Dear All,
I’m trying to understand the thermal conductivity calculation explained in the readme file of the KAPPA example.
For example the in.ehex explanation (Although the question can be applied to all the other files as well).
(3) in.ehex
dQ = (100*100) / 100 / 18.82^2 / 2
100*100 = 100 (time in tau) * 100 (energy delta specified in fix heat)
100 = 20,000 steps at 0.005 tau timestep = run time in tau
xy box area = 18.82^2
divide by 2 since energy flux goes in 2 directions due to periodic z
dTemp = 0.770 from log file for average Temp difference between 2 regions
dZ = 18.82
Kappa = 3.45
When calculating dQ what is the 100 time in tau referring to? it’s not the run time because it’s mentioned later. So what is it? and where is it specified in the in.ehex file?
I attached the in.ehex file and the readme file for later reference.
Best regards,
Yunes Salman
