compute smd/tlsph/strain command :h3

[Syntax:]

compute ID group-ID smd/tlsph/strain :pre

ID, group-ID are documented in "compute"_compute.html command
smd/tlsph/strain = style name of this compute command :ul

[Examples:]

compute 1 all smd/tlsph/strain :pre

[Description:]

Define a computation that calculates the Green-Lagrange strain tensor
for particles interacting via the Total-Lagrangian SPH pair style.

See "this PDF guide"_PDF/SMD_LAMMPS_userguide.pdf to using Smooth
Mach Dynamics in LAMMPS.

[Output info:]

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 "How-to discussions, section
6.15"_Section_howto.html#howto_15 for an overview of LAMMPS output
options.

The per-particle tensor values will be given dimensionless. See
"units"_units.html.

The per-particle vector has 6 entries, corresponding to the xx, yy,
zz, xy, xz, yz components of the symmetric strain tensor.

[Restrictions:]

This compute is part of the USER-SMD 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.

This quantity will be computed only for particles which interact with
the Total-Lagrangian SPH pair style.
