When you say "after many timesteps" do you mean averaging over many
timesteps or just waiting for many timesteps for the system to
equilibrate? The instantaneous pressures and velocities certainly
won't be equal due to random fluctuations--you are probably going to
have to use fix ave/time or fix ave/spatial to get good results.
