[gmx-users] Temparature and density

[csreddy at ncbs.res.in]

Hi all,
I have one small doubt regarding high temperature simulation. Because I am
simulating at high temperature,for instance at 498 K, the density is
different (0.828 gram/cc at 498 K) from 300 K.
I have generated a water box whose density is around 1 gram/cc.
My question is ...
 should I change the density from present value 1 gram/cc to 0.828 gram/cc
before I start simulation?
 or
Because I am using NPT ensemble will it automatically adjust to that
density? (because box size will increase under high temperature and
constant pressure therefore density will be decreased)

I am a bit confused and need your invaluable suggestion. Please let me know.

Best Regards
Chandu
