One thing I have noticed in this case, the model is not taking -50 Pa static preesure that I am specfying in pre file at outlet, it is showing a value of around 0.2 bar at outlet when I looked in expression (areaAve(Pressure)@outlet). That is the reason solver increased the pressure at inlet and showing high density. Also when I see the contour at outlet for pressure it is showing uniform pressure of -50 Pa. Why the expression value of pressure not matching with what is specified in pre-file?
