Re: [Steady RANS]Discontinuous velocity value near a window

On the other hand, when I set pressure value (Pa) value at three windows, velocity and pressure are following,

.

Therefore, I am wondering why pressur range is too different each other even though velocity magnitude is not so different in each cases.
Therefore, I want to know what cause this difference.


Looking at the field, because pressure range is around 101324 by giving Cp value, pressure value is more natural than the case of pressure value (Pa)?

Hello,

Let me check the old question becasue I cannot solve the problem that non-physical flow appered near the window.
Is it OK to impose "Imoposed P Outlet" for all windows?
I am worry that there is a possibility that "Imoposed P Outlet" is only available to outlet condition, so I should give another condition for one window.

Hello,

I think it is possible, but did not check on any example.

If an outlet becomes an inlet due to pressure differences, the problem is the inlet values of the other variables will not be defined. So free inlet/outlet is probably better, as it is designed for this.

Best regards,
