Cross-section Z_MSM = 0 inside the simulation domain for case A: (top) electron and ion number densities, (middle) U_x and U_y components of the plasma bulk velocity, and (bottom) E_x and E_y components of the self-consistent electric field, normalized to their corresponding initial values, at the end of run (ω_Lit = 10). The white contour in the top and bottom panels marks the boundary that separates the higher density bulk of the plasma from its more tenuous regions. The magenta curve is the magnetopause.
