(color online) A geometrical model showing (a) a smooth boundary (green line) for ζ = 0.286 rounded squares and (b) a zigzag boundary (red line) for ζ = 0.667 rounded squares between two rows of a rhombic lattice along one lattice direction at η = 0.830; (c)–(d) Snapshots from simulations of RB phase at η = 0.830 show (c) a smooth boundary (green line) along which gliding is observed for ζ = 0.286 rounded squares and (d) rough boundaries (red lines) and thus no gliding motion for ζ = 0.667 rounded squares.
