Hi

In the boiling model of a simple 2d geometry, I wanted to insert the saturation temperature of water in different pressures. Now, I was wondering whether it is the absolute pressure or gauge pressure?
As the pressure outlet boundary condition is the gauge pressure, I guess I should insert gauge pressure here too. i.e., in the attached photo, the pressure is not written right because it is absolute pressure. So, I should subtract 101325 from this value. Am I right?

Thanks

It's the thermodynamic pressure, which means absolute pressure. Unless there is a bug.

Thank you for your reply.
So, what about the pressure in the pressure outlet boundary condition? Why is it written gauge pressure? In fact, when I see a plot in the results which shows the pressure in the outlet section, I see that it is the same as the pressure inserted in the boundary condition though it was written gauge pressure.
