Research of Multigid Algorithms for Three-dimensional Problems of Elliptic Equation with Discontinuous Coefficients

Abstract: The multigrid algorithm for elliptic equations on curvilinear grids have been considered. The finite volume method have been used. It is supposed, that coefficients of the equations are discontinuous. It leads to the necessity of using grids adaptive to the break lines. The method rate of convergence at various parameters have been illustrated.Note: Research direction:Mathematical modelling in actual problems of science and technic
