Modeling Of Molecular Reorientation In Nematic Liquid Crystals

In this paper, the modeling of molecular reorientation in nematic liquid crystals is described. The theoretical model is based on Frank-Oseen elastic theory. By minimizing the equation on free energy, an equation describing molecular reorientation is obtained. To get a solution, two numerical methods (Successive Over-Relaxation and Multigrid) are employed and compared for the numerical results of director orientation and computation time.
