Dust acoustic soliton stability in an unmagnetized dusty plasma is studied based on a PIC code simulation, by considering size distribution of dust grains. The electrons and ions are considered as hot, isothermal, and Boltzmann distributed components, and the dust grains are modeled as a fluid. The comparison of dust acoustic soliton parameters is made between a mono-sized dusty plasma and a Gaussian dust size distribution. The simulation results are also compared with analytical conclusions.
