Panel (a): Magnetic configuration of two current channels at simulation time = 0. The wFR is colored in green, and the small arcade in gray. The semitransparent slice shows the QSL distribution. Panel (b): Same magnetic configuration as panel a, but the slice shows a twist distribution. The slice is at x = 31.4 Mm. Panel (c): Same as panel a but at simulation time = 10. Panel (d): Same as panel b but at simulation time = 10. The slices shown in panels c and d are taken at x = 20.0 Mm. Panel (e): Magnetic configuration around the X-point. The dark blue patches represent QSL contours. The semitransparent green flux rope corresponds to the wFR, with several of its peripheral field lines highlighted in red. The small arcade and the several field lines formed through reconnection are depicted in gray. Two sets of external field lines are shown in orange and yellow, respectively. Panel (d): Zoomed-in view of the configuration shown in panel c.
