OpenFOAM如何输出场的最小值这个文件？

[Jhhu]

我想监测温度场的最小值随时间的变化情况。能否直接有工具输入最小值的文件？
我用的OpenFOAM5.x，尝试采用cellSource来输出，将functions加入至controlDict文件中。但运行计算后并没有输出结果，百思不得其解。
您的任何建议，都万分感谢！

functions
{
    cellSource1
    {
        type              cellSource;
        function          ObjectLibs ("libfieldFunctionObjects.so");
        enabled           true;
        outputControl     outputTime;
        log               true;
        valueOutput       true;
        source            all;
        operation         min;
        fields
        (
            T
        );
    }
}

你看看算例文件夹下postProcess文件夹下输出没有

[Jhhu]

@东岳 啊谢谢回复!我计算后，算例文件夹下没有postProcess文件，按理说应该有的吧，不知道您有什么建议。

把最开始计算的5个时间步log贴出来看看？

@东岳 谢谢东岳老师能回复我，开心。下面是你说的时间步log吧。我设的时间步长是240s。

你自己写的求解器？看起来你这个求解器没运行function

[Jhhu]

第一次发帖求助，就能得到东岳老师的回复，真的非常感谢！
（1）是根据laplacianFOAM稍微改了下的求解器，但是如果是探针probe的话是可以运算出结果的。那cellSource不运行function的话，我需要怎么改下求解器吗
（2）还想请教下，算例边界条件设置的问题，左图是压力，右图是温度。
左图压力上下边界条件均为zero flux，右侧问题上下右边界条件为zero conductive flux。对于zero flux和zero conductive flux，边界条件是不是应设置为symmetryPlane，还是zeroGradient。我计算出的结果差别很大，不知道问题出在哪里，所以想确定下是不是我边界条件设置的不对。
