    execFlowFunctionObjects

Description
    Execute the set of functionObjects specified in the selected dictionary
    (which defaults to system/controlDict) for the selected set of times.
    Alternative dictionaries should be placed in the system/ directory.

    The flow (p-U) and optionally turbulence fields are available for the
    function objects to operate on allowing forces and other related properties
    to be calculated in addition to cutting planes etc.
