Latest commit c7d8b9e Sep 13, 2018

gosam is a bunch of Python scripts:

  • -- to generate atomistic model of grain boundary (bicrystal) with a coincidence site lattice (CSL) boundary in the PBC box,
  • -- to generate monocrystal in PBC box (atomistic model),
  • -- create crystalline grains of given shape, with vacancies, thermal vibrations, etc.
  • -- convert between several file formats (AtomEye cfg, VASP POSCAR, LAMMPS, DL_POLY, XMOL XYZ).
  • -- to list coincident site lattice (CSL) grain boundaries in cubic crystals

Prerequisites: Python 2 and numpy. additionally requires the qhull program.

Installation: download, unpack if you've downloaded zip file, and use from command line.

Usage: See documentation in the wiki and feel free to e-mail me with questions. Or open Github issue. Also, most of the programs print basic usage instructions when invoked without parameters.
