Effects of the resolution on the evolution of the metallicity profile of particles that received feedback in our fiducial model “a”, with a resolution of N = 16³a) and N = 128³b). Each curve corresponds to a different times, 0.6, 2.4, and 4.7 Myr after the supernova explosion. The upper right panel shows the iron distribution function which, in this particular experiment, is independent of time.
