    Computational modeling of micro- or nanostructure evolution is widely studied in materials engineering field. Phase field approach is a novel approach to simulate the various fields that characterize the micro- and nanostructures. Indeed, many phenomena related with the microstructure evolutions, such as a dendritic growth of materials and spinodal decomposition have been studied using phase field approach. However, the phase field approach has some limitations to model the natural properties arise from their crystalline phases because the phase field represents the fields that are spatially uniform in equilibrium. Recently, the phase field crystal method is proposed to overcome the limits. Moreover the PFC model can consider the phenomena on an atomic length scale and a diffusive time scale in contrast to molecular dynamics which is constrained to evolve at the scale of femtosecond. Here, we introduce the PFC in modeling of microstructure evolution and present a great potential of it.
