fix meso command :h3

[Syntax:]

fix ID group-ID meso :pre

ID, group-ID are documented in "fix"_fix.html command
meso = style name of this fix command :ul

[Examples:]

fix 1 all meso :pre

[Description:]

Perform time integration to update position, velocity, internal energy
and local density for atoms in the group each timestep. This fix is
needed to time-integrate mesoscopic systems where particles carry
internal variables such as SPH or DPDE.

See "this PDF guide"_USER/sph/SPH_LAMMPS_userguide.pdf to using SPH in
LAMMPS.

[Restart, fix_modify, output, run start/stop, minimize info:]

No information about this fix is written to "binary restart
files"_restart.html.  None of the "fix_modify"_fix_modify.html options
are relevant to this fix.  No global or per-atom quantities are stored
by this fix for access by various "output
commands"_Section_howto.html#howto_15.  No parameter of this fix can
be used with the {start/stop} keywords of the "run"_run.html command.
This fix is not invoked during "energy minimization"_minimize.html.

[Restrictions:]

This fix is part of the USER-SPH package.  It is only enabled if
LAMMPS was built with that package.  See the "Making
LAMMPS"_Section_start.html#start_3 section for more info.
