Good evening everyone,
I am working on a single phase laminar flow (spf) model on COMSOL 5.1 for which I need to impose pressure boundary conditions. I read in the manual that the pressure p0, defined at the boundary, may be either absolute or relative depending on the value of reference pressure pref, "defined at the physics interface level".
How do I know what is the pref of my model? How can I edit its value? I cannot find pref defined anywhere in the physics node (nor in the fluid properties or initial conditions).
Thank you very much in advance for your help.
Best,
SB
