Hi, about surface goal. intake mass flow is 1.5 (positive) but outlets is negative. why? Why first outlet port is positive? And which port can let more air: -0.2 or -0.1 (kg/s)Thanks a lot
you will need to provide some more detail about your setup
if those are pressure openings, there is no guarantee that they are inlets or outlets
and note that positive and negative follow standard conventions for fluid in and out of the system
intake is 202650 (Pa) static pressure, and outlets is (101350) Pa environment pressure
Do a surface parameter and take a look at the velocity component normal to your surface, is the flow moving into or out of your domain?
