Comparison against the axisymmetric and the fully 3D simulations. The density (top part) and radial magnetic field (bottom part) are shown in the left panel, while the normalized parallel electromagnetic field (top part) and the jet-dissipated power (bottom part) are shown in the right panel. The left part of each panel represents the case S2V, while the right part represents the cut of the 3D simulation at ϕ = π/2 and θ ≥ π/2.
