+compute meso/rho/atom command
+=============================
+
+Syntax
+""""""
+
+.. parsed-literal::
+
+   compute ID group-ID meso/rho/atom
+
+* ID, group-ID are documented in :doc:`compute <compute>` command
+* meso/rho/atom = style name of this compute command
+
+Examples
+""""""""
+
+.. parsed-literal::
+
+   compute 1 all meso/rho/atom
+
+Description
+"""""""""""
+
+Define a computation that calculates the per-atom mesoscopic density
+for each atom in a group.
+
+The mesoscopic density is the mass density of a mesoscopic particle,
+calculated by kernel function interpolation using "pair style
+sph/rhosum".
+
+See `this PDF guide <USER/sph/SPH_LAMMPS_userguide.pdf>`_ to using SPH in
+LAMMPS.
+
+The value of the mesoscopic density will be 0.0 for atoms not in the
+specified compute group.
+
+**Output info:**
+
+This compute calculates a per-atom vector, which can be accessed by
+any command that uses per-atom values from a compute as input.  See
+:ref:`Section_howto 15 <howto_15>` for an overview of
+LAMMPS output options.
+
+The per-atom vector values will be in mass/volume :doc:`units <units>`.
+
+Restrictions
+""""""""""""
+
+
+This compute is part of the USER-SPH package.  It is only enabled if
+LAMMPS was built with that package.  See the :ref:`Making LAMMPS <start_3>` section for more info.
