摘要: Abstract A grid refinement technique for high resolution magnetohydrodynamical flows is described. It based on the use of multiple nested grids having successively higher resolution. The numerical algorithm formulated in such a way that advection part hydrodynamical equations are solved conservative form whoel integration domain. In particular, divergence free constraint magnetic field, ▿ · B = 0 , fulfilled during simulation. Several tests presented demonstrating applicability code to many astrophysical problems including phenomena which steep gradients as shocks or contact discontinuities appear.
