Left panel: density distributions in the (x, 0, z) plane at the end of simulation time for a SN explosion with a large-scale anisotropy (upper quadrants) (runs Fe-R4-D750-V6 and Fe-R4-D750-V6-512pt in Table 1) and for a spherically symmetric explosion (lower quadrants), at low resolution (256³ grid points; left quadrants) and high-resolution (512³ grid points; right quadrants). Right panel: same but for color-coded images of the logarithm of the mass fraction distributions of Fe (red), Si (green), O (blue). In the upper quadrants of each panel, the black contours enclose the computational cells consisting of the original anisotropy material by more than 10% (dotted line)and 50% (solid line). The white dashed line represents the approximate position of the forward shock.
