[Description:]
|
||||
|
||||
The {cg/cmm} angle style is a combination of the harmonic angle potential,
|
||||
|
||||
:c,image(Eqs/angle_harmonic.jpg)
|
||||
|
||||
where theta0 is the equilibrium value of the angle and K a prefactor,
|
||||
with the {repulsive} part of the non-bonded {cg/cmm} pair style
|
||||
between the atoms 1 and 3. This angle potential is intended for
|
||||
coarse grained MD simulations with the CMM parametrization using the
|
||||
"pair_style cg/cmm"_pair_cmm.html. Relative to the pair_style
|
||||
{cg/cmm}, however, the energy is shifted by {epsilon}, to avoid sudden
|
||||
jumps. Note that the usual 1/2 factor is included in K.
|
||||
|
||||
The following coefficients must be defined for each angle type via the
|
||||
"angle_coeff"_angle_coeff.html command as in the example above. As
|
||||
with other CMM coarse grained parameters, they cannot be set in the
|
||||
data file, but can be restored from restarts via the
|
||||
"read_restart"_read_restart.html command:
|
||||
|
||||
K (energy/radian^2)
|
||||
theta0 (degrees)
|
||||
cg_type (string, one of lj9_6, lj12_4, lj12_6)
|
||||
epsilon (energy units)
|
||||
sigma (distance units) :ul
|
||||
|
||||
Theta0 is specified in degrees, but LAMMPS converts it to radians
|
||||
internally; hence the units of K are in energy/radian^2.
|
||||
|
||||
[Restrictions:]
|
||||
|
||||
This angle style can only be used if LAMMPS was built with the
|
||||
USER-CG-CMM package. See the "Making

LAMMPS"_Section_start.html#start_3 section for more info on packages.

|

|

where C is an energy-conversion constant, Qi and Qj are the charges on
|
||||
the 2 atoms, and epsilon is the dielectric constant which can be set
|
||||
by the "dielectric"_dielectric.html command. If one cutoff is
|
||||
specified in the pair_style command, it is used for both the LJ and
|
||||
Coulombic terms. If two cutoffs are specified, they are used as
|
||||
cutoffs for the LJ and Coulombic terms respectively.
|
||||
|
||||
This style also contains an additional exp() damping factor
|
||||
to the Coulombic term, given by
|
||||
|
||||
:c,image(Eqs/pair_debye.jpg)
|
||||
|
||||
where kappa is the Debye length (kappa=0.0 is the unscreened coulomb).
|
||||
This potential is another way to mimic the screening effect of a polar
|
||||
solvent.
|
||||
|
||||
Style {cg/cmm/coul/long} computes the same Coulombic interactions as
|
||||
style {cg/cmm/coul/cut} except that an additional damping factor is
|
||||
applied to the Coulombic term so it can be used in conjunction with
|
||||
the "kspace_style"_kspace_style.html command and its {ewald} or {pppm}
|
||||
option. The Coulombic cutoff specified for this style means that
|
||||
pairwise interactions within this distance are computed directly;
|
||||
interactions outside that distance are computed in reciprocal space.
|
||||
|
||||
The following coefficients must be defined for each pair of atoms
|
||||
types via the "pair_coeff"_pair_coeff.html command as in the examples
|
||||
above, or in the data file or restart files read by the
|
||||
"read_data"_read_data.html or "read_restart"_read_restart.html
|
||||
commands, or by mixing as described below:
|
||||
|
||||
cg_type (lj9_6, lj12_4, or lj12_6)
|
||||
epsilon (energy units)
|
||||
sigma (distance units)
|
||||
cutoff1 (distance units)
|
||||
cutoff2 (distance units) :ul
|
||||
|
||||
Note that sigma is defined in the LJ formula as the zero-crossing
|
||||
distance for the potential, not as the energy minimum. The prefactors
|
||||
are chosen so that the potential minimum is at -epsilon.
|
||||
|
||||
The latter 2 coefficients are optional. If not specified, the global
|
||||
LJ and Coulombic cutoffs specified in the pair_style command are used.
|
||||
If only one cutoff is specified, it is used as the cutoff for both LJ
|
||||
and Coulombic interactions for this type pair. If both coefficients
|
||||
are specified, they are used as the LJ and Coulombic cutoffs for this
|
||||
type pair.
|
||||
|
||||
For {cg/cmm/coul/long} only the LJ cutoff can be specified since a
|
||||
Coulombic cutoff cannot be specified for an individual I,J type pair.
|
||||
All type pairs use the same global Coulombic cutoff specified in the
|
||||
pair_style command.
|
||||

|
||||
|
||||
Styles with a {cuda}, {gpu}, or {opt} suffix are 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 "this section"_Section_accelerate.html of the manual.
|
||||
The accelerated styles take the same arguments and should produce the
|
||||
same results, except for round-off and precision issues.
|
||||
|
||||
These accelerated styles are part of the USER-CUDA, GPU, and OPT
|
||||
packages respectively. 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 styles explicitly in your input script
|
||||
by including their suffix, or you can use the "-suffix command-line
|
||||
switch"_Section_start.html#start_6 when you invoke LAMMPS, or you can
|
||||
use the "suffix"_suffix.html command in your input script.
|
||||
|
||||
See "this section"_Section_accelerate.html of the manual for more
|
||||
instructions on how to use the accelerated styles effectively.

[Mixing, shift, table, tail correction, restart, and rRESPA info]:
|
||||
|
||||
For atom type pairs I,J and I != J, the epsilon and sigma coefficients
|
||||
and cutoff distance for all of the cg/cmm pair styles {cannot} be mixed,
|
||||
since different pairs may have different exponents. So all parameters
|
||||
for all pairs have to be specified explicitly through the "pair_coeff"
|
||||
command. Defining then in a data file is also not supported, due to
|
||||
limitations of that file format.
|
||||
|
||||
All of the cg/cmm pair styles support the
|
||||
"pair_modify"_pair_modify.html shift option for the energy of the
|
||||
Lennard-Jones portion of the pair interaction.
|
||||
|
||||
The {cg/cmm/coul/long} pair styles support the
|
||||
"pair_modify"_pair_modify.html table option since they can tabulate
|
||||
the short-range portion of the long-range Coulombic interaction.
|
||||
|
||||
All of the cg/cmm pair styles write their information to "binary
|
||||
restart files"_restart.html, so pair_style and pair_coeff commands do
|
||||
not need to be specified in an input script that reads a restart file.
|
||||
|
||||
The cg/cmm, cg/cmm/coul/cut and lj/cut/coul/long pair styles support
|
||||
the use of the {inner}, {middle}, and {outer} keywords of the "run_style
|
||||
respa"_run_style.html command, meaning the pairwise forces can be
|
||||
partitioned by distance at different levels of the rRESPA hierarchy.
|
||||
See the "run_style"_run_style.html command for details.

[Restrictions:]
|
||||
|
||||
All of the cg/cmm pair styles are part of the USER-CG-CMM package.
|
||||
The {cg/cmm/coul/long} style also requires the KSPACE package to be
|
||||
built (which is enabled by default). They are only enabled if LAMMPS
|
||||
was built with that package. See the "Making
|
||||
LAMMPS"_Section_start.html#start_3 section for more info.
