I have two question about thermal conductivity :
for kappa computing : how to compute or extract or get the cumulative delta energy for example in the script in.mp
here is what is written in ReadMe to explain how to get the value of kappa.
in.mp : dQ = 15087 / 100 / 18.82^2 / 2
15087 = cumulative delta energy, tallied by fix thermal/conductivity
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 = 1.16 from log file for average Temp difference between 2 regions
dZ = 18.82
Kappa = 3.45
could we compute directly kappa within the script with this method like th gk method ?
thanks in advance
