tested: incomplete Cholesky and multigrid. Numerical experiments indicate that these preconditioners are efficient at …

This paper deals with the aim of coupling multigrid generation of boundary-fitted grids with an effective domain … elliptic systems and the application of multigrid cycling. We assume the Laplacians of the curvilinear coordinates to be equal … block iterations along with multigrid cycling in each block. We present computed multiblock grids by Figures and evaluation …

algorithm based on policies iterations and multigrid methods. Numerical results are displayed for n = 1 and n = 2. …
