Description
|
|
"""""""""""
|
|
|
|
Define a computation that returns the number of neighbor particles
|
|
inside of the smoothing kernel radius for particles interacting via
|
|
the updated 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 returns a per-particle vector, which can be accessed by
|
|
any command that uses per-particle values from a compute as input.
|
|
See :ref:`Section_howto 15 <howto_15>` for an overview of
|
|
LAMMPS output options.
|
|
|
|
The per-particle values will be given dimentionless, 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_2>` section for more info. This compute
|
|
can only be used for particles which interact with the updated
|
|
Lagrangian SPH pair style.
