Summary0002454: Example dictionary for fieldCoordinateSystemTransform functionObject does not work
DescriptionThe example Dictionary (postProcessingDict) for fieldCoordinateSystemTransform functionObject does not work. When I paste the fieldCoordinateSystemTransform1 dictionary into my controlDict I get the following error:

--> FOAM FATAL IO ERROR:
keyword origin is undefined in dictionary "/casePath/system/controlDict.functions.fieldCoordinateSystemTransform1"

file: /casePath/system/controlDict.functions.fieldCoordinateSystemTransform1 from line 64 to line 86.

    From function const Foam::entry& Foam::dictionary::lookupEntry(const Foam::word&, bool, bool) const
    in file db/dictionary/dictionary.C at line 441
Steps To ReproduceUse the example Dictionary for the functionObject and execute the function object.
TagscoordinateTransformation, functionObject

I've confirmed that this also occurs with OpenFOAM 4.x (commit e964d879e2) and OpenFOAM-dev (0ab1758b2f5).

Furthermore, the method "fieldCoordinateSystemTransform::read" is not re-reading the settings into the variable "coordSys_" and therefore it's only done in the constructor.

@Henry: I've attached the package "bug2454_4.x_v1.tar.gz", which contains the following files and respective proposed changes for OpenFOAM 4.x:

  - src/functionObjects/field/fieldCoordinateSystemTransform/fieldCoordinateSystemTransform.C

    - Constructor for 'coordSys_' now uses 'dict.subDict("coordinateSystem")' instead of just 'dict'.

    - I did not add this to the 'read' method because it would affect the results, i.e. the changing coordinates during a simulation would make the originally outputted fields inconsistent with the others after the change.


  - src/functionObjects/field/fieldCoordinateSystemTransform/fieldCoordinateSystemTransform.H

    - Updated the description to use "coordinateRotation".

  - src/functionObjects/field/fieldCoordinateSystemTransform/postProcessingDict

    - Same change as in the description.

  - src/meshTools/coordinateSystems/coordinateRotation/coordinateRotationNew.C

    - Removed the output line '"[default: axes ]"', given that this is not used at all as a default, nor is the name correct any more.


Sorry, I didn't provide the same changes for OpenFOAM-dev, since I didn't have time to test it, but it looked like it would be pretty much the same exact changes.


----

@olle: If you cannot upgrade to OpenFOAM 4.x after this patch is applied, you can use a workaround, by changing these lines:

        // Fields to be transformed - runTime modifiable
        fields
        (
            U
            UMean
            UPrime2Mean
        );

        coordinateSystem
        {
            origin (0.001 0 0);
            e1 (1 0.15 0);
            e3 (0 0 -1);
        }


To these:

        // Fields to be transformed - runTime modifiable
        fields
        (
            U
            UMean
            UPrime2Mean
        );

        origin (0 0 0);
        coordinateRotation
        {
            type axesRotation;
            e1 (1 0.15 0);
            e3 (0 0 -1);
        }
