compute temp/region/eff command :h3

[Syntax:]

compute ID group-ID temp/region/eff region-ID :pre

ID, group-ID are documented in "compute"_compute.html command
temp/region/eff = style name of this compute command
region-ID = ID of region to use for choosing atoms :ul

[Examples:]

compute mine flow temp/region/eff boundary :pre

[Description:]

Define a computation that calculates the temperature of a group of
nuclei and electrons in the "electron force field"_pair_eff.html
model, within a geometric region using the electron force field.  A
compute of this style can be used by commands that compute a
temperature, e.g. "thermo_modify"_thermo_modify.html.

The operation of this compute is exactly like that described by the
"compute temp/region"_compute_temp_region.html command, except that
the formula for the temperature itself includes the radial electron
velocity contributions, as discussed by the "compute
temp/eff"_compute_temp_eff.html command.

[Output info:]

This compute calculates a global scalar (the temperature) and a global
vector of length 6 (KE tensor), which can be accessed by indices 1-6.
These values can be used by any command that uses global scalar or
vector values from a compute as input.  See "this
section"_Section_howto.html#howto_15 for an overview of LAMMPS output
options.

The scalar value calculated by this compute is "intensive".  The
vector values are "extensive".

The scalar value will be in temperature "units"_units.html.  The
vector values will be in energy "units"_units.html.

[Restrictions:]

This compute 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#start_3 section for more info.

temp/eff"_compute_temp_eff.html, "compute
pressure"_compute_pressure.html

[Default:] none
