<H3>fix smd/integrate_tlsph command
</H3>
<P><B>Syntax:</B>
</P>
<PRE>fix ID group-ID smd/integrate_tlsph keyword values
</PRE>
<UL><LI>ID, group-ID are documented in <A HREF = "fix.html">fix</A> command
<LI>smd/integrate_tlsph = style name of this fix command
<LI>zero or more keyword/value pairs may be appended
</UL>
<LI>keyword = <I>limit_velocity</I>
<PRE> <I>limit_velocity</I> value = max_vel
max_vel = maximum allowed velocity
</PRE>
</UL>
<P><B>Examples:</B>
</P>
<PRE>fix 1 all smd/integrate_tlsph
fix 1 all smd/integrate_tlsph limit_velocity 1000
</PRE>
<P><B>Description:</B>
</P>
<P>The fix performs explicit time integration for particles which interact according with the Total-Lagrangian SPH pair style.
</P>
<P>See <A HREF = "USER/smd/SMD_LAMMPS_userguide.pdf">this PDF guide</A> to using Smooth Mach Dynamics in LAMMPS.
</P>
<P>The <I>limit_velocity</I> keyword will control the velocity, scaling the norm of
the velocity vector to max_vel in case it exceeds this velocity limit.
</P>
<P><B>Restart, fix_modify, output, run start/stop, minimize info:</B>
</P>
<P>Currently, no part of USER-SMD supports restarting nor minimization. This fix has no outputs.
</P>
<P><B>Restrictions:</B>
</P>
<P>This fix is part of the USER-SMD package. It is only enabled if
LAMMPS was built with that package. See the <A HREF = "Section_start.html#start_3">Making LAMMPS</A>
section for more info.
