Algodoo

A simulation of a tiny water droplet in air.

Simulation capabilities:
Latent heat of fusion, vaporisation.
Van De Waals, London dispersion force approximations.
Hydrogen Bonding

Caveats:
1* Hydrogen bonding is somewhat unrealistic (UNSOLVABLE)
Forces are only approximations (UNSOLVABLE)
Ice is denser than water (1*)

Simulation details:
Temperature: 285K
Pressure: 1 atm
Time scale: ~50 femtoseconds per second
