<h2>Description</h2>
<p>Write a text format file with the currently defined force field
coefficients in a way, that it can be read by LAMMPS with the
<a class="reference internal" href="include.html"><span class="doc">include</span></a> command. In combination with the nocoeff

<p class="last">The write_coeff command is not yet fully implemented in two
respects. First, some pair styles do not yet write their coefficient
information into the coeff file. This means you will need to specify
that information in your input script that reads the data file, via
the <a class="reference internal" href="pair_coeff.html"><span class="doc">pair_coeff</span></a> command.</p>
