Molecular dynamics simulation of water

[Gediminas]

Hello,

I would like to learn how to model water and its evaporation using molecular dynamics simulation. Perhaps there is anyone who has already done similar simulations and could answer few simple questions such as: What criteria should satisfy water molecule models for this kind of simulation? What could be best choise as water molecule model? What is the best free sofware for doing this kind of calculatins?

Best regards,

Gediminas
