3D visualisation of a subset of the braided coronal magnetic field, at t = 40 min. Magnetic field lines are traced from four photospheric sources (seed points are initiated within 0.25 Mm of the given coordinates). Field lines are coloured by their source location. Streamlines of the velocity field are initiated at the photospheric sources, and are coloured by vertical flow velocity v_z. The lower panel shows the same visualisation, now viewed from above.
