Solar eruptions often show the rotation of filaments, which is a manifestation erupting magnetic flux rope (MFR). Such MFR can be induced by either torque exerted background shear-field component (which an external cause) or relaxation twist (an internal cause). For given chirality field, both and drivers cause same direction. Therefore, it remains elusive from direct observations mechanism yields dominant contribution to rotation. In this paper, we exploit full MHD simulation solar eruption...
