Abstract

Liquid crystalline materials in complex confinement geometries have lately attracted considerable attention because of several interesting physical phenomena residing in strong surface interaction effects. Following recent investigations, we propose a Monte Carlo simulation model for characterizing the molecular director configuration in a nematic liquid crystal cell having a defect cylindrical hole in a central region of one of the boundary substrates. The main results illustrate the director’s spatial profile and the local order parameter distribution for the proposed confining geometry, as well as the interaction field propagation through the bulk in the case of different anchoring regimes imposed at the boundaries..
