Hi, all

I am now using MEAM in lammps. When calculating the pair potential for element, lammps calculates the total energy of the reference structure as

E=-E0* { 1+a(rij) }* exp{-a(rij)}

I wonder whether I can rewrite this equation with the other universal equation proposed by Rose ( Phys Rev.B (1984) ) with two more adjustable parameters?? How to do this modification?

Thanks a lot!
