Hello, 

I'm running a 2D simulation of a tube with 2 faces, each having a diameter of 15 mm. 

On one side, there's a volume flow rate of 6x10^-4 m^3/s. 

On the other side, there's a pressure outlet of 10 Pa. 

But when I calculate the area, the order of significantly differnt from waht I expected. The are should be 1.5x10^-4 m^2, but the result from ANSYS is 1.5x10^-2 m^2. Can anyone explain why there’s such a large discrepancy?

Additionally, when I applied a scale factor to correct the area, the outlet pressure automatically changed. Instead of remaining at 10 Pa, it increased to 24 Pa. Why did this happen?

Thanks
