The distributed QC code only supports EAM potentials with parameter files stored in DYNAMO format. The "Potentials" directory contains the parameter files (*.fcn) and accompanying *.mat files that define the crystal structure and *.ref files with reference information. You can add more materials by following this format. (See also section 3.1 in the QC Reference Manual.) You can find additional parameterizations on the OpenKIM (https://openkim.org
) or NIST IPR (https://www.ctcms.nist.gov/potentials/
) potential repositories.
