Pressure Force Output

Dear all

In my model, a fixed component is placed above the flow and never touch the flow.

But when I see the Pressure Force in the z-direction, its value is NOT zero.

(The *.prepin file is attached.)

Any help is appreciated.

There is NO flow around the component, So there is NO pressure acting on the component, So the output force should be ZERO. But it is NOT zero.

When you analyze the pressure around the component go to probe and scroll down to component 1: x pressure force and so on to check the different forces that is acting on the object.

Hi
Thanks for the attempt, but:

Check the z pressure force, NOT x.
