Abstract

We report Monte Carlo simulations of a liquid crystal cell having a small hemispherical defect on one of its electrodes. Using the Lebwohl-Lasher model, we obtained the order parameter for the bulk region and inside the cavity. We concluded that the confinement and the geometry of the system play a crucial role for the behavior of the local nematic director..
