We employed molecular dynamics simulation to explore the melting dynamics of Gold thin film due to ultrashort high-intensities laser irradiation. The film has dimension of 10 nm x 10 nm in lateral periodic condition and thickness 10 nm with free condition. The system is suppressed by the laser energy slightly above melting threshold and simulated under homogeneous and instantaneous energization. Within several ps the system already melt and the evolution are followed based on trajectory of each atom dynamics. During the expansion of the film, we also performed the local structure change based on Common Neighbor Analysis (CNA) method. Structure factor analysis indicated that the film is melted completely at the end of simulation, t = 20 ps.
