(color online) Comparison of the contact force between grains for (a) the center exit and (b) the lateral exit. The exit size is set to D/d = 10.0. The darker color indicates higher contact force in units of the gravitational force of one grain. The blue (25.0) and olive (50.0) lines are marked to emphasize the profile of arch above the exit.
