<h2>Description<a class="headerlink" href="#description" title="Permalink to this headline"></a></h2>
<p>Define a computation that returns the coordinates of the vertices
corresponding to the triangle-elements of a mesh created by the <a href="#id4"><span class="problematic" id="id5">`fix smd/wall_surface &lt;ls_&gt;`_</span></a>.</p>
<p>See <a class="reference external" href="USER/smd/SMD_LAMMPS_userguide.pdf">this PDF guide</a> to using Smooth Mach Dynamics in LAMMPS.</p>
<p><strong>Output info:</strong></p>
<p>This compute returns a per-particle vector of vectors, which can be
accessed 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>How-to discussions, section 6.15</span></a>
for an overview of LAMMPS output options.</p>
<p>The per-particle vector has nine entries, (x1/y1/z1), (x2/y2/z2), and (x3/y3/z3) corresponding
to the first, second, and third vertex of each triangle.</p>
<p>It is only meaningful to use this compute for a group of particles which is created via the
<a href="#id6"><span class="problematic" id="id7">`fix smd/wall_surface &lt;ls_&gt;`_</span></a> command.</p>
<p>The output of this compute can be used with the dump2vtk_tris tool to generate a VTK representation of the
smd/wall_surace mesh for visualization purposes.</p>
<p>The values will be given in <a class="reference internal" href="units.html"><em>units</em></a> of distance.</p>

<div class="section" id="restrictions">
<h2>Restrictions<a class="headerlink" href="#restrictions" title="Permalink to this headline"></a></h2>
<p>This compute is part of the USER-SMD 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>Making LAMMPS</span></a>
section for more info.</p>
