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