Spacetime diagrams of the stratified net flux simulations, showing the evolution of the horizontal averaged radial (top) and azimuthal (bottom) fields for both GDSPH (left) and TSPH (right) in the case of α_B = 1 with a resolution n_x = 58. At this resistivity only GDSPH reproduce the butterfly diagram, where for TSPH a strong positive azimuthal field permeates the disk corona (|z|> 2). The azimuthal field is additionally amplified as the simulation goes on and starts to propagate into the central disk region.
