compute smd/tlsph/num/neighs command
====================================

Syntax
""""""

.. parsed-literal::

   compute ID group-ID smd/tlsph/num/neighs

* ID, group-ID are documented in :doc:`compute <compute>` command
* smd/tlsph/num/neighs = style name of this compute command

Examples
""""""""

.. parsed-literal::

   compute 1 all smd/tlsph/num/neighs

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

Define a computation that calculates the number of particles inside of
the smoothing kernel radius for particles interacting via the
Total-Lagrangian SPH pair style.

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

**Output info:**

This compute calculates a per-particle vector, which can be accessed
by any command that uses per-particle values from a compute as input.
See :ref:`How-to discussions, section 6.15 <howto_15>` for
an overview of LAMMPS output options.

The per-particle values are dimensionless. See :doc:`units <units>`.

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


This compute 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.

This quantity will be computed only for particles which interact with
the Total-Lagrangian pair style.
