使用fieldAverage，求解器正常运行，但没有输出fieldAverage工

[xumengxin]

各位老师，我想问一下fieldAverage应该怎么用呀，我使用的是interfoam求解器，想计算一下全域的平均压强，但是设置好fieldAverage后，在postProcessing中并没有相应的结果

用这个试一下

fieldAverage1
{
    type fieldAverage;
    functionObjectLibs ("libfieldFunctionObjects.so");
    resetOnRestart true;
    resetOnOutput false;
    outputControl   outputTime;
    fields
    (
        U
        {
            mean on;
            prime2Mean on;
            base time;//iteration
            windowType exact;//计算精确窗口平均值
            window 4000;
            allowRestart true;
        }
        p
        {
            mean on;
            prime2Mean on;
            base time;//iteration
            windowType exact;//计算精确窗口平均值
            window 4000;
            allowRestart true;
        }
    );
}

@ice_flow ！还是不行，老师

[xumengxin]

我好像明白了，平均值是结果文件中的pmean和umean

[ice_flow]

@xumengxin 对的，是这段时间窗口的平均值，对应的窗口值应该也有保存。

[xumengxin]

我一直认为会在postProcessing文件夹下生成一个目标值的文件。谢谢您！@ice_flow
