Movie S5. D. grandis CFD simulation with a 5-μm-wide vane (brown) and 1.1 million computational cells. Shown are passive tracer particle trajectories in
the yz plane perpendicular to the flagellar plane of beat. Particle velocities are much less time dependent in this plane compared with the plane parallel to
this (Movie S4).
