<h2>Description<a class="headerlink" href="#description" title="Permalink to this headline">¶</a></h2>
<p>Define a computation that extracts additional values calculated by a
bond style, sums them across processors, and makes them accessible for
output or further processing by other commands. The group specified
for this command is ignored.</p>
<p>The specified <em>bstyle</em> must be a bond style used in your simulation
either by itself or as a sub-style in a <a class="reference internal" href="bond_hybrid.html"><em>bond_style hybrid</em></a>
command.</p>
<p>This compute is useful when using <a class="reference internal" href="bond_hybrid.html"><em>bond_style hybrid</em></a>
if you want to know the portion of the total energy contributed by one
sub-style.</p>
<p><strong>Output info:</strong></p>
<p>This compute calculates a global scalar which is the contribution of
the named bond style to the bond energy <em>ebond</em>.</p>
<p>The scalar value calculated by this compute is “extensive” and will be
in energy <a class="reference internal" href="units.html"><em>units</em></a>.</p>
