fix smd/integrate_tlsph command
===============================

Syntax
""""""

.. parsed-literal::

   fix ID group-ID smd/integrate_tlsph keyword values

* ID, group-ID are documented in :doc:`fix <fix>` command
* smd/integrate_tlsph = style name of this fix command
* zero or more keyword/value pairs may be appended

* keyword = *limit_velocity*
.. parsed-literal::

     *limit_velocity* value = max_vel
       max_vel = maximum allowed velocity



Examples
""""""""

.. parsed-literal::

   fix 1 all smd/integrate_tlsph
   fix 1 all smd/integrate_tlsph limit_velocity 1000

Description
"""""""""""

The fix performs explicit time integration for particles which interact according with the Total-Lagrangian SPH pair style.

See `this PDF guide <USER/smd/SMD_LAMMPS_userguide.pdf>`_ to using Smooth Mach Dynamics in LAMMPS.

The *limit_velocity* keyword will control the velocity, scaling the norm of
the velocity vector to max_vel in case it exceeds this velocity limit.

Restart, fix_modify, output, run start/stop, minimize info
""""""""""""""""""""""""""""""""""""""""""""""""""""""""""

Currently, no part of USER-SMD supports restarting nor minimization. This fix has no outputs.

Restrictions
""""""""""""


This fix is part of the USER-SMD package.  It is only enabled if
LAMMPS was built with that package. See the :ref:`Making LAMMPS <start_3>`
section for more info.
