<h2>Description</h2>
|
|
<p>Using an angle style of zero means angle forces and energies are not
|
|
computed, but the geometry of angle triplets is still accessible to
|
|
other commands.</p>
|
|
<p>As an example, the <a class="reference internal" href="compute_angle_local.html"><span class="doc">compute angle/local</span></a>
|
|
command can be used to compute the theta values for the list of
|
|
triplets of angle 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 angle style is defined,
|
|
this command cannot be used.</p>
|
|
<p>The optional <em>nocoeff</em> flag allows to read data files with AngleCoeff
|
|
section for any angle style. Similarly, any angle_coeff commands
|
|
will only be checked for the angle type number and the rest ignored.</p>
|
|
<p>Note that the <a class="reference internal" href="angle_coeff.html"><span class="doc">angle_coeff</span></a> command must be used for
|
|
all angle types. If specified, there can be only one value, which is
|
|
going to be used to assign an equilibrium angle, e.g. for use with
|
|
<a class="reference internal" href="fix_shake.html"><span class="doc">fix shake</span></a>.</p>
