the dimensions doesn't change

hi,

I have make a configuration like this

OOOOOOO
OOOOOOO

Please explain what you do when you “change the dimensions” in LAMMPS

with the commands you invoke. Have you looked at the dump file

of atoms to see if the issue is with LAMMPS or with how VMD is interpreting

the output?

Dear Steve,

No I think it is the lammps problem. Bcoz I fixed the part I didnt see and pull the side i see which The molecules move as if they are not fixed at all.

I come to this result that the molecules i cant see actually doesnt exist.

By dimensions I mean for example the length of cu rve first was 5A then I changed it to 15A. But it is still 5A.

I will send the file soon. Now im from mobile
