“Mix Charge” simulations. (a) Coulomb model; location of the particles at 2 s. (b) Dipole model; location of the particles at 2 s. (c) Distribution of the coordination number of coarse particles at 2 s obtained with the Dipole model. (d) Coulomb model; coarse (black) and fine (gray) particles attached to at least one other particle. (e) Dipole model; coarse (black) and fine (gray) particles attached to at least one other particle. (f) Coulomb model; vertical position of fine and coarse particles (area between the q1 and q3 quartiles). (g) Dipole model; vertical position of fine and coarse particles (area between the q1 and q3 quartiles). (h) Evolution of the mean coordination number of coarse particles.
