<h2>Description<a class="headerlink" href="#description" title="Permalink to this headline"></a></h2>
<p>Assign each atom type in the system to be one of 3 kinds of atoms
within the Drude polarization model. This compute is designed to be
used with the <a class="reference internal" href="tutorial_drude.html"><em>thermalized Drude oscillator model</em></a>. Polarizable models in LAMMPS
are described in <a class="reference internal" href="Section_howto.html#howto-25"><span>this Section</span></a>.</p>
<p>The three possible types can be designated with an integer (0,1,2)
or capital letter (N,C,D):</p>
<ul class="simple">
<li>0 or N = non-polarizable atom (not part of Drude model)</li>
<li>1 or C = Drude core</li>
<li>2 or D = Drude electron</li>
</ul>

<div class="section" id="restrictions">
<h2>Restrictions<a class="headerlink" href="#restrictions" title="Permalink to this headline"></a></h2>
<p>This fix should be invoked before any other commands that implement
the Drude oscillator model, such as <a class="reference internal" href="fix_langevin_drude.html"><em>fix langevin_drude</em></a>, <a class="reference internal" href="fix_drude_transform.html"><em>fix drude/transform</em></a>, <a class="reference internal" href="compute_temp_drude.html"><em>compute temp/drude</em></a>, <a class="reference internal" href="pair_thole.html"><em>pair_style thole</em></a>.</p>
