OpenFOAM利用timeActivetedFileUpdate函数在计算过程中更新配置文件

偶然间发现OpenFOAM-6中，可以根据时间来选择计算时使用的文件（未测试），参考链接

例如，可以根据时间选用不同的fvSolution文件：

     fileUpdate1
     {
         type              timeActivatedFileUpdate;
         libs              ("libutilityFunctionObjects.so");
         writeControl      timeStep;
         writeInterval     1;
         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")
         );
     }

也可以更新其它文件（未测试），参考链接

    fileUpdate1                  //substitute a file at a given instant
    {
        type              timeActivatedFileUpdate;
        libs ("libutilityFunctionObjects.so");
        writeControl     timeStep;
        writeInterval    1;
        fileToUpdate      "$FOAM_CASE/constant/dynamicMeshDict"; //file to be substituted
        timeVsFile
        (
            (-1  "$FOAM_CASE/constant/dynamicMeshDict.1")        //substitution at t=0s
            (0.3 "$FOAM_CASE/constant/dynamicMeshDict.2")        //substituition at t=0.3s
        );
    }
