Hello, everyone.
I'm fresh to ICEM software. These days I made a simple geometry in the ICEM, then made some blocking, but the quality of the mesh seens not so good at some places. But I really don't know how to repair it...
The check result is like this..

Thanks!

This is my file...

Hi, huihui

Could you upload your file? The problem is not very clear only by your picture?

Best,

From your picture, I can say there is an association problem.
The bottom edges and vertices seem to be associated to top curves and points (we can see green arrows on your picture ..).

yes, there are some big green and black arrows in my association, but I don't know what's meaning of it...
The channel has a slope about 0.04, so the left down edges of the block should be associated to the upper curves.
could you tell me how to fix this?

thanks a lot!
Best,
huihui

Huihui, the arrows show to which curves (or points) your edges (or vertices) are associated to.

I changed the association as you guys said, it works some part, but the some places are strange.

1.jpg
2.jpg
3.jpg

as the picture show, I want to associate two kind of places, A TO B, and C to D,
the first one is ok, but after I associate C to D, it seems that there is no vertices.

How can I fix this, or did I do it in a wrong way...

I know where is the problem, the place B also have vertice, so I just merge the vertice at place B and place A, after that, associate the vertice and point.

I don't know why, but it worked.
