Snapshots that show the velocity field and particle position during the sedimentation of 30 circular particles. The snapshots (from left to right) show the initial arrangement and the state of the system after \(1.4\;\times\;1{0}^{5}\) steps (2.8 s), \(2.4\;\times\;1{0}^{5}\) steps (4.8 s), \(3.2\;\times\;1{0}^{5}\) steps (6.4 s), \(4\;\times\;1{0}^{5}\) steps (8 s) and \(8.4\;\times\;1{0}^{5}\) steps (16.8 s). The white lines stand for the streamlines, while the arrows indicate the flow direction. The simulation was performed on a 540 \(\times\) 1024 grid. For the corresponding animation see Supplementary Movie 2.
