PostProcessing fails for wallHeatFlux: OF6

Hi,

Just an observation.

Using wallHeatFlux during postprocess doesn't work in OF6. I came across this bug here: https://bugs.openfoam.org/view.php?id=3055. I have exact same type of error. Although it says this should have been resolved in the 5th August patch (and I've the updated version), it still won't work for "wallHeatFlux". It has been reopened but no further update so far. I did not try any other functionObjects. Perhaps this is still to be resolved? My workaround was to do it in OF5 where it works perfectly fine.

Also, as a side note, this is a great functionality introduced (not sure if it existed prior to OF6, I just discovered it). Very user-friendly:
In controlDict:

Code:

functions

{

    libs            ("libfieldFunctionObjects.so");



    Ma

    {

        type            MachNo;

        executeControl  writeTime;

        writeControl    writeTime;

    }



    #includeFunc wallHeatFlux

}

Hi,

I got similar wallheatflux error as yours. There's problem in OF6 and OF1812. For me, I got 0 values in OF1812, and in OF6, I got this error:

However, for the same problem, OF3 and 5 are both working.

Can someone confirm this error?
