[lammps-users] Poisseuille flow (fix temp/rescale or temp/berendsen)

Hi, all!
I have a question about Poisseuille flow with Lammps.
I wants to analyse the flowrate and shearing stress between the wall and the water molecules. The temperature should be steady.
Should I use fix NVE with fix temp/rescale or fix temp/berendsen?
I’ve read the examples with lammps, it uses fix NVE with fix temp/rescale. I just wants to know the differences and which one is better for my issue?
Thanks a lot!


Berendsen is typically better than simple rescaling. You should
read section 4.16 of the doc pages about thermostats and removing
biases (flow velocity in this case).
