Class
    Foam::functionObjects::blendingFactor

Group
    grpUtilitiesFunctionObjects

Description
    This function object calculates and outputs the blendingFactor as used by
    the bended convection schemes.  The output is a volume field (cells) whose
    value is calculated via the maximum blending factor for any cell face.
