OpenFOAM获得某个区域平均温度的方法

可能你已经找到理想的答案了。但还是想分享一个用法：

    volFieldValue1
    {
        type            volFieldValue;
        libs            ("libfieldFunctionObjects.so");

        log             true;
        writeControl    writeTime;
        writeFields     true;

        regionType      cellZone;
        name            c0;
        operation       volAverage;

        weightField     alpha1;

        fields
        (
            p
            U
        );
    }
