Abstract
Numerical realization of the model of unstable 3D processes in gravitating gas systems with a self-consistent field in the Cartesian coordinates is considered. Evolution of the disk gas component is described by a system of equations of gas dynamics with regard to the equation for temperature, and Poisson-s equation for gravity potential. 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.
