请问ICEM输出的网格，Fluent可以用吗？

gduwang

一般用针对Fluent，ICEM生成网格时要注意什么？
谢谢。

ICEM CFD生成的3D网格输出成Fluent格式可以在Fluent中直接打开，2D格式的Fluent网格在Fluent中读入会出错，可以先存成CGNS格式，然后用Gambit打开存成Fluent的msh文件

哦，难怪我现在直接导成二维的不能用。不过我以前用5版的时候我导出过二维的，11版的就不行了！

查看了一下cfd－online上面讲的，需要输出非结构网格，因为fluent是非结构网格求解器，有没有人论证过？

cupidvenus

我试过，没成功。我找到的方法就是我前面说的那种，谁有简单的方法还请告知我

奇怪，有时用非结构网格输出msh文件能在Fluent中读入，有时不行

Step-by-step:
1. Generate the pre-mesh
2. Right-click on pre-mesh and select "Convert to unstructured mesh"
3. From the mesh edit menu, run Check Mesh to make sure that everything is OK
4. Save the project
5. From the "Output" menu tab, select Fluent 6 as the solver, then set up the boundary condition types, then write out the fluent.msh file. It will ask you which *.uns file to load, but if you have saved the project, the default should be right.
6. Accept the defaults and it should write a file called fluent.msh , which always works for me.
7. Optionally, from the file menu, close the mesh, save the project, exit icem and delete the *.uns files.
8. Optionally, gzip fluent.msh, then load fluent.msh.gz in Fluent.
1.save the mesh and go to OUTPUT. 2.select the FLUENT solver with version. 3.Click on write input(file window will come) 4.select the mesh file which u want to export and click open. 5.export window will come, u can enter the name in the column of output file. 6.the file will be saved in .msh format.

这些是从CFD-online上面找到的方法。

我知道这方法，但有时正常，有时出错，不知是否D版原因
