thank you for your explanation. I will try to use GULP later for checking the EAM potential.
In the case of LAMMPS, I understood that this code is 'only' for dynamics simulation but not static simulation, in which we can check the reliability of the EAM potential. Does "write some scripts" mean that we must make script (input command file) to be able to use LAMMPS code? I am very grateful if you explain in a little more detail how to do this.
