@浪迹天大 老师您好，按照这个方法，我需要更改controlDict中的maxDeltaT。但是会发现文件更新不起作用。

(1e-4 "$FOAM_CASE/system/controlDict.b")
(2e-4 "$FOAM_CASE/system/controlDict.c")
);
}
}
三个文件只有maxDeltaT有差别，请老师捞捞@李东岳 @浪迹天大
运行后结果提示：
timeActivatedFileUpdate: copying file
"~/orifice3Da/system/controlDict.c"
to:
"~/orifice3Da/system/controlDict"
Courant Number mean: 2.0171174e-08 max: 0.3369988
Interface Courant Number mean: 2.978204e-10 max: 0.22052861
Capillary Number: 2.4526254
deltaT = 2e-05
Time = 0.00022
文件有更新，并且maxDeltaT也更新为了1e-5; 但是它没有发挥作用，可以看到文件更新后的deltaT 依然是 2e-05，如果是我自己运行过程中手动改小maxDeltaT，它会马上从deltaT = 2e-05，便为deltaT = 1e-05。
