Summary0003384: surfaceFieldValue causes error at inlet patches
DescriptionIn the case tutorials/lagrangian/simpleReactingParcelFoam/verticalChannel I make an additional entry in controlDict/functions for the patch "inletSides".

    surfaceFieldValue2
    {
        type surfaceFieldValue;
        libs ("libfieldFunctionObjects.so");
        enabled yes;
        writeControl writeTime;
        log yes;
        writeFields no;
        regionType patch;
        name inletSides;
        operation weightedAverage;
        weightField phi;
        fields
        (
            T
            //p -> comes to an error
        );
    }

The result for the field "T" in postProcessing is as follows:

# Time weightedAverage(T)
0 -1.0787610941e+308
10 -1.7686424138e+308

For the field "p" I get an error at the run:

surfaceFieldValue surfaceFieldValue2 write:
    weightedAverage(inletSides) of T = -1.078761094e+308

The problem with this setup is that the weighting field phi is 0 on the inletSides patch at the start of the run; it is set on the first U BC update, so you will need to set

        executeAtStart no;

to avoid weighting by a 0 field.

I have added "executeAtStart no", but the error messages have remained the same.

 For me it starts fine with

        executeAtStart no;

however it fails on the first dump, I will investigate further.

Try this:

commit a5c33c5e18401fc369fc0d120e31d32641e378b6 (HEAD -> master, origin/master, origin/HEAD)

    functionObject::surfaceFieldValue: Added support for weighting with negative fields
    
    For example this allows the an inlet flux to be used to create a weighted
    average.

Just by looking at the commit, is the Info-output intentional (line 156)?

No, temporary diagnostics statement I put in for testing. I think the fix resolves the issue so I have removed the diagnostics.
