摘要：

We have performed the first computer simulation of a twisted nematic liquid crystal using non-spherical hard particles in modified periodic boundary conditions. The director profiles are stable, suggesting that the technique may usefully complement conventional simulations of unperturbed liquid crystals. We make preliminary calculations of the twist elastic constant K2 by measurement of intermolecular torques: the results are in moderately good agreement with those obtained from fluctuation expressions.
