			.. index:: compute smd/rho

			compute smd/rho command
			=======================

			Syntax
			""""""

			.. parsed-literal::

			compute ID group-ID smd/rho

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

			Examples
			""""""""

			.. parsed-literal::

			compute 1 all smd/rho

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

			Define a computation that calculates the per-particle mass density.
			The mass density is the mass of a particle which is constant during
			the course of a simulation, divided by its volume, which can change
			due to mechanical deformation.

			See `this PDF guide <USER/smd/SMD_LAMMPS_userguide.pdf>`_ to use 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 will be in :doc:`units <units>` of mass over volume.

			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.
