They are the same, but I did not realize you were trying to do a constant
pressure simulation. With ntt=0, that would correspond to an "NPE" ensemble,
which doesnt' make good sense. If you are doing constant pressure, you
would not expect the total energy (and hence the temp.) to be conserved.
(We should probably think about making the combination ntp=1 and ntt=0 not
allowed....)
