摘要：
We present detailed Monte Carlo (MC) simulations of a nematic film with antagonistic boundary conditions corresponding to homeotropic and homogeneous planar anchoring at the two surfaces. The simulations are based on the Lebwohl-Lasher lattice spin model with boundary conditions chosen to mimic the cell anchoring. We have investigated the model using both a standard Metropolis and a reweighting Monte Carlo method recently implemented for continuous systems.
