Dear LAMMPS users,
I am trying to model the interaction between Nb and H. Searching the literature, I found out that 12-6 potentials can not very well define the van der Waals interactions in this system. The best potential available has the form: Aexp(-B/r). I searched the LAMMPS manual but I couldn’t find this form. I would appreciate any input that helps me apply this form in LAMMPS.
Thanks,
Iman.
