Triangular and Alternately-Triangular Smoothers for Multigrid Methods
In article modification of a multigrid method of the solution of problems of processes heat and mass transfer are offered strongly nonsymmetrical systems of the linear algebraic equations received after difference of approximation of the equation of convection-diffusion with dominant convection are considered. Ways of a choice various smoothing from a class triangular and alternately-triangular skew-symmetric iterative methods are investigated. Results of the Fourier-analysis of the given modification of a multigrid method are presented.
