Hello dear foamers,

I observe Ux (x component of velocity U) over a line during my 2d, transient analysis by this script within my controldict.

functions{

myLinefunction{
   type sets;
   libs ("libsampling.so");
   interpolationScheme 	cellPoint;
   setFormat raw;
   writeControl   timeStep;
   writeInterval  1;
   sets
   (
	data
	{
		type uniform;
		axis xyz;
		start (0.349493 -0.357075 0.0);
		end (0.349493 0.357075 0.0);
		nPoints 200;
	}
   );
   fields 	(U);
}

}

However, I don't want this. I want OpenFOAM to calculate automatically the Umean if it is possible. The sketch below demonstrates the thing I want.

Without modifying the code, you could average the entire U field using fieldAverage, to get a field `UMean'. Then as a post-processing step you can calculate UMeanx over this line by changing "U" in fields to "UMean".

Thank you. It worked flawlessly.
