@东岳 我在速度文件力设置好内部速度为定值（0.6），压力文件里设置内部压强（1e5）通过一段时间计算后，流速越来越大。像我需要指定初始速速，只需要设置速度文件，压力文件中设置为0就可以，或者将指定的初始速度转化为相应的压力添加在压力文件中，速度文件设置为0呢!1.png 2.png

@xpqiu 感谢老师详细指点，试了下这个方法确实简洁:xiexie:

这是没有编译成功吧，我在foam-extend-4.0+2.4.0上面编译成功过这套程序

计算发散报错如下：
报错.jpg

@刀尔東 你好，我想问一下，在后处理中想对一个量做加减运算，这个在后处理里应该是什么指令呢？比如对速度U的模取反，postProcess -func "-mag (U)"，这样是报错的，不知道应该怎么处理？感谢:146:

@cccrrryyy 好的，感谢解答，我再思考一下:quwan:

@东岳 :146:

@东岳 感谢李老师啦:146:

我在尝试使用foam-extend4.0的浸入边界法时，并行也总是出错。后来改用foam-extend4.1的浸入边界法pimpleDyMIbFoam，分块并行的时候没问题，reconstructPar的时候出现段错误:zoule:

@bestucan 好的，谢谢大佬哈。第二篇我看过，是不动的。柔性的里面还是有些区别的，我只能对流体部分进行主动控制，固体不会动的，现在不知道怎么样让固体整个转起来，而且对于偶合面的主动控制不知道会不会对变形有影响。主要是找不到那种算例学习

@cccrrryyy 好的，谢谢您，我再查阅下相关文献看看

@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
