review text: It is known that the accretion of medium in astrophysical discs occurs by rejection of the moment from the center to the periphery. Here, one of the possible rejection mechanism, i.e., the large vortex structures are considered. Such structures arise in the case of non-stable rotational motion in the presence of a weak magnetic field. A numerical scheme of Godunov's type is used in simulations of rotational flows of medium in the astrophysical gas cloud.
