Hi,Guys,

I am a little confused about the atmophere pressure value in Lammps with real units. The mannual saying:

  • pressure = atmospheres (real units)

    Does this mean the standard sea level air pressure value is 1 atm or 101325 Pa or other with real units in Lammps?

    The pressure is absolute pressure or relative pressure? Thanks in advance.

    Have a good day!

    Bests,

what it says is that any pressure output is done in
the (non-SI) unit of atmospheres (atm). so the pressure
at standard conditions would be 1.

   The pressure is absolute pressure or relative pressure? Thanks in
advance.

what is a "relative pressure"?. there is just *the* pressure.
