[Description:]

|
|
|
|
2016-01-30 01:09:55 +08:00
|
|
|
Define a computation that calculates the rate of the strain tensor for
|
|
|
|
|
particles interacting via the Total-Lagrangian SPH pair style.

[Output info:]
|
|
|
|
|
|
2016-01-30 01:09:55 +08:00
|
|
|
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.
|
2015-08-05 08:29:31 +08:00
|
|
|
|
|
|
|
|
The values will be given in "units"_units.html of one over time.
|
|
|
|
|
|
2016-01-30 01:09:55 +08:00
|
|
|
The per-particle vector has 6 entries, corresponding to the xx, yy,
|
|
|
|
|
zz, xy, xz, yz components of the symmetric strain rate tensor.

[Restrictions:]
|
|
|
|
|
|
|
|
|
|
This compute is part of the USER-SMD package. It is only enabled if
|
2016-01-30 01:09:55 +08:00
|
|
|
LAMMPS was built with that package. See the "Making
|
|
|
|
|
LAMMPS"_Section_start.html#start_3 section for more info.

|
|
|
|
2016-01-30 01:09:55 +08:00
|
|
|
This quantity will be computed only for particles which interact with
|
|
|
|
|
Total-Lagrangian SPH pair style.
