这个不是已经 commented 了吗？所以问题不在这里。constant/flowProperties 应该选择 interFlow

1224143516 · 2020 年3 月 20 日 07:35

已经用了interflow了

chnrdu · 2020 年3 月 20 日 07:38

能看看在出错信息的前后吗？

这里已经计算完一个循环了，说明基本流程没有问题。
需要一些调试，可能尝试用

Info << "X Y Z..." << endl;

添加到程序的一些关键位置，查找哪个环节出了问题。

1224143516 · 2020 年3 月 20 日 07:53

好的谢谢你这估计要慢慢查了我先系统学下，本来想先把程序跑起来再慢慢学的

1224143516 · 2020 年3 月 21 日 11:06

博主你好… 我发现了我那个问题应该是因为interflow.C和.H成员函数缺了几个，可是完全无从下手怎么改… 请问这有教程吗难度太大了

chnrdu · 2020 年3 月 21 日 11:19

修改的难度并不大，看你对 C++ 的掌握程度。如果是初学 C++ 的话，还是需要掌握基本的 C++ 一些基本的东西。

1224143516 · 2020 年3 月 22 日 04:53

大神你好这个报错我应该要怎么改我把剩下的成员函数都加上了

1224143516 · 2020 年3 月 22 日 04:54

是在make里面没有这个的路径吗

chnrdu · 2020 年3 月 22 日 07:14

不是简单地把函数都加上。要考虑你使用的变量，根据库的情况修改一些名称，把 U p alpha 相关的程序段都 copy 到 interFlow 的文件夹，按 interFoam 的模式修改 evolve() 函数。需要的主要变量都在 .H 中声明，并利用构造函数初始化。

cfdwired · 2020 年3 月 22 日 08:39

说起来简单，但做起来还是需要一点时间和功力。

确定你所需要的变量，在 .H 文件里面声明， .C 构造函数里面初始化；
按 interFoam 中求解的模式，copy 相应变量的求解程序段到 evolve() 中，也可以把这几个 alphaEqn.H UEqn.H pEqn.H 拷到 interFlow 里面，但相应的变量要修改。

1224143516 · 2020 年3 月 22 日 14:29

先谢谢两位大神了. 我研究下有时间没功力

Turbulence · 2020 年8 月 17 日 07:26

你好，请问传输模型里面nu无法识别的问题你后来解决了吗？
我最近也在学习这个FsiFoam，发现使用自带OpenFOAM自带工具提取力的时候需要用到nu这个数据，但是也显示这个关键词没有定义，可是明明已经在文件中定义了。

1224143516 · 2020 年8 月 25 日 07:52

这个求解器的固体是柔性的…会很复杂，我换了一个…

chnrdu · 2020 年8 月 27 日 03:52

是的，这个是求解流固耦合问题的，固体是有变形的。

不知道你要研究的问题是什么情况？

Turbulence · 2020 年8 月 27 日 05:09

我想研究柔性体和六自由度运动的刚性体共存的问题，就是不知道能不能实现

joezhr · 2020 年11 月 20 日 02:56

你好我也是刚开始学习fsiFoam 请问可以分享一下这篇论文吗

1224143516 · 2021 年7 月 22 日 01:14

请问固体类似于颗粒型的，产生滑坡涌浪，能实现吗？

chnrdu · 2021 年10 月 8 日 07:23

那这个固体就是颗粒流体了吧？产生滑坡涌浪的话，也应该可以实现
