    • The elastic energy of a square well is similar to that of a nematic in a cylinder with strong anchoring in the circularly planar-polar configuration. Assuming the splay and bend elastic constants are equal, the elastic energy in a right cylinder of radius R is given by Fc =πKhln (R 2δ). The elastic energy of the square wells modeled here turns out to be about 25% larger than that of cylinders with the same base area.

    • Although the simulations were carried out for cross sections of infinitely long channels, rather than for square wells limited in extent, as in the experiments, nevertheless the overall behavior of the director field as a function of channel width is expected to be very similar to what occurs in square wells.
