Heat flux between particles

Submitted by B45034 on Sat, 09/08/2018 - 19:18

hi there,
I found out that there are 2 command that can give the heat flux of the particles:
1. fix heat/gran/conduction command
2. compute pair/gran/local command
And i guess the unit of both heat flux is energy/time (J/second). and i guess both of them are conductive heat transfer between particles.
So, what is the different between them?

P.S. i tried some cases, the output of these two command are different, although both of them named HeatFlux.
thx.
