[lammps-users] Appropriate ensemble for FIX boundry

Dear LAMMPS users,
Hi…
I have a question? How can we relax our box when its boundary is “f p p”? I mean, which ensemble is appropriate? Because, NPT doesn’t work for this boundary and we have error!

Thanks in advance
Nili

You can use fix npt on just the periodic dimensions.
See the doc page.
