(a) Polycrystalline Cu (f.c.c.) sample with 1000 grains. Atoms are colored by coordination number. Atomic positions were averaged over multiple molecular dynamics frames. (b) Powder diffraction profiles for polycrystalline samples with different numbers of grains, normalized by atom count. The largest differences appear in the low-angle region and in the relative peak intensities.
