<h2>Description</h2>
<p>Using an bond style of zero means bond forces and energies are not
computed, but the geometry of bond pairs is still accessible to other
commands.</p>
<p>As an example, the <a class="reference internal" href="compute_bond_local.html"><span class="doc">compute bond/local</span></a>
command can be used to compute distances for the list of pairs of bond
atoms listed in the data file read by the <a class="reference internal" href="read_data.html"><span class="doc">read_data</span></a>
command. If no bond style is defined, this command cannot be used.</p>
<p>The optional <em>nocoeff</em> flag allows to read data files with a BondCoeff
section for any bond style. Similarly, any bond_coeff commands
will only be checked for the bond type number and the rest ignored.</p>
<p>Note that the <a class="reference internal" href="bond_coeff.html"><span class="doc">bond_coeff</span></a> command must be used for
all bond types. If specified, there can be only one value, which is
going to be used to assign an equilibrium distance, e.g. for use with
<a class="reference internal" href="fix_shake.html"><span class="doc">fix shake</span></a>.</p>
