Snapshots from final configurations of quasi-2D spherically restrained CG MD simulations of CA lattice assembly for εNN/kBT = 6.71 (color online). Top row: Flexible dimer model, ρ = 0.38 (A), 0.5 (B), and 0.6 (C). Bottom row: Rigid dimer model, ρ = 0.38 (D), 0.5 (E), and 0.6 (F). Color scheme as in Fig. 2.
