Eruptive process of the resultant flux rope after the flux feeding process with C_E = 2.23. Panels a–h: illustrate the magnetic configurations at different times, and the blue color depicts the distribution of the current density. Panel i: evolution of the height of the rope axis, and the times of panels a–h are marked by the vertical dotted lines in panel i. The green curves in panels a–h mark the outer boundaries of the flux ropes and the plasmoids.
