Simulation of the collapse of a rotating gas cloud on triangular reconstructing lagrangian grid
Abstract
In this paper we consider 2D numerical simulation of the gravitational collapse of a rotating gas cloud. Calculations were made using numerical scheme in Lagrangian variables on triangular irregular grid with grid reconstructing procedure. The most important result is that at the end of calculations flattened disk-shaped body is formed. Previous numerical simulations which have been made in Eulerian coordinate system for the same initial conditions led to ring-shaped body formation. Our results qualitatively coincide with simulations made in Lagrangian coordinates by other authors.
