Simulated molecular alignment configurations. Calculated structures for 5CB on circular SU8 posts, colored by energy density of each elastic deformation mode. Post height is \(h=0.2\ \upmu{\mathrm{m}}\) for pinwheel, radial, and boojum structures, and \(h=2\ \upmu{\mathrm{m}}\) for uniform structure
