Summary

[edit]
Description
English: Transition in group polarization induced by velocity change. The simulation was performed in unbounded conditions with a group of 100 fish with parameters , , , . The swimming speed of all fish is initially set to , linearly increases to in 60 s, is maintained to this value for 30 s, and then decreases back to in 60 s. Movie time is 5× real time. The group switches from shoaling to schooling dynamics (and back) as a consequence of the increase (and decrease) of the swimming speed. As it increases, the relative weight of the orientational interaction dominates the positional interaction, leading to a better polarization which triggers a motion of the center of mass of the group.
