FLYBY1 ((a) and (b)) and FLYBY2 ((c) and (d)): closed (magenta) and open (blue) magnetic field lines viewed in the xy-plane ((a) and (c)) and xz-plane ((b) and (d)) at t = 0 (left), t = 30 (center) and t = 50 (right) time steps. An animation of the magnetic field lines viewed in the xy-plane for FLYBY1 (left panel) and FLYBY2 (right panel) running from time step 0 to 50 is provided online.
