Abstract
Thermal fluctuation for the time-dependent Ginzburg-Landau simulations is c onsidered on the basis of the ensemble theory and the fluctuation-dissipati on relation. The treatment for evaluating the thermal fluctuation for a non conserved system is proposed and the formula for the fluctuation is present ed. The magnitude of the fluctuation depends on the coarse-grained volume a nd the curvature of the free-energy function at thermal equilibrium. The va lidity of the formula is verified by numerical simulation.
