-//potfit// is a free implementation of the force-matching algorithm to generate effective potentials from ab-initio data.  +//potfit// is a free implementation of the force-matching algorithm to generate effective  
- +potentials from ab-initio reference data. 
-It was originally developed by Peter Brommer and was maintained at the [[http://www.itap.physik.uni-stuttgart.de|ITAP]]. It has recently found a new home here at [[http://www.sourceforge.net|sourceforge]]. +

 ===== Features ===== ===== Features =====
  
-  * Fit empirical potentials with the force-matching algorithm +  * Fit empirical potentials for molecular dynamics with the force-matching algorithm 
-  * Tabulated or analytic potentials are available +  * Support for tabulated, analytic and OpenKIM potentials 
-  * Different interactions like pair potentialsEAM, ADP and electrostatics available +  * These interactions are currently supported: 
-  Directly export the potentials to IMD, our high performance MD code  +    * pair potentials 
- +    * angular pair potentials (plain or with coulomb) 
-===== Download ===== +    * EAM and two-band EAM 
- +    ADP  
-//potfit/is available as open source software released under the [[license|GPL]]+    * electrostatics (coulomb and dipole interactions) 
- +    * MEAM 
-The latest version can be downloaded [[download|here]].+    * 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 =====
  
-===== Support =====+//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)
