[lammps-users] fix thermal/conductivity

hello, all,

I want to know that in the 2D simulation, how does lammps define the cross section in the command “fix thermal/conductivity” which is used the Muller−Plathe algorithm?

thank you!

I don't think LAMMPS uses a x-section. It just tabulates
exchanged energy. It's up to you to divide by x-section area
or length to get a flux.
