[gmx-users] liquid?

[nicolas Dinter]

Dear Gromacs users,

I have done a NPT simulation for the Benzene (120 molecules/ 1bar/ 300K). I
optain good values for box size and density but when I have a look in the
ngmx animation, benzene seems to be solid! Moreover, from this point, if I
increase the Temperature and the pressure to 673K and 150 bar there is not
change for the box-size and molecules just vibrate.
If there somebody who can explain me why?
thanks.
