A unified simulation framework for water phase transition based on particles.

Water phase transitions are fundamental and complex phenomena in nature. Previous researches usually studied every process during water phase transitions individually and simulated it separately. This is because the phase transition process of water is very complex. In this paper, we proposed a novel method to simulate the processes of water phase transitions uniformly. We firstly established PBMR (Position Based Material Representation) which is based on PBD (Position Based Dynamics) to describe all three different kinds of water material. And then, we designed a unified computational process to modeled water phase transitions. In our unified computational process, heat transfer mechanism and mass transfer mechanism were main concerns in our consideration. With our method, it is capable to simulate water phase transition uniformly.
