Hello,
How can I check a field (like U or p) on a surface into my domain?
Is there a command like patchAverage or patchIntegrate for surfaces?

Thank in advance for any reply

Thank you very much santhosh!
I compiled it and it works fine.
I would like to check the U field onto a surface in my domain.
I wrote in my controlDict

functions
(
surface
{
type surfaces;
functionObjectLibs
(
"libsimpleFunctionObjects.so"
);
verbose true;
// outputControl outputTime;
outputControl timeStep;
outputInterval $writeInterval;
fields
(
U
p
);
checkSurface
(
constantPlane
{
type plane; // always triangulated
basePoint (0.0 -0.11 0.0);
normalVector (0 -1 0);
}
);
}
);

The solver creates a new directory "checkSurface" whit in the sub-directory for each $writeInterval.
The problem is these sub-directory are empty!
Where did I make mistake?

Thanks
