Evolution of the current sheet in the 2D flux cancellation experiment for the Gudiksen-11 resistivity model at different times (columns). Top: temperature maps zoomed in on the region around the elongated current sheet. Bottom: corresponding maps of the inverse characteristic length . The rectangle marks the region around the current sheet, and the inflow parameters are measured at the line segments AB and CD. S_h and S_l are the top and bottom of the current sheet, respectively.
