Abstract
Monte Carlo simulations of lattice spin models are employed to investigate the creation of inversion walls in nematic films with specific boundary conditions. The simulations, based on the well known Lebwohl-Lasher potential, allow to produce simulated polarized microscopy images which are followed during their evolution and analysed for different film thicknesses.
