OpenFoam定义新边界条件问题---通量边界
-
最近需要计算一个壁面传热传质的模型，结果发现fluent中的壁面边界条件在组分输运上只有两个选项，一个是质量分数，另一个是零梯度。
所以计划利用openfoam编写一个组分或者热量运输通量的边界条件，参考了网上的一个相关教程（https://wenku.baidu.com/view/67aeca451fd9ad51f01dc281e53a580216fc50ea.html）
但是在创建边界的过程中总是报错。这种边界有人建立过吗？未标题-1.jpg

-
这边参考网上陈丽萍老师的教程，但是编译总是出错，是不是版本不支持了？我的是5.0版本
-
尝试编译过程发现提示.C的173行有问题

没细看，不过单独看这一句，是版本不支持

最近尝试修改，整理完成后边界可以编译了，但是放到计算文件中还是报错，提示错误如下，有人知道这是什么原因吗？

边界条件编译了， .so文件也添加到字典中了，还是提示Unknown patchField type newgrad for patch type wall，这个好让人困惑。。。
-
检查发现是在字典中少将libs 写成了lib，修改之后还是出错，不过边界条件可以识别了。

有人知道下面这种错误的原因吗？
myicoFoam: symbol lookup error: /home/a/OpenFOAM/a-5.x/platforms/linux64GccDPInt32Opt/lib/libnewFvPatchScalarField.so: undefined symbol: _ZN4Foam21newFvPatchScalarFieldC1ERKNS_7fvPatchERKNS_16DimensionedFieldIdNS_7volMeshEEERKNS_10dictionaryE
-
看起来像是调用了一个过时的lib，库和求解器全部重新编译一下
-
@东岳 好的谢谢东岳老师，我试一下
-
@general 在 OpenFoam定义新边界条件问题---通量边界 中说：
您好，您最后这个边界条件成功了吗？是变通量边界条件吗？谢谢！
-
@Jhhu 你好，我最后没有成功，由于时间很紧张，还是使用了商用软件。
