<h2>Examples</h2>

<div class="section" id="description">
<h2>Description</h2>
<p>Define a computation that accesses the per-particle internal
conductive energy (u_cond), internal mechanical energy (u_mech),
internal chemical energy (u_chem) and
internal temperatures (dpdTheta) for each particle in a group. See
the <a class="reference internal" href="compute_dpd.html"><span class="doc">compute dpd</span></a> command if you want the total
internal conductive energy, the total internal mechanical energy, the
total chemical energy and
average internal temperature of the entire system or group of dpd
particles.</p>
<p><strong>Output info:</strong></p>
<p>This compute calculates a per-particle array with 4 columns (u_cond,
u_mech, u_chem, dpdTheta), which can be accessed by indices 1-4 by any command
that uses per-particle values from a compute as input. See
<a class="reference internal" href="Section_howto.html#howto-15"><span class="std std-ref">Section_howto15</span></a> for an overview of
LAMMPS output options.</p>
<p>The per-particle array values will be in energy (u_cond, u_mech, u_chem)
and temperature (dpdTheta) <a class="reference internal" href="units.html"><span class="doc">units</span></a>.</p>
</div>
<div class="section" id="restrictions">
<h2>Restrictions</h2>
<p>This command is part of the USER-DPD package. It is only enabled if
LAMMPS was built with that package. See the <a class="reference internal" href="Section_start.html#start-3"><span class="std std-ref">Making LAMMPS</span></a> section for more info.</p>
<p>This command also requires use of the <a class="reference internal" href="atom_style.html"><span class="doc">atom_style dpd</span></a>
command.</p>
