Three-dimensional structure of our steady-state solar wind simulation. Left: radial-velocity structure (colour map) and magnetic field lines (grey lines). Right: Close-in structure of the magnetic field within 10 R_⊙. The spherical surface denotes the inner boundary of our domain and shows the surface field strength of the radial magnetic field component B_r as a colour gradient between the north and south pole of the domain. The grey lines represent the connected field lines.
