Reconnection of orthogonal (NN6) B_axial=1+cos(r*pi/R) flux tubes

Reynolds number Rm=R*v_A/(pi*eta)=3750

Initial peak velocity magnitude: v_A/20, as opposed to v_A/10, or v_A/5

Field in vertical tube runs top to bottom, in horizontal tube runs left to right (so mutual helicity is negative, reconnection should generate left handed twist).

Movie of B/9 isosurfaces of the magnetic field.

Movie of fieldlines running through lagrangian trace elements placed in the plasma.

Only fieldlines running through elements initially in the vertical flux tube are shown.

The horizontal flux tube is in front of the vertical flux tube from this viewpoint.

Fieldline area at any point along the fieldline is proportional to |B| there. Any part of a fieldline at |B| less than 1/10th of the global maximum is not plotted.

Energy vs time for the reconnection simulation and the reference simulations. The reference simulation is a single tube and the same S with no initial velocity.
