Remove 3D elements free edges
Altair EmployeeI know someone has asked this topic before. However, all the solution I found did not work on my case.
I used 'edges' to find the free edges between two hex elements. I have tried to remove it by ' equivalence ' and by deleting the elements and creating them again. When I checked the nodes on the two hex elements. I found that there is one shared node has two ID numbers. So I also tried to replace one ID with another ID. None all these methods worked.
Please help me.
Thank you very much!

Altair EmployeeSo does it mean that I don't need to worry about the free edge for my case?
Altair EmployeeActually when I used 'face' function. I found a face between the two elements. 'Equivelance' did not work as well.
Could you show a photo?
I checked your file but don't see it

The other edges are correct. Only these two are related to connection and should be removed.
Thank you very much!
Hello jacobier,
The left of the two masked (hidden) elements (yellow, Reissner's membrane) is at fault.
It's a degenerate hexa element, rather than a penta. Therefore, at this point, the nodes can not become equivalence.

Altair EmployeeHi, Mario
Thank you very much! How can I solve this? I have tried deleting the element and manually making penta element, but the problem remained.
Hello jacobier,
Delete the element and make a equivalence check (display all before).
Then you can create a new one.
Best Regards,
Mario
Altair EmployeeAfter I deleted the elements and displayed all, still 0 nodes were found for equivalence. Can you try that for me, as I have uploaded the model.
Hi jacobier
The Edges panel functionality applies only for 2D shell elements

Similar connectivity check for 3D elements can be done only in faces panel ( Tools > faces )
