Mass of shocked ²⁸Si (upper panel) and ⁵⁶Fe (lower panel) vs. time for the spherically symmetric explosion (green lines) and for model Fe-R5-D750-V7 (red lines, see Table 1). Solid and dashed lines show the shocked mass from cells within 45° of the z-axis and from 15° of the equatorial plane respectively, while the dotted lines show the mass from the others cells. The shocked mass is normalized to the total mass of the relative element in the region considered.
