MEAM Potential

LAMMPS LAMMPS General Discussion

I am trying to use MEAM potential for Al 6061. I found one paper at database and used it. Now I am getting an error in parameter file.

ERROR: Error in MEAM parameter file: keyword Cmin has out of range element index (src/MEAM/pair_meam.cpp:600)
Last command: pair_coeff * * Al_6061_library.meam Al Si Mg Al_6061.meam Al Si Mg

Can you please enlighten me?

@fahad0213 As a person that is new here, please start by doing a few things to acclimate yourself to how we do things here.

  • Post to the correct category. Your question is about LAMMPS not the material project
  • Please read the forum guidelines (all of them) and try to follow them closely. The better you do this, the better your chance to get good help
  • Part of being a “good citizen” is that you should always mention which specific LAMMPS you are using (and don’t say “the latest” because that can change any day, and many people that say they have “the latest” are actually wrong about it) and what platform you are running on.
  • If you are encountering an error, you have to provide a minimal example and the corresponding files to easily reproduce it. If you cannot attach them here upload them elsewhere and share the link.

Unfortunately, no. You are doing something wrong, but since I cannot read your mind of that of your computer and don’t know what that is. The only thing that I can say is that you may be using a n outdated LAMMPS version, because the reported line number in the error message neither matches the development version or the stable version.

I could solve the problem. Thank you very much for your advice.

For the sake of your fellow LAMMPS users that may run into the same problem, would you mind explaining how you solved this problem?
