Abstract
The results of parallel program design for numerical model of dynamics of self-gravitation gas structures are presented. Model is based on decision of gas dynamics equations and Poisson equation for gravity potential. The initial system of the equations of gas dynamics is solved by the Fluids-in-Cells method with energy balance correction. The three-dimensional problem is solved with a glance of cooling action in Cartesian display. Adequate results of colliding galaxies process are obtained.

Key Words
gravitational instability, galaxies formation and dynamics, hydrodynamics models, astrophysics, effective parallel algorithm
