关于网格尺度小了以后interpolation和mapping的问题

这个算例太酷炫了 小液滴都算出来了 还特别圆

@chengan-wang 在 关于codedFixedValue使用 中说：

我定义了ymax，之后如果我使用if ( Cf[faceI].y() > ymax ) 设置相分数，时间步长越来越小。但如果改成if ( Cf[faceI].y() > 0.1 ) 一个具体数值，情况就好很多。我的使用方法是否有问题呢？

理论上不应该有任何问题 :jingya:

@tower 老哥，请问下问题解决了么:143:

@samuel-tu OpenFOAM网格可以转换成Fluent的.msh，但是用于OF的二维轴对称楔形网格不能直接转换成Fluent二维网格

@freeman 您好，makeAxialMesh好像确实只更新到了2.x版本。我在OF2.1.x下使用，目前看起来是正常的：

@浪迹天大 这样嘛。。。好的，谢谢！

@李东岳 确实有一些冲突，修改很麻烦，我上传一个PDF版本吧。

如题，想用Foam-extend里的浸没边界法（Immersed Boundary Method）求解器，解决水与弹性杆的流固耦合数值模拟，有人有这方面经验吗？

@yu_tian 请问您解决这个加密不均匀的问题了吗？

@static 你好，我最近也在做三维飞机的相关数值模拟，可否给个联系方式，请教一些问题。谢谢，这是我的qq：3310792254

在一些文献里面我看有人这么用，更简单：
$$
\varepsilon=\frac{\mu_{eff}^3}{\rho_c^3(C_s\Delta)^4}
$$

Simulation of coalescence breakup and mass transfer in polydisperse multiphase

@李东岳 很抱歉才看到老师的回复。感谢老师，我已经自己解决啦:xinxin:

图挂了

@李东岳 东岳老师，我在dynamicMeshDict里设置了constrints和restraints两个条目，控制圆柱仅在y方向移动，不转动，如下：

constraints { yLine { sixDoFRigidBodyMotionConstraint line; centreOfRotation (0 0 0.5); direction (0 1 0); } noRotation { sixDoFRigidBodyMotionConstraint orientation; } } restraints { verticalSpring { sixDoFRigidBodyMotionRestraint linearSpring; anchor (0 0 0.5); refAttachmentPt (0 0 0.5); stiffness 2.1055; damping 0; restLength 0; } }

不知道您说的是不是这个意思？

@李东岳 感谢李老师百忙之中指点！这么来看correction(fvm::ddt(p))就代表前后时间步压力差值的时间变化率啦

@李东岳
老师好，用的interFoam和twoLiquidMixingFoam，是VOF？

各位大佬好，想请教一下，我想显示一个密度、体积不断变化的物体的质量，请问大家有什么好办法吗？

屏幕截图 2021-06-05 161820.png openfoam自带案例interPhaseChangeFoam求解器下的cavitatingBullet，该图为我跑完0.05s后的水相分布，和0s时没啥变化,请问我哪里错了吗？

@李东岳 感谢李老师回复，我先试下

@exthan 你好，我想画一个这样的网格，但是目前没有参考的例子，您放不方便上传一个简单的案例提供参考，谢谢

@悬浮的猪 有pdf不，不在学校下载不下来

@李东岳

我用下面的命令解决了 ，具体为啥不清楚..

sudo ntfsfix /dev/sdXY

https://askubuntu.com/questions/145902/unable-to-mount-windows-ntfs-filesystem-due-to-hibernation

@李东岳 好的李老师，我明白了，特别感谢您！！

@五好青年 强烈表示+1！我也测试过，感觉多核并行计算会使得分区相邻的部分衔接不上，导致计算有问题

@李东岳 谢谢老师的回复！

@鲸落 其实也不是只显示一层。我想你跟我当时一样，感觉摄入粒子很多，其实由于体积太小，所占的相分数其实不大。那么最后就会只有一层。如果有很多粒子的话，最后会形成很多层，因为只要满足你预设的最大相分数，它就不会再允许粒子进入，那么就会在其上方的网格中开始堆积。

@tens 学到了，感谢老师的指点！:chitang:

@hongjiewang http://dyfluid.com/rhoPimpleFoam.html 这个你看过没老铁

不论喷入多少颗粒最后都是底下薄薄的一层，就是堆积不起来

@李东岳 在 请问如何把pbm耦合气液多相流算例中？ 中说：

？

博士论文方向是做搅拌釜内的气液两相流，由于版权问题只能用openfoam来做了，由于课题组之前在fluent有一定pbm基础，所以还是想用pbm来模拟，具体方向主要是反应器的设计的实验研究，把实验结果通过模拟对比一下，不是openfoam的攻坚:chouchou: 所以暂时还是追求着能用就行的原则来，后面可能对模拟精度要求高了，就要自己深入研究算法了:135:

@李东岳 好的，谢谢李老师

@zhouxu 如果是h的传输方程，就不能有calculated边界条件。你可以把你的温度边界赋值给h，类似;

volScalarField h ( ( ). mesh, T.boundaryField().types() );

@bestucan 太感谢了，非常有针对性的网址，谢谢！

官方没做，然后各做各的，互不相通，版本就多了。

还有interfsifoam呢

第二个问题，怎么总感觉有人问过？不是你又问了一遍吧:chigua:

权限不够是下载的源代码权限设置有问题。用chmod修改权限。

各位大佬，如果我想在openfoam里自己新建个固体结构，由散点组成，上面的物理量要插值给附近的流体cell，但是并行时候，因为docompose了计算域，会可能出现一个散点周围的流体cell不在一个domain，那这种情况怎么处理呢？

@hotairballon1997
kinematicParcel中先看move部分，

初始化各个参数，计算lagrangian 步长。 更新参数，setCellValues，计算dispersion，然后calc方程 在calcVelocity中得到新parcel速度，新parcel速度calcVelocity部分中计算parcel受力得到新的parcel速度，返回到calc中，然后在calc中，根据 1-way 2-way 计算parcel是否对流场产生影响 然后返回到move中。。

https://openfoam.top/sprayVelocity/

所以Q1 在你不说你的模拟是1way 还是2way 是无法解释的
Q2 在上面的链接一定程度上可以解释一些

Explicit contribution, Su specified as a force Implicit coefficient, Sp specified as force/velocity

@yfleung 这个具体没写过，找找定义模仿现有程序试试吧

@baojd42 想请教下您，最后成功了吗？RapidCFD可以在GPU上完美运行吗...谢谢了

大神们好！
我的课题中涉及到快速求解室内（三维室内空间）的流场（一般ke模型就可以了），通过前期的文献调研了解到physics-informed nerual networks可能是解决方案之一，现在也在这个方向上努力。但该方法还是涉及到求解几个边界条件的室内流场做训练样本。

所以想到了用python调用OpenFOAM来求解指定边界下的室内流场，然后带入到python中的PINN里用于训练模型，了解到已经有可以调用的PyFoam包，但没尝试过，也没用过OpenFOAM，想问下有经验的，这条路子走得通吗？（有Matlab和Python的编程经验，上手OpenFOAM难不难呀，因为案例不会很难，就是常规的很简单的不可压缩流体流动，最多涉及到一个浮力的boussinesq假设）。

第二个问题，就是python里的PINN模型在训练时的高效性是基于GPU实现的（所以是租用了GPU服务器，不支持/不鼓励用CPU求解），所以在python里调用OpenFOAM时，想让OpenFOAM也基于GPU计算，这成熟吗？或者有现成的解决方案吗？

第一次涉足OpenFOAM，可能问的问题很不专业，见谅！

@calf-z-dns 你解决了吗?

我也在查 Reynolds Shear Stress, 和 Reynolds stress 有点分不太清楚.
http://brennen.caltech.edu/fluidbook/basicfluiddynamics/turbulence/reynoldsstresses.pdf (http://brennen.caltech.edu/fluidbook 公式的索引)
这篇上还有个 Reynolds normal stress ...

@samuel-tu 是的，超算还是划算些。昨天跟阿里云销售确认了下，他们的vCPU除以2是物理核心数，按他的说法是ECS所有服务器都是这样的。

@samuel-tu 在 bluecfd编译巨慢 中说：

没办法windows系统上word，ppt需要用的太多了，用同一个系统比较方便。。

我也没解决办法。ubuntu开虚拟机开word、ppt比较卡。用libreoffice、wps一大堆的格式问题。因为我这面处理的都是小文件，不需要写基金本子，所以还是ubuntu系统了

@李东岳 谢谢老师的指导，用interFoam -postProcess -func yPlus成功了。

@李东岳 谢谢老师~希望以后有机会能读到老师对这部分的分析

@blookcfd 感谢您的回复，
请问这种语法比较常见吗？
这个objectRegistry::template是指代的 Type类型吗？

@xpqiu 1799361277@qq.com 谢谢大佬
