<h2>Description<a class="headerlink" href="#description" title="Permalink to this headline">¶</a></h2>
|
|
<p>The <em>mie/cut</em> style computes the Mie potential, given by</p>
|
|
<img alt="_images/pair_mie.jpg" class="align-center" src="_images/pair_mie.jpg" />
|
|
<p>Rc is the cutoff and C is a function that depends on the repulsive and
|
|
attractive exponents, given by:</p>
|
|
<img alt="_images/pair_mie2.jpg" class="align-center" src="_images/pair_mie2.jpg" />
|
|
<p>Note that for 12/6 exponents, C is equal to 4 and the formula is the
|
|
same as the standard Lennard-Jones potential.</p>
|
|
<p>The following coefficients must be defined for each pair of atoms
|
|
types via the <a class="reference internal" href="pair_coeff.html"><em>pair_coeff</em></a> command as in the examples
|
|
above, or in the data file or restart files read by the
|
|
<a class="reference internal" href="read_data.html"><em>read_data</em></a> or <a class="reference internal" href="read_restart.html"><em>read_restart</em></a>
|
|
commands, or by mixing as described below:</p>
|
|
<ul class="simple">
|
|
<li>epsilon (energy units)</li>
|
|
<li>sigma (distance units)</li>
|
|
<li>gammaR</li>
|
|
<li>gammaA</li>
|
|
<li>cutoff (distance units)</li>
|
|
</ul>
|
|
<p>The last coefficient is optional. If not specified, the global
|
|
cutoff specified in the pair_style command is used.</p>
|
|
<hr class="docutils" />
|
|
<p><strong>Mixing, shift, table, tail correction, restart, rRESPA info</strong>:</p>
|
|
<p>For atom type pairs I,J and I != J, the epsilon and sigma coefficients
|
|
and cutoff distance for all of the mie/cut pair styles can be mixed.
|
|
If not explicity defined, both the repulsive and attractive gamma
|
|
exponents for different atoms will be calculated following the same
|
|
mixing rule defined for distances. The default mix value is
|
|
<em>geometric</em>. See the “pair_modify” command for details.</p>
|
|
<p>This pair style supports the <a class="reference internal" href="pair_modify.html"><em>pair_modify</em></a> shift
|
|
option for the energy of the pair interaction.</p>
|
|
<p>This pair style supports the <a class="reference internal" href="pair_modify.html"><em>pair_modify</em></a> tail
|
|
option for adding a long-range tail correction to the energy and
|
|
pressure of the pair interaction.</p>
|
|
<p>This pair style writes its information to <a class="reference internal" href="restart.html"><em>binary restart files</em></a>, so pair_style and pair_coeff commands do not need
|
|
to be specified in an input script that reads a restart file.</p>
|
|
<p>This pair style supports the use of the <em>inner</em>, <em>middle</em>, and <em>outer</em>
|
|
keywords of the <a class="reference internal" href="run_style.html"><em>run_style respa</em></a> command, meaning the
|
|
pairwise forces can be partitioned by distance at different levels of
|
|
the rRESPA hierarchy. See the <a class="reference internal" href="run_style.html"><em>run_style</em></a> command for
|
|
details.</p>
