~~NOTOC~~ ====== Welcome to the potfit wiki ====== ----- //potfit// is a free implementation of the force-matching algorithm to generate effective potentials from ab-initio reference data. ===== Features ===== * Fit empirical potentials for molecular dynamics with the force-matching algorithm * Support for tabulated, analytic and OpenKIM potentials * These interactions are currently supported: * pair potentials * angular pair potentials (plain or with coulomb) * EAM and two-band EAM * ADP * electrostatics (coulomb and dipole interactions) * MEAM * Stillinger-Weber * Tersoff and modified Tersoff * [[https://openkim.org/|OpenKIM]] models * Directly export the potentials to [[http://imd.itap.physik.uni-stuttgart.de|IMD]] or [[http://lammps.sandia.gov|LAMMPS]]. ===== Requirements ===== //potfit// is provided as C source code which requires the following: * a Python runtime for the //potfit// build system * a C99 compliant compiler (tested with GCC, Clang, and ICC) * one of the following LAPACK implementations: * Intel MKL * Accelerate Framework on Mac OS * an MPI implementation for parallel execution (tested with OpenMPI)
