compute smd/ulsph/strain command :h3
|
|
|
|
[Syntax:]
|
|
|
|
compute ID group-ID smd/ulsph/strain :pre
|
|
|
|
ID, group-ID are documented in "compute"_compute.html command
|
|
smd/ulsph/strain = style name of this compute command :ul
|
|
|
|
[Examples:]
|
|
|
|
compute 1 all smd/ulsph/strain :pre
|
|
|
|
[Description:]
|
|
|
|
Define a computation that outputs the logarithmic strain tensor. for
|
|
particles interacting via the updated Lagrangian SPH pair style.
|
|
|
|
See "this PDF guide"_USER/smd/SMD_LAMMPS_userguide.pdf to using Smooth
|
|
Mach Dynamics in LAMMPS.
|
|
|
|
[Output info:]
|
|
|
|
This compute calculates a per-particle tensor, which can be accessed
|
|
by any command that uses per-particle values from a compute as input.
|
|
See "Section_howto 15"_Section_howto.html#howto_15 for an overview of
|
|
LAMMPS output options.
|
|
|
|
The per-particle vector has 6 entries, corresponding to the xx, yy,
|
|
zz, xy, xz, yz components of the symmetric strain rate tensor.
|
|
|
|
The per-particle tensor values will be given dimensionless, see
|
|
"units"_units.html.
|
|
|
|
[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 compute
|
|
can only be used for particles which interact with the updated
|
|
Lagrangian SPH pair style.
