Tabulated potentials

A good starting point for any binary system potential would be the single element potentials and maybe a combination of both for the mixed potential.

Format 3

A sample format 3 potential file for a binary system for an EAM potential is available with or {{:format_3.pot.txt|without}} the #G header line.

Format 4

A sample format 4 potential file for a binary system (EAM potential) is available here (with the ''#G'' header line).

Analytic potentials

Starting potentials for analytic potentials can be generated with the makeapot script.

There are several examples available for the different interactions:
