[lammps-users] How to generate EAM potential?

Dear lammps users

I’ve been using EAM potentials for a while, and I am wondering how to generate a EAM potential on my own. I noticed that there is a tool coming along with the Lammps package to generate a EAM potential. But still I am confused, what should I do if I want to modify a EAM potential that already exists. And could somebody please provide me more stuff specifying the steps and the theories?

Thanks!

Dear lammps users

dear <unknown>,

I’ve been using EAM potentials for a while, and I am wondering how to
generate a EAM potential on my own. I noticed that there is a tool
coming along with the Lammps package to generate a EAM potential. But

if you look closely, that tool only takes existing parameters
and creates mixed potential files for alloys from them.

still I am confused, what should I do if I want to modify a EAM
potential that already exists. And could somebody please provide me
more stuff specifying the steps and the theories?

how about looking at relevant publications?
in case you have not noticed, the LAMMPS documentation
contains lots of references to relevant publications
that describe the methods that are implemented.

however, if you want somebody to spell it out for you
in every little detail and give you a personal tutorial,
i suspect you are out of luck unless you have something
to offer in return that would make it worth the effort.

cheers,
