<h2>Description<a class="headerlink" href="#description" title="Permalink to this headline">¶</a></h2>
<p>The fix performs explicit time integration for particles which interact according with the Total-Lagrangian SPH pair style.</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>The <em>limit_velocity</em> keyword will control the velocity, scaling the norm of
the velocity vector to max_vel in case it exceeds this velocity limit.</p>

<h2>Restart, fix_modify, output, run start/stop, minimize info<a class="headerlink" href="#restart-fix-modify-output-run-start-stop-minimize-info" title="Permalink to this headline">¶</a></h2>
<p>Currently, no part of USER-SMD supports restarting nor minimization. This fix has no outputs.</p>

<div class="section" id="restrictions">
<h2>Restrictions<a class="headerlink" href="#restrictions" title="Permalink to this headline">¶</a></h2>
<p>This fix 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>
