3D numerical simulation of MHD flows in semidetached binary systems

3D numerical code for simulation of MHD flows in semidetached binary systems is developed. The code is based on finite-difference Godunov-type scheme for equations of magnetohydrodynamics in non-stationary curvilinear coordinates. The scheme has high resolution in regions of smoothness. The own magnetic field of accretor is considered as a dipole. To minimize errors for operations with large float numbers the only magnetic field induced by currents in accretion disk and circumbinary envelope is calculated in the scheme. Any demonstrative results of numerical simulation of mass transfer process in semidetached binary systems with tacking into account the magnetic field of accretor are presented.
