Class
    Foam::timeActivatedFileUpdate
 
Group
    grpUtilitiesFunctionObjects
 
Description
    This function object performs a file copy/replacement once a specified
    time has been reached.
 
    Example usage to update the fvSolution dictionary at various times
    throughout the calculation:
    \verbatim
    fileUpdate1
    {
        type              timeActivatedFileUpdate;
        functionObjectLibs ("libutilityFunctionObjects.so");
        fileToUpdate      "$FOAM_CASE/system/fvSolution";
        timeVsFile
        (
            (-1 "$FOAM_CASE/system/fvSolution.0")
            (0.10 "$FOAM_CASE/system/fvSolution.10")
            (0.20 "$FOAM_CASE/system/fvSolution.20")
            (0.35 "$FOAM_CASE/system/fvSolution.35")
        );
        ...
    }
    \endverbatim
