Resistivity η (left panel) and rest-mass density ρ (right panel) at the final time of the simulation (t ∼ 0.5 s) for the different resistivity cases. The dashed black line represents the tracer contour line at level 1%, while the solid lines are only designed to delimit the different cases. We note that in this and all the 2D plots, the angle θ is between 0° and 90° and the negative cylindrical coordinates are simply a post-processing transformation to enhance the comparison quality.
