Check and Fix Boundary Shell Intersections in HM 2019

Hi everyone,

I have just used HM 2019 version and see a new feature (Check 2D Mesh) in tetramesh panel.

<?xml version="1.0" encoding="UTF-8"?>

I have read Altair's Help but I can't apply this feature to my model. When I clicked the fix button, the intersection elements are deleted.

<?xml version="1.0" encoding="UTF-8"?>

Has anyone used this feature yet? How do I use this feature properly?

The attachments below are my model file.

Thanks in advance.

IMHO you have to fix your surfaces firstly, before making your mesh by doing equivalence of edges. You have to have all green edges.

Geom => edge edit => equivalence

Thank @Q.Nguyen-Dai.

This link below contains the HM 2019 slide.

I keep the red lines because I want to create the same model as on the slide (page 12). I want to try new feature (Check 2D Mesh in tetramesh panel).

Have you used that feature yet? Does it work correctly?

To try this feature mesh should be enclose and element failing in aspect(sliver).

Thank @Rahul R very much. To use this feature, mesh should be enclose. It works pretty well.

Thank again.

Dear @Khac Thanh, i tried to use this feature to repair Boundary Shell, but it didn't change at all. Then, I creat a very simple model, i.e., a cube, and manually creat a intersection shown as below. The situation is same, the mesh was not modified even though I did fix.

Could you show me how to use this function correctly? Thanks a lot!
