把每个相的扭矩值都分别处理，然后相加即可，跟实验值较为吻合

输入which mpirun 看一下

可以考虑采用waves2Foam得波高仪进行监测，我以前做过这东西，把waves2Foam得波高仪添加到求解器中，然后就可以采用wave2Foam得波高仪probe监测自由液面，这种方法是不需要waves2Foam求解器waveFoam，可以用个人得求解器。这个是我以前做的，有兴趣可以看看https://github.com/byChen47/waveHeightGauge

@学流体的小明 感谢大佬，问题已经解决啦:146:

@jeffx 在 DSMC时间平均 中说：

@kuangyonglin 您好，请问在使用dsmcfoam+进行计算时，初始运行一段时间步数，计算就会停止是什么原因（并没有到达设定的endTime）04e55618-90e2-434f-a513-43536582d78c-image.png 639b9871-e77c-40d9-bf48-3bce389b7d7b-image.png

看不出来啊，看着 controlDict 看着挺正常的

删了我好多，这种情况需要重新wmake求解器吗？？

取一个或多个平行于壁面的面（Kim的图也是不同高度的，y^+=5.39和149.23），使用surfaces工具输出这个面上的速度，然后每个面计算速度的展向、流向空间相关函数就行了。
可以直接计算二维的相关。
也可以固定z坐标，一条线一条线地计算流向的相关函数，再做个平均。

如图，在做有关雾化的课题，但是在paraview中不知道怎么复现前辈的论文输出某截面的液相分数微信图片_20241221153039.png 微信图片_20241221153346.png 图片1.png

我在找bug的时候，在《无痛笔记》更新了一下openfoam无反射边界条件，目前来看植入的没有问题。bug应该不在这里。

是不是边界的名重复了呢

算出来的最低温度一直在降

数值扩散掉了

@Jimmy-Yao 楼主最开始的是四面体网格吗？

是的，你试试

@1064168551 在 求助：在codedict中读取求解器中定义的标量 中说：

@李东岳 a6bccb55-b62e-4688-bc61-dc2f9e6911e5-image.png 东岳老师，抱歉再打扰您，我现在改成这个样子，还是会报错，dimensionedScalar好像还是无法lookup

报错在这里，就还是这行const dimensionedScalar vv = mesh.lookupObject<dimensionedScalar>("vv");有问题

遇到了类似的问题，就是水平集模拟两相流时，怎么样利用水平集计算的相界面把一个对流扩散方程隔离开，只在一个相内求解对流扩散方程。

发散的话就是发散了，问题就很多，需要你详细的debug

好像是因为我没缩放网格
