An example of a typical initial configuration of the N = 300 polydispersed pedestrians randomly located in a 15 m × 15 m room with an exit of width b = 3.0Dm. A random selection of 20 desired velocities in the evacuation room and the same for the second room, pictured with red and blue arrows, respectively. In the evacuation room, desired velocities are vectors pointing from particle positions to the center of the exit, whereas in the second room, the desired velocities point to a random position at the discontinuous vertical line. The employed parameters are τ = 0.5 s, A = 2 × 103 N, B = 0.08 m, H = 1.2 × 105 kg s−2, and γ = 2.4 × 105 kg m−1 s−1.
