Hello everyone,

I’ve created the geometry，but I don’t know how to mesh it。

Hope you can take some time to help me solve it。

Here is my cub5 file.

Hi @stupid_me,

a little decomposition is needed as we need some sweepable volumes.

```
reset
open "C:/Users/user/Downloads/model.cub5"
reset vol all
webcut volume all with plane xplane offset 1712
webcut volume all with plane xplane offset 1726
webcut volume all with plane yplane offset 8
imprint vol all
merge vol all
```

We can already mesh it now. We just have to make some mesh settings and make sure that we first mesh the cylinder and the adjacent volumes. Afterwards we can mesh the side surface with the pave scheme. This will then get sweeped through along the y-axis.

```
surface 602 size 1
curve 1086 size 1
surface 753 size 4
volume all size 30
Volume 14 13 size 4
Volume 63 64 size 4
Curve 1124 1149 size 4
Surface 753 scheme pave

```

If you need more mesh control you will have to decompose the geometry further. Also you would gain a better mesh quality if angle in the cut from the cylinder wouldn’t be so sharp.

I hope this gives you some ideas.

Thank you for taking the time to answer my questions. Your approach to meshing gave me great inspiration. Through your example, I understand how to use cubit when the geometry difference is too large. I will learn from your steps and think about how to get a more suitable grid.

Thank you again for your answer.
