<div class="section" id="description">
<h2>Description</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>
<p><strong>Restart, fix_modify, output, run start/stop, minimize info:</strong></p>
<p>Currently, no part of USER-SMD supports restarting nor minimization. This fix has no outputs.</p>
</div>
<div class="section" id="restrictions">
<h2>Restrictions</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 class="std std-ref">Making LAMMPS</span></a>
section for more info.</p>
