Hi, everyone. I am puzzled what is the physical unit of VTK_P_G?
What’s more, in BC, the gas pressure of outlet is 101325 Pa by default. In paraview, the average pressure of the surface 0.25 mm below the outlet is this:

Does this mean that the output pressure is gauge pressure？

If you define a non-zero value of P_ref with incompressible flow, you will use gauge pressure.

Thanks a lot! :grinning:
