Abstract

We present results of the 2D simulations of magnetorotational mechanism for the rotating magnetized cloud. It was found that amplification of the toroidal magnetic field leads to the transformation of the part of the rotational energy of the cloud to the kinetic energy of radial motion. A compression wave appearing in the transition region between the core of the cloud and the envelope transforms soon to the MHD shock wave and pushes away part of the envelope of the cloud. Time evolution of the thrown away mass and energy are given. Simulations have been made on the base of the conservative implicit Lagrangian scheme on triangular grid with grid reconstruction.
