你可以试试，支持性不是很高。对于简单地几何，玩一下挺有意思的。

@tens 明白了，十分感谢！

@星星星星晴 老师我最近开始做本科毕设了，非常感谢您的帮助和耐心讲解。后面可能还有知识要请教您，万分感谢！

我感觉有必要擦除流体与固体的试算结果，再进入下一个迭代步。固体好说，只有一个D，我令D=D.oldTime();就能把D的试算结果消去，但流体就很麻烦，因为有很多个变量，我试了半天也不知道该怎么把所有变量的值都擦除掉，恢复迭代前的值

没太看明白

@李东岳 东岳老师您好，我最近发现了一个现象可能造成了我上述提出的问题哈哈哈哈哈，我最开始使用的是DPMFoam默认的的Ergunwenyuforce曳力，我后来换成了sphereforce曳力就能稳定了，而且对于颗粒运动和流场有挺大影响，看来这和我的设置也有一些关系。（最开始图方便就直接使用的默认的模板了，看来还是要根据实际情况来改变）

csv可以读到paraview里面，然后渲染成云图

@疏影横斜水清浅
谢谢回复，是的，预计和你问题一样的，我正在重新检查代码，编译器不报错的话，只能一行行自己排查吗？

我做的用部分泡沫金属强化石蜡相变材料的传热。模型为长60mm、宽80mm的矩形，上面为纯PCM，下面为泡沫金属石蜡复合材料，两者面积相等，设置初始条件297K；边界条件为左壁面为恒温360K，其余三个面绝热，泡沫金属孔隙率0.8。现在迭代发散，不知道什么情况，求各位解惑。附图为相关参数设置

@下里巴人 你好，请问这个网格划分的文件你那里还有吗？能不能给我发一个呀，我最近也在画一个管道想相贯的网格，但是相关的地方一直处理不好

@星星星星晴 谢谢老师的耐心讲解！:xinxin:

请问下会了吗

Openfoam extend 4.0可以使用DensityBasedTurbo吗？

背景介绍的不完整，没太看明白是什么问题。

居然还发公众号了

在一个可压缩热喷流模拟中需要修改k-epsilon模型 引入温差和可压缩性的影响，需要用到温度、可压缩性等，请问怎么在原k-epsilon模型类里使用这些量微信图片_20220322153039.png
原模型Cmu是个常数 修改后应该是一个场量
具体一点的问题就是thermo.gamma()怎么接入湍流模型这个类里呢

目前这个求解器在OpenFOAM里面已经有了：shallowWaterFoam

@一颗鸭蛋

尝试过docker 没弄明白 当时M1还没适配docker 后来也懒得弄了
我是用parallel 装的ubuntu arm 自己编译的，跑的起来完全没问题。
跑分里面的M1 就是我的mini

@星星星星晴 好的，感谢您的指点！

@youhaoyu 1719302824186.jpg 看了本比较通用的书，里面把我第一张图里（1.15）直接写在方程里面的（我感觉这样写比较合适）。那么这个R0和Pg0我还是不理解什么意思，有没有大佬解释解释
