[lammps-users] Query about Defining crystal geometry

LAMMPS LAMMPS Mailing List Mirror

Hello guys
I am Irslan Ullah, I am very beginner to LAMMPS, after running examples, I am trying to do an energy minimization run for my SiC crystal, I assume we can’t use any .cif file as data file for read_data command. I want to ask at this start point , which is best option,

  1. making manually a data file for read_data command,
  2. using create_atoms command to generate the geometry input.

LAMMPS does not care how you enter your geometry for as long as you do it correctly.
Either is suitable for the problem at hand.

You need to generate the Lammps Data file.
