ABSTRACT
We present a Monte Carlo (MC) simulation of a nematic film with boundary conditions that vary from a homogeneous to a homeotropic anchoring at one surface while having a homogeneous anchoring at the other one. The simulations are based on the Lebwohl–Lasher lattice spin model with suitable boundary conditions to mimic the cell. We have investigated temperature effects on the molecular organization inside the system by calculating the internal energy, the heat capacity and the standard nematic order parameter.
