These are one-file C programs that generate tabulated embedded atom method (EAM) potentials from analytic formulas. They each write out a file in the DYNAMO setfl format which can be input by LAMMPS via the pair_style eam/alloy command.

The source files and potentials were provided by Gerolf Ziegenhain (gerolf at ziegenhain.com). You could modify these programs to write out your own EAM potentials in LAMMPS-compatible format.
