[Examples:]
|

pair_style agni
|

pair_coeff * * Al.agni Al
|
||||
|
||||
[Description:]
|
||||
|
||||
Style {agni} style computes the manybody vectorial force components for
|
||||
an atom as
|
||||
|
||||
:c,image(Eqs/pair_agni.jpg)
|
||||
|
||||
{u} labels the individual components, i.e. x, y or z, and {V} is the
|
||||
corresponding atomic fingerprint. {d} is the Euclidean distance between
|
||||
any two atomic fingerprints. A total of N_t reference atomic
|
||||
environments are considered to construct the force field file. {alpha_t}
|
||||
and {l} are the weight coefficients and length scale parameter of the
|
||||
non-linear regression model.
|
||||
|
||||
The method implements the recently proposed machine learning access to
|
||||
atomic forces as discussed extensively in the following publications -
|
||||
"(Botu1)"_#Botu2015adaptive and "(Botu2)"_#Botu2015learning. The premise
|
||||
of the method is to map the atomic enviornment numerically into a
|
||||
fingerprint, and use machine learning methods to create a mapping to the
|
||||
vectorial atomic forces.
|
||||
|
||||
Only a single pair_coeff command is used with the {agni} style which
|
||||
specifies an AGNI potential file containing the parameters of the
|
||||
force field for the needed elements. These are mapped to LAMMPS atom
|
||||
types by specifying N additional arguments after the filename in the
|
||||
pair_coeff command, where N is the number of LAMMPS atom types:
|
||||
|
||||
filename
|
||||
N element names = mapping of AGNI elements to atom types :ul
|
||||
|
||||
See the "pair_coeff"_pair_coeff.html doc page for alternate ways
|
||||
to specify the path for the force field file.
|
||||
|
||||
An AGNI force field is fully specified by the filename which contains the
|
||||
parameters of the force field, i.e., the reference training environments
|
||||
used to construct the machine learning force field. Example force field
|
||||
and input files are provided in the examples/USER/misc/agni directory.
|
||||
|
||||
:line
|
||||
|
||||
Styles with {omp} suffix is functionally the same as the corresponding
|
||||
style without the suffix. They have been optimized to run faster, depending
|
||||
on your available hardware, as discussed in "Section 5"_Section_accelerate.html
|
||||
of the manual. The accelerated style takes the same arguments and
|
||||
should produce the same results, except for round-off and precision
|
||||
issues.
|
||||
|
||||
The accelerated style is part of the USER-OMP. They are only enabled if
|
||||
LAMMPS was built with those packages. See the "Making
|
||||
LAMMPS"_Section_start.html#start_3 section for more info.
|
||||
|
||||
You can specify the accelerated style explicitly in your input script
|
||||
by including their suffix, or you can use the "-suffix command-line
|
||||
switch"_Section_start.html#start_7 when you invoke LAMMPS, or you can
|
||||
use the "suffix"_suffix.html command in your input script.
|
||||
|
||||
See "Section 5"_Section_accelerate.html of the manual for
|
||||
more instructions on how to use the accelerated styles effectively.

[Mixing, shift, table, tail correction, restart, rRESPA info]:
|
||||
|
||||
This pair style does not support the "pair_modify"_pair_modify.html
|
||||
shift, table, and tail options.
|
||||
|
||||
This pair style does not write its information to "binary restart
|
||||
files"_restart.html, since it is stored in potential files. Thus, you
|
||||
need to re-specify the pair_style and pair_coeff commands in an input
|
||||
script that reads a restart file.
|
||||
|
||||
This pair style can only be used via the {pair} keyword of the
|
||||
"run_style respa"_run_style.html command. It does not support the
|
||||
{inner}, {middle}, {outer} keywords.
|
||||
|
||||
:line
|
||||
|
||||
[Restrictions:]
|
||||
|
||||
Currently, only elemental systems are implemented. Also, the method only
|
||||
provides access to the forces and not energies or stresses. However, one
|
||||
can access the energy via thermodynamic integration of the forces as
|
||||
discussed in "(Botu3)"_#Botu2016construct. This pair style is part
|
||||
of the USER-MISC 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.
|
||||
|
||||
The AGNI force field files provided with LAMMPS (see the
|
||||
potentials directory) are parameterized for metal "units"_units.html.
|
||||
You can use the AGNI potential with any LAMMPS units, but you would need
|
||||
to create your own AGNI potential file with coefficients listed in the
|
||||
appropriate units if your simulation doesn't use "metal" units.
