Densities at t = 0.2 (which corresponds to ~ 0.5 crossing time of the wave) of the five dust species and of the gas (divided by 2) along with the eigenmode described in Table D.1. Dots are the numerical solutions. Continuous lines are the linear solutions. The time step is divided by a factor of 10 (C_CFL = 0.1) to achieve the convergence in time for this resolution (level 6, 64 points).
