with a "thermostatting fix"_Section_howto.html#howto_13, the energy
added to the hot region should equal the energy subtracted from the
cold region and be proportional to the heat flux moving between the
regions. See the paper by "Ikeshoji and Hafskjold"_#Ikeshoji for
details of this idea. Note that thermostatting fixes such as "fix
nvt"_fix_nh.html, "fix langevin"_fix_langevin.html, and "fix

and "Wirnsberger et al"_#howto-Wirnsberger for details of this idea.
Note that thermostatting fixes such as "fix nvt"_fix_nh.html, "fix
langevin"_fix_langevin.html, and "fix
temp/rescale"_fix_temp_rescale.html store the cumulative energy they
add/subtract.
Alternatively, as a second method, the "fix heat"_fix_heat.html
command can used in place of thermostats on each of two regions to
add/subtract specified amounts of energy to both regions. In both
cases, the resulting temperatures of the two regions can be monitored
with the "compute temp/region" command and the temperature profile of
the intermediate region can be monitored with the "fix
ave/spatial"_fix_ave_spatial.html and "compute
Alternatively, as a second method, the "fix heat"_fix_heat.html or
