Dear all,
As shown below, you’ll see two surfaces, one before “imprint” and the other after. I got a new surface with two curves at the top and bottom, which connected the two visible surfaces to each other. So, I’ll get some errors later with meshing.
Now I try to split them into two surfaces and delete the short curves between them. It doesn’t matter which way I try, I’m not able to get the wish result.
Which option do I have to divide these surfaces? (The Surface is one Part of a Volume (take a view at the tree))
Best regards
Michael
Surface one without imprint
Same Surface with imprint
Volume with data-tree
Hello @Michael_Polito,
could you please share the geometry with us. I would need to reproduce this behaviour.
Hopefully the upload works.
The CAD-Data is built up as simply as could. There are still some small parts which could be built up better but before I do it, I will figure out, how high is the impact on the mesh quality.
Step by step I want to eliminate the problems.

Hello @Michael_Polito,
you could use the tolerant imprint to handle this surface.
doing
imprint tolerant volume all tolerance 1e-3
instead of imprint vol all
But the geometry in general is not that good if you want to prepare it fast. The cause for the above surface issue is just a bad tolerance. The gap between the curves was too big. You should check the geometry with the power tools.
There are some small features that will cause trouble.
Yes, I see your second example also before, one of the bugs to repair.
Also, surface 16 (hopefully it’s the same for you) makes some problems. I still reduce the mesh size but it doesn’t help. I check the geometry size and the mesh size is high amount smaller than the geometry but still the error
“ERROR: Mesh break-out occured.
Try modifying the curve mesh intervals or mesh size.
(Usually decreasing the element size, or increasing
the number of desired elements will help.)
ERROR: Surface 16 meshing unsuccessful using scheme: pave
ERROR: 1 surfaces(s) did not mesh : 16”
surface 16
So I’ll find here the explanation for the power tools.

On my machine it just meshes the surface.
I can’t execute your whole journal to the point when you are meshing. I don’t have the plugin available that you are using.
Can you provide a journal that will show this behavior when using cubit without any plugins?
