write\_coeff command
====================

Syntax
""""""


.. parsed-literal::

   write_coeff file

   file = name of data file to write out

Examples
""""""""


.. parsed-literal::

   write_coeff polymer.coeff

Description
"""""""""""

Write a text format file with the currently defined force field
coefficients in a way, that it can be read by LAMMPS with the
:doc:`include <include>` command. In combination with the nocoeff
option of :doc:`write\_data <write_data>` this can be used to move
the Coeffs sections from a data file into a separate file.

.. note::

   The write\_coeff command is not yet fully implemented as
   some pair styles do not output their coefficient information.
   This means you will need to add/copy this information manually.
