Class
    Foam::functionObjects::timeActivatedFileUpdate
 
Group
    grpUtilitiesFunctionObjects
 
Description
    Performs a file copy/replacement once a specified time has been reached.
 
Usage
    Example usage to update the fvSolution dictionary at various times
    throughout the calculation:
    \verbatim
    fileUpdate1
    {
        type              timeActivatedFileUpdate;
        libs              (utilityFunctionObjects);
        writeControl      timeStep;
        writeInterval     1;
        fileToUpdate      "<system>/fvSolution";
        timeVsFile
        (
            (-1   "<system>/fvSolution.0")
            (0.10 "<system>/fvSolution.10")
            (0.20 "<system>/fvSolution.20")
            (0.35 "<system>/fvSolution.35")
        );
        ...
    }
    \endverbatim
 
    Where the entries comprise:
    \table
        Property     | Description             | Required    | Default value
        type         | Type name: timeActivatedFileUpdate | yes |
        fileToUpdate | Name of file to update  | yes         |
        timeVsFile   | List of time vs file    | yes         |
    \endtable
