Problem about lammps

LAMMPS LAMMPS Mailing List Mirror

Hallo,

Now I am using lammps to simulate the laser ablation of metal films. With fs
laser the metal film can evaporate in a low lattice temperature. But in lammps
the atoms can only evaporate when the lattice temperature reach a high value.
So I want to ask, are there some methods, that can make the atoms to evaporate
in a low lattice temperature?

Thank You

first, please explain how you simulate the effect of the laser.
