An implementation of the multigrid method on conformal block-structured grids is proposed. The algorithm is intended to solve a boundary-value problem for elliptic PDEs. Each block is discretized using a structured hexahedron grid.The set of multilev

A previously formulated new approach to the consideration of systems of quasilinear hyperbolic equations on the basis of variational principles is described in more detail in the case of special systems of three equations. It is shown that each field

Two schemes for solving initial–boundary value problems for three-dimensional parabolic equations are studied. One is implicit and is solved using the multigrid method, while the other is explicit iterative and is based on optimal properties of the

We propose an efficient multigrid algorithm for solving anisotropic elliptic difference equations. The algorithm is based on using Chebyshev’s explicit iterations at smoothing stages and in solving coarse-grid equations. We have developed a procedu
