Using a repulsive vortex-vortex interaction model, we numerically investigate the dynamics of vortices in a drivendisordered two-dimensional superconductor. At low driving forces and temperatures, we have seen the evidence ofplastic and filamentary flow. At high driving forces and very low temperatures, the evidence of an ordering of themoving vortices is seen in the flux flow regime. Our results are in agreement with the previous simulation results andrecent experiments.
