Hello Foamers,

i have a problem. I'm not able to calculate the fluid flow through a surface (inlet or outlet for example).

At my domain i have several inlets and outlets with different settings. ("pressureInlet", "inlet" and "fixedVelocityOutlet")
To see if paraView calculates right, i let it calulate the fluid flow at the "inlet"- and the "fixedVelocityOutlet"-patch. (one by one - not at same time). Because so i can compare the paraView result value for the fluid flow with the theoretical value which i set up through the magnitude of the surface area and the given velocity there (dV/dt=A*U). (they should be equal)

My procedure:
I clicked on "Filter" in the menu and selected "Extract Parts" by clicking on it. Then i chose my "inlet"-patch (for example) and clicked on "Accept". Now with "ExtractParts0" highlightened i clicked on "Generate a Glyph" and the velocity-vectors from this patch (surface) are shown. Last i clicked on "Integrate a Vectorfield" to yield the fluid flow through this surface. But now i get the problem. the calulated value does not match the theoretical value.

My questions are:
1)Did i anything (or all) wrong?
2)What are the units (dimension) of this value there? (my theor. fluid flow value was in [m³/h] - so i calculated it to [m³/s], cause foam uses [m] als length units (as i likely too)
In fact i expected a value arround 160000 m³/h and paraView showed me a value arround 120.000 [???]
3)Is the "." (dot) a sign for the 1000er value or the comma for the value?

Thank you in advance for your help.
