Abstract
A modeling of the nucleation and dynamical behavior of defects from an inhomogeneous surface configuration using fast Q-tensor method is realized. On modeling the defect nucleation and dynamics, A fast Q-tensor method is applied. From the numerical modeling, we confirmed that surface inhomogeneity which makes strong strain energy in the local liquid crystal director field could cause defects. Experimental result has compared with numerical modeling in order to verify the simulation of the defect nucleation.
