<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
|
|
option of <a class="reference internal" href="write_data.html"><span class="doc">write_data</span></a> this can be used to move
|
|
the Coeffs sections from a data file into a separate file.</p>

<p class="first admonition-title">Note</p>
|
|
<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>
