Nucleation and growth processes of cavitation bubble in water are simulated by molecular dynamics (MD) method. The water molecule is approximated by a particle with Lennard-Jones potential. The simulated model consists of a cube shaped decompression MD cell under periodic boundary condition. The gas and liquid phases are defined by number density. The growth process of cavitation babbles is visualized by the number density as a continuous quantity which is converted from the molecular configuration as a discrete quantity.
