Abstract: The mass transfer between the components of the magnetic cataclysmic variables occurs through the inner Lagrangian point. The results of 3D numerical simulations of the flow structure in magnetic cataclysmic variables show that the magnetic field of the accretor essentially influences the flow structure. In polars (with magnetic fields of 10–100 MG at the surface of the white dwarf) the material streaming from the donor splits into the several flows as soon as it leaves the inner Lagrangian point. These flows move along the magnetic field lines and reach the magnetic poles of the accretor. This picture does not correspond to the classical situation of the flow formation when material flows from the donor into the Roche lobe of the accretor along the ballistic trajectory. The aim of our study is to investigate in detail the features of the flow splitting in the vicinity of the inner Lagrangian point in classic polars.
