-Stokes applications can be found e. g. in the paper of Shaw, Wesseling [10], Thomas et al [11] and Schröde

Multilevel Preconditioning Matrices and Multigrid V-Cycle Methods,iew this method in the framework of the classical multigrid method of V-cycle type. For this natural multigrid method it is enough to use the corresponding two-level ordering of the stiffness matrix at each discretization level. Then the smoothing procedure is naturally derived from the stiffness ma

Algebraic Multigrid Methods and the Schur Complement,In this paper we propose and discuss a general purely algebraic framework for multilevel iterative schemes for solving linear Systems where the role of the ‘coarse grid’ Operators is played by Schur complements.

Treatment of Singular Perturbation Problems with Multigrid Methods, linear problems were considered. An algorithm has been found heuristically for which the usual lower bound for the spectral radius of the iteration matrix of 1/2 does not hold. Artificial viscosity is used to obtain a stable discretisation. The algorithm is discussed and numerical results are presented.
