Abstract

Analytical dependences of rotating self-gravitating gas as a result of nonstationary processes three-dimensional modeling in the gravitating gas system with a self-consistent field are received. Numerical realization of the model of unstable 3D processes in gravitating gas systems with a self-consistent field in the Cartesian coordi-nates is considered. A modified rotation-invariant fluids-in-cell method for numerical realization of equations of gas dynamics is considered. Results of applying the numerical model in a spatial case are presented.
