Convergence estimates of the iterative algorithm for numerical solution of three-dimensional nonstationary problems of magnetic hydrodynamics

In this paper, we investigate the convergence of the applied to the completely conservative difference schemes (CCDS) 3-D magnetic hydrodynamics (MHD) methods of the combined and separated solution of groups of difference equations broken down by physical processes (the methods of splitting into processes). The area of applicability of these methods is shown. The validity of the estimates obtained is confirmed by numerical calculations.
