Potentials in MD++
This table contains information about the potentials use in MD++.
Name of Potential -> Symbol -> Types of Materials Used For
Molecular Dynamics -> md_gpp -> Any Material (not a potential), visualization tool
Finnis-SinClair -> FS_gpp -> Metals (FCC and BCC)Mo
Embedded Atom Method -> EAM_gpp -> Metals (FCC) Cu, Au
Lennard-Jones -> LJ_gpp -> Inert Gases Ar
Stillinger-Webber -> SW_gpp -> Si, Ge, C
Aluminum Glue -> AlGlue_gpp -> Al
Tersoff -> Tersoff_gpp -> Si, C, Ge
Brenner -> Brenner_gpp -> C, hydrocarbons
"Potential" Problems
These are some potential files we used in our simulations of molecular structures. Please note that since we use a variety of codes, the potential files will be in a variety of foremats. The most common codes used by our group are LAMMPS ( and ParaDyne) and MD++. These codes use different file formats for EAM potentials, so all files should specify which file format. We will also try to provide a reference describing the potential.
