In the present study, the dynamic behaviors of the water droplet on heterogeneous surface were investigated using molecular dynamics simulation. The surface consisted of the plat plate and the pillar structure which had different surface energy each other. We conducted the simulation in two steps. As a result of the first step, an initial water cube reached an equilibrium state as a water droplet. In the second step, we applied a constant body force to the static water droplet obtained from the first step and evaluated the dynamic behaviors of the water droplet. The dynamic behaviors of the water droplet, which could be classified according to their shapes, depended on the pillar characteristics (e.g., the surface energy and the height) and the magnitude of the applied body force.
