Overview of the AIKEF simulation box. In the top-right corner, there is an exemplary unrefined block that is further divided into cells that define the grid resolution (size ratios: block to simulation box = cell to block). The black arrows denote the difference between the MASO and MSM coordinate system, which is shifted 0.2R_M in the +Z direction. The subsolar point is defined to be on the MSM X-axis; see modelled bow shock (green, solid line) and magnetopause (blue, dotted). The MSB2 trajectory with its closest approach is shown in red; the orange outline encloses the refined area (grid resolution doubled).
