Output info:
</B>
</P>
<P>
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

for an overview of
LAMMPS output options.
</P>
<P>
The per-particle values will be given dimentionless, see

Restrictions:
</B>
</P>
<P>
This compute is part of the USER-SMD package. It is only enabled if
LAMMPS was built with that package. See the
<A

"Section_start.html#start_2"
>
Making LAMMPS
</A>
section for more info. This compute can only be used for particles which interact with the updated Lagrangian SPH pair style.
