Results of n-body simulations of self-gravitating systems containing 100,000 particles are presented. A program based on the particle-mesh method is used to compute the evolution of a hot stellar-disk till an oval configuration at the center is formed. The system is evolved again from this point onwards a) with halo, b) without halo, and c) with the halo but with total mass of the system reduced to that of case b. Results are presented in form of a diagram showing the development of ellipticity.
