Fig. 8


Two-dimensional wall-shock test at time t = 0.5. Left: density profiles for models described in Table 4: WHS1 (red), WHS2 (green), and WHSG (blue) in dots. The analytic result is the solid black line. The central panel depicts the particle distribution with density as color at t = 0.5 as obtained with GADGET-2 whereas the last panel is that of model WHS2. We note how WHS2 achieves lower particle disorder in the central region, and smaller density oscillations at the shock position than GADGET-2.
