Thus the ghost keyword is suitable for static properties, like molecule IDs, but not for dynamic properties that change every step. For the latter, the code you add to LAMMPS to change the properties will also need to communicate their new values to/from ghost atoms, an operation that can be invoked from within a pair style or fix or compute that you write. £¨ http://lammps.sandia.gov/doc/fix_property_atom.html £© |
