第9分钟介绍这种High Aspect Ratio对于瞬态、稳态的具体影响。

@Vortex
感谢学长^_^

会不会是实验的冷却水产生的实际效果跟你模拟设置的边壁14℃是不一样的？

仿照https://www.cfd-online.com/Forums/openfoam-solving/60471-call-fortran-program-openfoam.html进行Fortran程序的调用，编译过程中报错： from chemistryModel/rho2ChemistryModel/rho2ChemistryModels.C:37:
/home/sy/OpenFOAM/sy-v1706/src/thermophysicalModels/strath/strathSpecie/lnInclude/CEATransportI.H:152:7: error: expected constructor, destructor, or type conversion before ‘(’ token
phypro(&TG, &TE, &PT, &PE, &CON[0], &CP_FINAL[0][0], &H_FINAL[0][0], &MIU_FINAL, &K_FINAL[0]);
但仿照https://www.cnblogs.com/snake553/p/6962386.html编写C++程序可以实现Fortran程序的调用

@wsy11 谢谢您~我现在已经可以成功构建网格啦^^

在计算单相流作为初场，可以收敛，但是湍流粘度比超限，继续设置为多相流空化计算的时候，开始发散，不知道有哪些解决办法，已经重新画过网格。
边界条件是速度入口，压力出口，湍流sst k-w，稳态计算

你是不是算的倒虹吸啊

各位大佬，我不小心在Ubunto家目录下执行了foamCleanTutorials，命令行报

删了我好多，这种情况需要重新wmake求解器吗？？

@李东岳已经非常感谢了，我再继续努努力吧！:expressionless:

我需要用ICEM画multiblock网格，几何类似于上图的模型，我知道三角形Y-block和圆形O-block，那请问这两个如何结合起来呢？在这种结构中它的edge并不共用相同的vertices
第二个问题是icem的multiblock的网格如何光顺？我尝试使用了pre-mesh smooth，但是这个功能很慢，容易卡死。我只知道可以用edit edge调整spline来改变edge形状，如果一个一个edge调是不是有点笨？

963df654ce25372fc5621513b9fe905.png 如图是blockMesh中创建的oversetPatch，用于触发在任何其他边界条件之前进行重叠（overset）插值。ccmTo.png 这张图的polyMesh是利用ccmToFoam，将starccm网格导入到OpenFoam的，请问如何在starccm里面加上图1中的oversetPatch呢。@李东岳

是不是边界的名重复了呢

只修改了粘度出现一下报错想问问该如何解决，粘度为2e-6m2/s

烦请各位大佬指点一下，workbench里面mesh画的带角度的翼型的网格，为什么边界层厚度不一样啊？怎么处理一下呢？上面的感觉太窄了

e9d97488-fa0f-453d-9f2b-1884d5136695-image.png

已解决，解决方案是scalarDict.set("vv", "vv [0 0 0 0 0 0 0] -0.1");

@李东岳
懂了，谢谢李老师！

@arctan 非常感谢！

@CiCi 同是做可燃介质的燃烧爆炸的数值模拟，应用背景放到了安全而不是燃烧利用。我想我猜到师姐在哪个组了。上网不涉密，涉密不上网（手动狗头)。目前这个方向的话大家好像都在往锂电池的热失控排气及诱发的爆炸模拟上转。

@LYHua 太感谢了，解决了，给力
