[lammps-users] Questions

Hello, As a lammps user, I have an urgent question to consult you: By employing the bead-spring model to simulate the polymer melts, then i will use the following two commands(according to the lammps manual):
fix 1 all npt 1.0 1.0 0.05 aniso 0 0 0 0 NULL NULL 0.05 drag 2.0
fix 2 all deform 1 z erate 0.0327
My question is that for the combination of these two commands to perform the deformation behavior in the z direction, the command “remap v” or " remap x" is needed or not, and why?(I am very perplexed about this)

Thanks a lot,
With my best wishes,
Looking forward to your reply

See the doc/Section_howto.html section on NEMD. If you're
not doing NEMD via SLLOD, then just use the default which
is remap x.
