This function object writes graphs of patch face values, area-averaged in
planes perpendicular to a given direction. It adaptively grades the
distribution of graph points to match the resolution of the mesh.
Example of function object specification:
patchCutLayerAverage1
{
type patchCutLayerAverage;
libs ("libpatchCutLayerAverageFunctionObject.so");
writeControl writeTime;
writeInterval 1;
patch lowerWall;
direction (1 0 0);
nPoints 100;
interpolate no;
fields (p U);
axis x;
setFormat raw;
}
A packaged function object is also included, which permits the following
syntax to be used, either with #includeFunc in the system/controlDict,
or with the -func option to foamPostProcess:
graphPatchCutLayerAverage
(
funcName=aerofoilLowerPressure,
patch=aerofoilLower,
direction=(0.15 -0.016 0),
nPoints=100,
p
)

patch <patchName>; // Patch on which to average values
