Dear Lammps users:

I am learning compute heat/flux command. There are two questions:

1: in the following equation, how does the unit of the right

side of equal sign equal that of left side of equal sign?

kappa (KCal/(mol fmsec Ang K)) = V/(k_B*(T^2)) x "thermo" output

frequency x timestep x Integral value

2: I use correlate.py to calculate the integral of the

autocorrelation, the command is correlate.py flux.log -c 3 -s 200,

when I change 200 to 1000 or something else, the result is different,

why? How can I get the accurate result?

Thank you very much in advance!
