Abstract:

The aim of the current article is to provide an alternative numerically method in solving elliptic problems. The method is called hierarchical smoothing of residues HSRM. It is based on iteratively smoothing of the residual on the same grid through a smoothing operator on the same grid this reduce the complexity compare to the multigrid method. The Fourier method has been used for the convergence analysis. Numerical tests done are very promising for its efficiency
