发帖数: 3 | 1 Hi,
I am a new beginner to FEM and just started to use FEM to simulate 3D fluid
flow to solve N-S equation. We have our own mesh format which is different
from FLUENT, so I need to change mesh format. Is there anybody could tell me
what's the format of FLUENT mesh or send one copy of FLUENT mesh? I search
online, but cannot find it.
Another question is I have already tried COMSOL to simulate, but it seems
COMSOL is bad at 3D. I have no idea whether FLUENT will be good? Is there
anyone have good | j****x

mesh file that it can handle. | w******n
发帖数: 645 | 3 Fluent should be a FVM based code, not FEM, if I remember correctly. People normally use external package to create mesh to use in Fluent, such as Gambit. | s**********a
发帖数: 3 | 4 Thx for that. But seems it just has example for structured mesh, how about
for unstructured mesh?

into some mesh software such as GAMBIT/ICEMCFD, and then save to FLUENT mesh
format. | h****l

反正mesh转换这些就是用几个软件来回转，反正mesh文件就是点单元的数字信息呗，大
不了自己写fortran改格式，肯定可以找方法给转换。 | s********s
