Results of 2D numerical simulation of magnetorotational mecha-
nism of supernova explosion are presented. Simulation has been
done for the real equations of state, energy neutrino losses has
been taken into account. Simulation has beendone on the base
of Implicit Lagrangean schemeon triangular grid with grid recon-
structuring. It is shown that due to the differential rotation of the
star toroidal component of magnetic field appears and grows with
time. Rotational momentum transfers outwards by the growing
with time toroidal magnetic field. With the evolution of thepro-
cess, part of the envelope of the star is ejected. The amount of the
thrown-off mass and energy is estimated. The results of the sim-
ulation could be used as a possible explanation of the supernova
explosion picture.
