Detailed Description

This function object provides a 'face source' variant of the fieldValues function object. Given a list of user-specified fields and a selection of mesh (or general surface) faces, a number of operations can be performed, such as sums, averages and integrations.

For example, to calculate the volumetric or mass flux across a patch, apply the 'sum' operator to the flux field (typically phi)

Example of function object specification:

faceSource1
{
    type            faceSource;
    functionObjectLibs ("libfieldFunctionObjects.so");
    ...
    log             yes;
    valueOutput     true;
    surfaceFormat   none;
    source          faceZone;
    sourceName      f0;
    operation       sum;
    weightField     alpha1;
    fields
    (
        p
        phi
        U
    );
}

Function object usage

Property	Description	Required	Default value
`type`	type name: faceSource	yes
`log`	write data to standard output	no	no
`valueOutput`	write the output values	yes
`writeArea`	Write the area of the faceSource	no
`surfaceFormat`	output value format	no
`source`	face source: see below	yes
`sourceName`	name of face source if required	no
`operation`	operation to perform	yes
`weightField`	name of field to apply weighting	no
`orientedWeightField`	name of oriented field to apply weighting	no
`scaleFactor`	scale factor	no	1
`fields`	list of fields to operate on	yes
`orientedFields`	list of oriented fields to operate on	no

Where source is defined by

faceZone	:	requires a 'sourceName' entry to specify the faceZone
patch	:	requires a 'sourceName' entry to specify the patch
sampledSurface	:	requires a 'sampledSurfaceDict' sub-dictionary

The operation is one of:

none	:	no operation
sum	:	sum
sumMag	:	sum of component magnitudes
sumDirection	:	sum values which are positive in given direction
sumDirectionBalance	:	sum of balance of values in given direction
average	:	ensemble average
weightedAverage	:	weighted average
areaAverage	:	area weighted average
weightedAreaAverage	:	weighted area average
areaIntegrate	:	area integral
min	:	minimum
max	:	maximum
CoV	:	coefficient of variation: standard deviation/mean
areaNormalAverage	:	area weighted average in face normal direction
areaNormalIntegrate	:	area weighted integral in face normal directon

Note

The values reported by the areaNormalAverage and areaNormalIntegrate operations are written as the first component of a field with the same rank as the input field.
faces on empty patches get ignored
if the field is a volField the faceZone can only consist of boundary faces
the `oriented' entries relate to mesh-oriented fields, such as the flux, phi. These fields will be oriented according to the face normals.
using sampledSurfaces:
- not available for surface fields
- if interpolate=true they use interpolationCellPoint otherwise they use cell values
- each triangle in sampledSurface is logically only in one cell so interpolation will be wrong when triangles are larger than cells. This can only happen for sampling on a triSurfaceMesh
- take care when using isoSurfaces - these might have duplicate triangles and so integration might be wrong
