My interpretation of Kenno's link to a wiki with the most fundamental
concepts of thermodynamics is his way of saying that
p V = n R T
with n being the number of molecules and V being volume. It's an ideal
gas state equation. Notice that n/V is your density.
In your molecular dynamics, n does not change, so, if you want to keep
the density constant, you need to run your simulation at constant
Do I get it right Kenno?
In the "NAMD TUTORIAL" pdf, section 1.7.1, find the part that talks
about the NVT esemble. The tutorial is a companion to a group of files
from a molecular dynamics course or workshop. You should be able to
find the example configuration file there.
I hope I am being useful.
