Results of the magnetorotational explosion simulations are presented for differentially rotating magnetized cloud. Differential rotation leads to the amplification of the toroidal component of the magnetic field. The part of the rotational energy of the cloud is transformed to the kinetic energy of the radial motion. Part of the matter ~7% of the mass of the cloud (3.3% of the final gravitational energy of the cloud) gets radial kinetic energy which is larger than its potential energy and can be thrown away to the infinity. This part of the cloud carries about 30% of the initial angular momentum of the cloud. For the simulations we used specially developed completely conservative implicit 2D Lagrangian scheme on triangular grid with grid reconstruction. .
