Particle evolution for r = 10 and no interactions (Є = 10000).Evolution under non-homogeneous diffusion of 1,000 particles (depicted in green) for 500 time step. A square slow patch on the upper left corner has a diffusion ratio of 10 and particles interaction strength is set to 10000. In this last experiment,the over-concentration appears first on the border of the patch. The difference in the phase transition is extremely more pronounced in the slow patch.
