Hi All,

I tried using functionObject to calculate flow-rate through a sufrace. But I am getting following error ,

keyword sourceName is undefined in dictionary "/home/manoj/trial/vent/system/controlDict.functions.new_plane"

functions
{


    new_plane
    {
        type            faceSource;
        functionObjectLibs ("libfieldFunctionObjects.so");
        enabled         true;
        outputControl   outputTime;
        log             true;
        valueOutput     true;
        source          sampledSurface;

        sampledSurfaceDict
        {
         type        sampledTriSurfaceMesh;
         surface     opening.stl;
         source      cells;  // What to sample: cells (nearest cell)
                                    // insideCells (only triangles inside cell)
                                    // boundaryFaces (nearest boundary face)
         interpolate true;
        }

        operation       areaAverage;

        fields
        (
            U
        );
    }
}

I get the same error, when I use packaged function objects

functions
{
  #include "volFlowRateSurface"

}

Please help.

Regards,

Manoj

Similar error as above for v3.0. Was working fine in 2.4.x
Any help?

Hi,
I had the same error when passing from version 2.3 to 2.4.
You just have to add the line
sourceName MySourceName
in your functions in system/controlDict.
There are some examples in the tutorials.
Best,
Mat
