- W1970899314 abstract "In this study, a novel algorithm to solve the position of a nematic liquid crystal molecular director inside a device has been proposed. The formulation for minimizing the Gibbs free energy, composed by the free energy deformation (Frank-Oseen equations) minus the electrical energy, has been established using a vectorial representation of the director. The three liquid crystal elastic constants have been considered. The differential equations involved have been solved by applying numerical methods, using an algorithm developed by the authors. It has been compared with other techniques and the main advantages are that the new algorithm is faster and more accurate than other previous methods such as finite difference method (FDT) or a boundary value problem solver of MATLAB (bvp4c). Simulation program is also a powerful tool for analyzing other liquid crystal properties such as refractive index and permittivity as a function of voltage. To validate the simulation results, they have been compared with some measurements of a nematic liquid crystal device manufactured for that purpose. The comparison of birefringences simulated and measured show results that are fairly in agreement. This work also aims to provide a software simulation tool easy to reprogram for more complex devices." @default.
