@东岳
李老师，

if (runTime.outputTime()) { volVectorField gradUx(fvc::grad(U.component(0))); volVectorField gradUz(fvc::grad(U.component(2))); volScalarField dUxdx_add_dUzdz ( IOobject ( "dUxdx_add_dUzdz", runTime.timeName(), mesh, IOobject::NO_READ, IOobject::AUTO_WRITE ), gradUx.component(vector::X)+gradUz.component(vector::Z) ); runTime.write(); }

U.component(0)指的是vx，U.component(2)指的是vz
我想问一下 gradUx.component(vector::X)中的X或者gradUz.component(vector::Z)中的Z分别指的是什么？是否与坐标轴一致？

@东岳 好的，谢谢东岳大神

在foam-extend4.0环境下根据openwiki的教程编译的fsiFoam4.0的程序（Extend-bazaar/Toolkits/Fluid-structure interaction），编译成功。
根据教程里的办法运行fsiFoam目录下第一个算例3dTube的时候报出如下错误，请问这是什么情况呢？
我在cfd-online上转了一圈都没有什么有效办法，很费解啊:136:

可以去看看funkySetFields这个工具

@xpqiu 是这个东西，看这个界面，我想起来了我遇到过。。。我说怎么没有调整的界面呢，右上角的设置忘了点开了

搞了一个乌龙

3q

加了引号好像也不起作用呢，都是显示读取了这个场文件，但是就是没有文件输出出来。

Thanks a lot, Dongyue. Very helpful. I found in SN model CdRe was multiplied by another Re. Thus, the formula is consistent.

@zhijie 好的，谢谢

@东岳 我使用的是自适应时间步长，保证最大的库朗数小于0.4。之前在文章中做过网格独立性验证，网格越细，下落的速度越慢，当网格小于一定的尺度后，达到一个“精确”的结果，液滴下落的速度不随网格的细化而有太大的变化

@xpqiu 亲测好用！感谢大佬！:xiexie:

目前 paraview 没有这个功能。

各位大佬，我在用rhoSimpleFoam模拟纯气相流场时，求解两个时间步长后，会出现下面的报错。
8WBKY)R_)V3F4VV$7_{4IAN.png ，请问是我哪里出现了问题？

@Samuel-Tu 在 Guass定理对方程进行离散时的困惑 中说：

@warnerchang 我估计你的问题在于，一个单元有六个面，这个单元不是有六个owner和六个neighbour，而是owner+neighbour=6

老师，谢谢您！我明白你的意思了！

@东岳 感觉还是自适应网格的问题，我去掉了dynamicMeshDict，就能算了 :136:

@Samuel-Tu upwind只有一阶精度，更对得上其他论文的数据，得查看其他原因了

现在很多研究采用的是waves2foam造波工具箱集成到OF中。我用的是OpenFoam1906版本，这套版本中有自带的造波工具箱即原来的ihFoam，所以我就不想再用waves2foam了。但是这个版本中造波后如何提取任意一点处的波高随时间的变化呢，有没有用过的大神。

目前我在controldic文件中添加了一段代码能追踪自由波面，但是提取的文件也是vtk的格式无法打开，恳请会的大佬不吝赐教！感激不尽！

@东岳 在 微分公式OpenFOAM编程 中说：

volVectorField t = fvc::grad(wbeta);
volScalarField t2 = t.component(2);

我有试过求梯度，再求分量，通过源项的方式加入微分方程中：

volVectorField t = fvc::grad(wbeta); volScalarField t2 = t.component(2); fvm::div(phi, beta)==-fvc::su(t2, beta);

这样可以吗:134: 。。

你的连接可以打开 但是我这网速比较慢 只有文章的第一页 明天我再看看吧

文章挺有意思，目前不清楚是不是CFD指导实验设计，还是CFD用来辅助实验验证。看起来确实可以用interFoam来算。

@a602657563 非常感谢，我好好研究一下

谢谢东岳老师回答，每个网格应该都是有粒子存在的，您说的第一种方法扩大出口区域，是像下面这样吗

第二种把P改成P_rgh以及可压缩处理啥意思没太听明白，论坛上也没翻到相关的东西，老师能再讲清楚点吗
