a problem about lattice

Dear All,

I am simulating the evaporation of argon droplet on a heating plate by molecular dynamic. I have a problem about how to set the lattice parameter. Because only the crystal have lattice, if I choose the liquid argon, how does it to gather in a formation of droplets. Please help me how to write input script.

Best wishes!

The lattice command has nothing to do with dynamics. It is only

used to define a length scale (and set of points) useful for some

other commands. Like create_atoms. Once you have put

atoms wherever you put them (data file, create_atoms, etc),

then the atoms interact via the pair style you defined and its

parameters (e.g. epsilon, sigma for LJ). The lattice command

has nothing to do with it at that point.
