<P>
This compute calculates a per-particle vector of vectors (tensors), which can be
accessed by any command that uses per-particle values from a compute as input. See

</P>
<P>
The per-particle vector has 7 entries. The first six entries correspond to the xx, yy, zz, xy, xz and yz components
of the symmetric Cauchy stress tensor. The seventh entry is the second invariant of the stress tensor, i.e.,
the von Mises equivalent stress.

Restrictions:

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

section for more info.
</P>
<P>
This quantity will be computed only for particles which interact with the Total-Lagrangian SPH pair style.
