Finite element analysis of a nematic liquid crystal Landau-de Gennes model with quartic elastic terms
<|reference_start|>Finite element analysis of a nematic liquid crystal Landau-de Gennes model with quartic elastic terms: In arXiv:1906.09232v2, Golovaty et al. present a $Q$-tensor model for liquid crystal dynamics which reduces to the well-known Oseen-Frank director field model in uniaxial states. We study a closely related model and present an energy stable scheme for the corresponding gradient flow. We prove the convergence of this scheme via fixed-point iteration and rigorously show the $\Gamma$-convergence of discrete minimizers as the mesh size approaches zero. In the numerical experiments, we successfully simulate isotropic-to-nematic phase transitions as expected.<|reference_end|>
