Class
    Foam::layerAverage
 
Description
    Generates plots of fields averaged over the layers in the mesh
 
    Example of function object specification:
    \verbatim
    layerAverage1
    {
        type            layerAverage;
        libs            ("libfieldFunctionObjects.so");
 
        writeControl    writeTime;
 
        setFormat       raw;
 
        patches         (bottom);
        zones           (quarterPlane threeQuartersPlane);
 
        axis            y;
 
        symmetric       true;
 
        fields          (pMean pPrime2Mean UMean UPrime2Mean k);
    }
    \endverbatim
