Azimuthal part of the flow and magnetic field in the N4631 run. Top: Cuts of U_φ along selected heights z, as indicated by the legend in the bottom plot (shown only there for space). Dashed and solid lines represent the initial configuration and the final converged state, respectively. Bottom: Cuts of the angle between B and U (dashed), and between B and its projection onto the poloidal plane, for the same colorcoded height levels as in the upper plot. The curve for z = 0 is omitted due to symmetry. A horizontal (dotted) line at 90^∘ is included for reference.
