Please visualize that result. Such a command would put solvent all around
your nanotube, so it could not have an infin
can I calculate box size after NVT so that I get density of 1 or
0.99
when using pressure coupling?

Hi,
The simplest explanation is that your box size is inappropriate for the
contents. If the box wants to change size but the nanotube is restrained to
fixed positions then you have an invalid model.

This is a very common post on previous mailing list however, I am still not
able to fix the problem of position restraints during NPT.
I have a carbon nanotube aligned to z-direction. I am trying to simulate
infinite nanotube using periodic conditions. It is common to use position
restraints for n
