Another option for thermalizing the Drude model is to use the
temperature-grouped Nose-Hoover (TGNH) thermostat proposed by :ref:`(Son) <TGNH-SON>`.
This is implemented as :doc:`fix tgnvt/drude <fix_tgnh_drude>` and :doc:`fix tgnpt/drude <fix_tgnh_drude>`.
It separates the kinetic energy into three contributions:
the molecular center of mass (COM) motion, the motion of atoms or atom-Drude pairs relative to molecular COMs,
and the relative motion of atom-Drude pairs.
An independent Nose-Hoover chain is applied to each type of motion.
When TGNH is used, the temperatures of molecular, atomic and Drude motion can be printed out with :doc:`thermo_style` command.

Description
"""""""""""
These commands are variants of the Nose-Hoover fix styles :doc:`fix nvt
<fix_nh>` and :doc:`fix npt <fix_nh>` for thermalized Drude polarizable
models. They apply temperature-grouped Nose-Hoover thermostat (TGNH)
proposed by :ref:`(Son) <tgnh-Son>`. When there are fast vibrational
modes with frequencies close to Drude oscillators (e.g. double bonds or
out-of-plane torsions), this thermostat can provide better kinetic
energy equipartitioning.
The difference between TGNH and the original Nose-Hoover thermostat is that,
TGNH separates the kinetic energy of the group into three contributions:
molecular center of mass (COM) motion,
motion of COM of atom-Drude pairs or non-polarizable atoms relative to molecular COM,
and relative motion of atom-Drude pairs.
An independent Nose-Hoover chain is applied to each type of motion.
The temperatures for these three types of motion are denoted as
molecular translational temperature (:math:`T_\mathrm{M}`), real atomic temperature (:math:`T_\mathrm{R}`) and Drude temperature (:math:`T_\mathrm{D}`),
which are defined in terms of their associated degrees of freedom (DOF):
.. math::
T_\mathrm{M}=\frac{\Sigma_{i}^{N_\mathrm{mol}} M_i V_i^2}{3 \left ( N_\mathrm{mol} - \frac{N_\mathrm{mol}}{N_\mathrm{mol,sys}} \right ) k_\mathrm{B}}
.. math::
T_\mathrm{R}=\frac{\Sigma_{i}^{N_\mathrm{real}} m_i (v_i-v_{M,i})^2}{(N_\mathrm{DOF} - 3 N_\mathrm{mol} + 3 \frac{N_\mathrm{mol}}{N_\mathrm{mol,sys}} - 3 N_\mathrm{drude}) k_\mathrm{B}}
.. math::
T_\mathrm{D}=\frac{\Sigma_{i}^{N_\mathrm{drude}} m_i^{\prime} v_i^{\prime 2}}{3 N_\mathrm{drude} k_\mathrm{B}}
Here :math:`N_\mathrm{mol}` and :math:`N_\mathrm{mol,sys}` are the numbers of molecules in the group and in the whole system, respectively.
:math:`N_\mathrm{real}` is the number of atom-Drude pairs and non-polarizable atoms in the group.
:math:`N_\mathrm{drude}` is the number of Drude particles in the group.
:math:`N_\mathrm{DOF}` is the DOF of the group.
:math:`M_i` and :math:`V_i` are the mass and the COM velocity of the i-th molecule.
:math:`m_i` is the mass of the i-th atom-Drude pair or non-polarizable atom.
:math:`v_i` is the velocity of COM of i-th atom-Drude pair or non-polarizable atom.
:math:`v_{M,i}` is the COM velocity of the molecule the i-th atom-Drude pair or non-polarizable atom belongs to.
:math:`m_i^\prime` and :math:`v_i^\prime` are the reduced mass and the relative velocity of the i-th atom-Drude pair.
.. note::
These fixes require that each atom knows whether it is a Drude particle or
not. You must therefore use the :doc:`fix drude <fix_drude>` command to
specify the Drude status of each atom type.
Because the TGNH thermostat thermostats the molecular COM motion,
all atoms belonging to the same molecule must be in the same group.
That is, these fixes can not be applied to a subset of a molecule.
For this fix to act correctly, ghost atoms need to know their velocity.
You must use the :doc:`comm_modify <comm_modify>` command to enable this.
These fixes assume that the translational DOF of the whole system is removed.
It is therefore recommended to invoke :doc:`fix momentum <fix_momentum>` command so that the :math:`T_\mathrm{M}` is calculated correctly.
----------
The thermostat parameters are specified using the *temp* keyword.
The thermostat is applied to only the translational DOF
for the particles. The translational DOF can also have
a bias velocity removed before thermostatting takes place; see the
description below. The desired temperature for molecular and real atomic motion is a
ramped value during the run from *Tstart* to *Tstop*\ . The *Tdamp*
parameter is specified in time units and determines how rapidly the
temperature is relaxed. For example, a value of 10.0 means to relax
the temperature in a timespan of (roughly) 10 time units (e.g. :math:`\tau`
or fs or ps - see the :doc:`units <units>` command).
The parameter *Tdrude* is the desired temperature for Drude motion at each timestep.
Similar to *Tdamp*, the *Tdamp_drude* parameter determines the relaxation speed for Drude motion.
Fix group are the only ones whose velocities and positions are updated
by the velocity/position update portion of the integration.
Other thermostat-related keywords are *tchain*\ and *tloop*\ ,
which are detailed in :doc:`fix nvt <fix_nh>`.
.. note::
A Nose-Hoover thermostat will not work well for arbitrary values
of *Tdamp*\ . If *Tdamp* is too small, the temperature can fluctuate
wildly; if it is too large, the temperature will take a very long time
to equilibrate. A good choice for many models is a *Tdamp* of around
100 timesteps. A smaller *Tdamp_drude* value would be required
to maintain Drude motion at low temperature.
.. code-block:: LAMMPS
fix 1 all nvt temp 300.0 300.0 $(100.0*dt) 1.0 $(20.0*dt)
----------
The barostat parameters for fix style *tgnpt/drude* is specified
using one or more of the *iso*\ , *aniso*\ , *tri*\ , *x*\ , *y*\ , *z*\ , *xy*\ ,
*xz*\ , *yz*\ , and *couple* keywords. These keywords give you the
ability to specify all 6 components of an external stress tensor, and
to couple various of these components together so that the dimensions
they represent are varied together during a constant-pressure
simulation. Other barostat-related keywords are *pchain*\ , *mtk*\ , *ploop*\ ,
*nreset*\ , *scalexy*\ , *scaleyz*\ , *scalexz*\ , *flip*\ and *fixedpoint*.
The meaning of barostat parameters are detailed in :doc:`fix npt <fix_nh>`.
Regardless of what atoms are in the fix group (the only atoms which
are time integrated), a global pressure or stress tensor is computed
for all atoms. Similarly, when the size of the simulation box is
changed, all atoms are re-scaled to new positions.
.. note::
Unlike the :doc:`fix temp/berendsen <fix_temp_berendsen>` command
which performs thermostatting but NO time integration, these fixes
perform thermostatting/barostatting AND time integration. Thus you
should not use any other time integration fix, such as :doc:`fix nve <fix_nve>` on atoms to which this fix is applied.
Likewise, these fixes should not be used on atoms that also
have their temperature controlled by another fix - e.g. by :doc:`fix langevin/drude <fix_langevin_drude>` command.
See the :doc:`Howto thermostat <Howto_thermostat>` and :doc:`Howto barostat <Howto_barostat>` doc pages for a discussion of different
ways to compute temperature and perform thermostatting and
barostatting.
----------
Like other fixes that perform thermostatting, these fixes can
be used with :doc:`compute commands <compute>` that calculate a
temperature after removing a "bias" from the atom velocities.
This is not done by default, but only if the :doc:`fix_modify <fix_modify>` command
is used to assign a temperature compute to this fix that includes such
a bias term. See the doc pages for individual :doc:`compute commands <compute>` to determine which ones include a bias. In
this case, the thermostat works in the following manner: the current
temperature is calculated taking the bias into account, bias is
removed from each atom, thermostatting is performed on the remaining
thermal DOF, and the bias is added back in.
.. note::
However, not all temperature compute commands are valid to be used with these fixes.
Precisely, only temperature compute that does not modify the DOF of the group can be used.
E.g. :doc:`compute temp/ramp <compute_temp_ramp>` and :doc:`compute viscosity/cos <compute_viscosity_cos>`
compute the kinetic energy after remove a velocity gradient without affecting the DOF of the group,
then they can be invoked in this way.
In contrast, :doc:`compute temp/partial <compute_temp_partial>` may remove the DOF at one or more dimensions,
therefore it cannot be used with these fixes.
----------
Restart, fix_modify, output, run start/stop, minimize info
"""""""""""""""""""""""""""""""""""""""""""""""""""""""""""
These fixes writes the state of all the thermostat and barostat
variables to :doc:`binary restart files <restart>`. See the
:doc:`read_restart <read_restart>` command for info on how to re-specify
a fix in an input script that reads a restart file, so that the
operation of the fix continues in an uninterrupted fashion.
The :doc:`fix_modify <fix_modify>` *temp* and *press* options are
supported by these fixes. You can use them to assign a
:doc:`compute <compute>` you have defined to this fix which will be used
in its thermostatting or barostatting procedure, as described above.
If you do this, note that the kinetic energy derived from the compute
temperature should be consistent with the virial term computed using
all atoms for the pressure. LAMMPS will warn you if you choose to
compute temperature on a subset of atoms.
.. note::
If both the *temp* and *press* keywords are used in a single
thermo_modify command (or in two separate commands), then the order in
which the keywords are specified is important. Note that a :doc:`pressure compute <compute_pressure>` defines its own temperature compute as
an argument when it is specified. The *temp* keyword will override
this (for the pressure compute being used by fix npt), but only if the
*temp* keyword comes after the *press* keyword. If the *temp* keyword
comes before the *press* keyword, then the new pressure compute
specified by the *press* keyword will be unaffected by the *temp*
setting.
The :doc:`fix_modify <fix_modify>` *energy* option is supported by these
fixes to add the energy change induced by Nose/Hoover thermostatting
and barostatting to the system's potential energy as part of
:doc:`thermodynamic output <thermo_style>`.
These fixes compute a global scalar and a global vector of quantities,
which can be accessed by various :doc:`output commands <Howto_output>`.
The scalar value calculated by these fixes is "extensive"; the vector
values are "intensive".
The scalar is the cumulative energy change due to the fix.
The vector stores the three temperatures :math:`T_\mathrm{M}`, :math:`T_\mathrm{R}` and :math:`T_\mathrm{D}`.
These fixes can ramp their external temperature and pressure over
multiple runs, using the *start* and *stop* keywords of the
:doc:`run <run>` command. See the :doc:`run <run>` command for details of
how to do this.
These fixes are not invoked during :doc:`energy minimization <minimize>`.
----------
Restrictions
""""""""""""
These fixes are only available when LAMMPS was built with the USER-DRUDE package.
These fixes cannot be used with dynamic groups as defined by the :doc:`group <group>` command.
These fixes cannot be used in 2D simulations.
*X*\ , *y*\ , *z* cannot be barostatted if the associated dimension is not
periodic. *Xy*\ , *xz*\ , and *yz* can only be barostatted if the
simulation domain is triclinic and the second dimension in the keyword

:doc:`read data <read_data>`, and :doc:`read_restart <read_restart>`
commands specify whether the simulation box is orthogonal or
non-orthogonal (triclinic) and explain the meaning of the xy,xz,yz
tilt factors.
For the *temp* keyword, the final *Tstop* cannot be 0.0 since it would
make the external T = 0.0 at some timestep during the simulation which
is not allowed in the Nose/Hoover formulation.
The *scaleyz yes*\ , *scalexz yes*\ , and *scalexy yes* options
can only be used if the second dimension in the keyword is periodic,

/* ERROR/WARNING messages:
E: Illegal ... command
Self-explanatory. Check the input script syntax and compare to the
documentation for the command. You can use -echo screen as a
command-line option when running LAMMPS to see the offending line.
E: Target temperature for fix nvt/npt/nph cannot be 0.0
Self-explanatory.
E: Invalid fix nvt/npt/nph command for a 2d simulation
Cannot control z dimension in a 2d model.
E: Fix nvt/npt/nph dilate group ID does not exist
Self-explanatory.
E: Invalid fix nvt/npt/nph command pressure settings
If multiple dimensions are coupled, those dimensions must be
specified.
E: Cannot use fix nvt/npt/nph on a non-periodic dimension
When specifying a diagonal pressure component, the dimension must be
periodic.
E: Cannot use fix nvt/npt/nph on a 2nd non-periodic dimension
When specifying an off-diagonal pressure component, the 2nd of the two
dimensions must be periodic. E.g. if the xy component is specified,
then the y dimension must be periodic.
E: Cannot use fix nvt/npt/nph with yz scaling when z is non-periodic dimension
The 2nd dimension in the barostatted tilt factor must be periodic.
E: Cannot use fix nvt/npt/nph with xz scaling when z is non-periodic dimension
The 2nd dimension in the barostatted tilt factor must be periodic.
E: Cannot use fix nvt/npt/nph with xy scaling when y is non-periodic dimension
The 2nd dimension in the barostatted tilt factor must be periodic.
E: Cannot use fix nvt/npt/nph with both yz dynamics and yz scaling
Self-explanatory.
E: Cannot use fix nvt/npt/nph with both xz dynamics and xz scaling
Self-explanatory.
E: Cannot use fix nvt/npt/nph with both xy dynamics and xy scaling
Self-explanatory.
E: Can not specify Pxy/Pxz/Pyz in fix nvt/npt/nph with non-triclinic box
Only triclinic boxes can be used with off-diagonal pressure components.
See the region prism command for details.
E: Invalid fix nvt/npt/nph pressure settings
Settings for coupled dimensions must be the same.
E: Using update dipole flag requires atom style sphere
Self-explanatory.
E: Using update dipole flag requires atom attribute mu
Self-explanatory.
E: Fix nvt/npt/nph damping parameters must be > 0.0
Self-explanatory.
E: Cannot use fix npt and fix deform on same component of stress tensor
This would be changing the same box dimension twice.
E: Temperature ID for fix nvt/npt does not exist
Self-explanatory.
E: Pressure ID for fix npt/nph does not exist
Self-explanatory.
E: Non-numeric pressure - simulation unstable
UNDOCUMENTED
E: Fix npt/nph has tilted box too far in one step - periodic cell is too far from equilibrium state
Self-explanatory. The change in the box tilt is too extreme
on a short timescale.
E: Could not find fix_modify temperature ID
The compute ID for computing temperature does not exist.
E: Fix_modify temperature ID does not compute temperature
The compute ID assigned to the fix must compute temperature.
W: Temperature for fix modify is not for group all
The temperature compute is being used with a pressure calculation
which does operate on group all, so this may be inconsistent.
E: Pressure ID for fix modify does not exist
Self-explanatory.
E: Could not find fix_modify pressure ID
The compute ID for computing pressure does not exist.
E: Fix_modify pressure ID does not compute pressure
The compute ID assigned to the fix must compute pressure.
U: The dlm flag must be used with update dipole
Self-explanatory.
