Class
    Foam::functionObjects::populationBalanceSizeDistribution

Description
    Writes out the size distribution determined by a population balance model,
    either for the entire domain or a cell zone. Requires solver post-
    processing.

    The following function object specification for example returns the volume-
    based number density function:

    Example of function object specification:
    \verbatim
    numberDensity
    {
        type                populationBalanceSizeDistribution;
        libs                ("libmultiphaseEulerFoamFunctionObjects.so");
        writeControl        writeTime;
        populationBalance   bubbles;
        functionType        numberDensity;
        coordinateType      volume;
        setFormat           raw;
    }
    \endverbatim
