摘要
We propose a numerical approach to the calculation of microstructural evolution in forms of the atomic density evolution. The modulation of the atomic density wave is driven by the minimization of the free-energy functional, which includes an effective pair potential term with softened core. As applications, we report simulation results of solidification, grain growth, and annealing for a one-component system in two dimensions.
