Query: Spin Dynamics for the Lebwohl-Lasher Model   A spin dynamics algorithm, combining checkerboard updating and a rotation
algorithm based on the local second-rank ordering field, is developed for the
Lebwohl-Lasher model of liquid crystals. The method is shown to conserve energy
well and to generate simulation averages which are consistent with those
obtained by Monte Carlo simulation. However, care must be taken to avoid the
undesirable effects of director rotation, and a method for doing this is
proposed.
