removed from each atom, thermostatting is performed on the remaining

[Description:]
|
||||
|
||||
Reset the temperature of a group of atoms by explicitly rescaling
|
||||
their velocities.
|
||||
|
||||
The rescaling is applied to the translational degrees of freedom
|
||||
for all particles, and the electronic radial degrees of freedom. The translational degrees of freedom can also have a bias velocity removed from them before thermostatting takes place; see the description below.
|
||||
|
||||
Rescaling is performed every N timesteps. The target temperature is a
|
||||
ramped value between the {Tstart} and {Tstop} temperatures at the
|
||||
beginning and end of the run.
|
||||
|
||||
Rescaling is only performed if the difference between the current and
|
||||
desired temperatures is greater than the {window} value. The amount
|
||||
of rescaling that is applied is a {fraction} (from 0.0 to 1.0) of the
|
||||
difference between the actual and desired temperature. E.g. if
|
||||
{fraction} = 1.0, the temperature is reset to exactly the desired
|
||||
value.
|
||||
|
||||
IMPORTANT NOTE: Unlike the "fix nvt/eff"_fix_nh.html command which
|
||||
performs Nose/Hoover thermostatting AND time integration, this fix
|
||||
does NOT perform time integration. It only modifies velocities to
|
||||
effect thermostatting. Thus you must use a separate time integration
|
||||
fix, like "fix nve/eff"_fix_nve_eff.html to actually update the positions of atoms using the modified velocities. Likewise, this fix should not
|
||||
normally be used on atoms that also have their temperature controlled
|
||||
by another fix - e.g. by "fix nvt/eff"_fix_nh.html or "fix
|
||||
langevin/eff"_fix_langevin_eff.html commands.
|
||||
|
||||
See "this howto section"_Section_howto.html#4_16 of the manual for a
|
||||
discussion of different ways to compute temperature and perform
|
||||
thermostatting.
|
||||
|
||||
This fix computes a temperature each timestep. To do this, the fix
|
||||
creates its own compute of style "temp", as if one of this command had
|
||||
been issued:
|
||||
|
||||
compute fix-ID_temp group-ID temp/eff :pre
|
||||
|
||||
See the "compute temp/eff"_compute_temp_eff.html for details. Note that the ID of the new compute is the fix-ID + underscore + "temp", and the
|
||||
group for the new compute is the same as the fix group.
|
||||
|
||||
Note that this is NOT the compute used by thermodynamic output (see
|
||||
the "thermo_style"_thermo_style.html command) with ID = {thermo_temp}.
|
||||
This means you can change the attributes of this fix's temperature
|
||||
(e.g. its degrees-of-freedom) via the
|
||||
"compute_modify"_compute_modify.html command or print this temperature
|
||||
during thermodynamic output via the "thermo_style
|
||||
custom"_thermo_style.html command using the appropriate compute-ID.
|
||||
It also means that changing attributes of {thermo_temp} will have no
|
||||
effect on this fix.
|
||||
|
||||
Like other fixes that perform thermostatting, this fix can be used
|
||||
with "compute commands"_compute.html that calculate a temperature
|
||||
after removing a "bias" from the atom velocities. E.g. removing the
|
||||
center-of-mass velocity from a group of atoms or only calculating
|
||||
temperature on the x-component of velocity or only calculating
|
||||
temperature for atoms in a geometric region. This is not done by
|
||||
default, but only if the "fix_modify"_fix_modify.html command is used
|
||||
to assign a temperature compute to this fix that includes such a bias
|
||||
term. See the doc pages for individual "compute
|
||||
commands"_compute.html 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 degrees of freedom, and the bias is added back in.
|
||||
|
||||
[Restart, fix_modify, output, run start/stop, minimize info:]
|
||||
|
||||
No information about this fix is written to "binary restart
|
||||
files"_restart.html.
|
||||
|
||||
The "fix_modify"_fix_modify.html {temp} option is supported by this
|
||||
fix. You can use it to assign a temperature "compute"_compute.html
|
||||
you have defined to this fix which will be used in its thermostatting
|
||||
procedure, as described above. For consistency, the group used by
|
||||
this fix and by the compute should be the same.
|
||||
|
||||
The "fix_modify"_fix_modify.html {energy} option is supported by this
|
||||
fix to add the energy change implied by a velocity rescaling to the
|
||||
system's potential energy as part of "thermodynamic
|
||||
output"_thermo_style.html.
|
||||
|
||||
This fix computes a global scalar which can be accessed by various
|
||||
"output commands"_Section_howto.html#4_15. The scalar is the
|
||||
cummulative energy change due to this fix. The scalar value
|
||||
calculated by this fix is "extensive".
|
||||
|
||||
This fix can ramp its target temperature over multiple runs, using the
|
||||
{start} and {stop} keywords of the "run"_run.html command. See the
|
||||
"run"_run.html command for details of how to do this.
|
||||
|
||||
This fix is not invoked during "energy minimization"_minimize.html.
|
||||
|
||||
[Restrictions:]
|
||||
|
||||
This fix is part of the "user-eff" package. It is only enabled if
|
||||
LAMMPS was built with that package. See the "Making
|
||||
LAMMPS"_Section_start.html#2_3 section for more info.

||||
