Snapshots displaying the velocity and concentration fields (upper and bottom rows, respectively) with streamlines during the sedimentation of dendritic particles in viscous fluid and gravity of \(0.001g\). The snapshots are taken (from left to right) after \(8\;\times 1{0}^{4}\) steps (1.6 s), \(2.8\;\times 1{0}^{5}\) steps (5.6 s), \(6\;\times 1{0}^{5}\) steps (12 s) and \(1.8\;\times 1{0}^{6}\) steps (36 s). Coloring is as in Fig. 2. The simulation was performed on a 2000 × 2000 grid. For the corresponding animation see Supplementary Movie 4.
