Examples

.. code-block:: LAMMPS

   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 <PDF/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 the :doc:`Howto output <Howto_output>` page for an overview of
LAMMPS output options.

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

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

This compute is part of the MACHDYN package.  It is only enabled if
LAMMPS was built with that package.  See the :doc:`Build package <Build_package>` page for more info.

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