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.
two_band_fecr.py
----------------

Python script that writes the "s-band" overlay file (DYNAMO setfl
Finnis-Sinclair / eam/fs format) for a two-band ("double-band") EAM
potential, such as the Fe-Cr models of Olsson et al. (Phys. Rev. B 72,
214119 (2005)) and Bonny et al. (Phil. Mag. 91, 1724 (2011)).  Such a
model is an ordinary EAM with an extra embedding term and runs in LAMMPS
as a hybrid/overlay of two eam/fs potentials, without modifying LAMMPS;
see doc/src/Howto_eam_overlay.rst.  Run with --demo for a self-contained,
runnable example, or --help for all options.
