Error in solid element connectivity, the first 4 nodes must be unique

Altair Forum User

Hi, everyone

 

Thanks for reading this topic.

 

When I submitted a job, I got the error information:
*** Error 20222 (STR +222)

      in solid element connectivity, element 103338

      the first 4 nodes must be unique.

 

Then I find this element 103338 and check element, there is no problem with its connectivity and duplicates (see the bellowing picture). It is very confusing.

 

If I delete this element and translate + duplicate an adjacent one and then equivalence nodes, the error will still exist, but in another different element. I don't how many elements has this problem. 

I also tried renumber all, but it is still useless.

 

I really want to have your suggestions if you are familiar with it. Thanks a lot.

Try duplicating all elems.then delete the originals

Could you share *.fem file?

Hello,

 

Instead of translating and duplicating the element, can you please try and create a new element from '2D' page 'edit element' panel.

Thanks for your help. I can create new element use the edit element panel. But the next analysis will still have the error with another element.  I am really confused. I want to find out every element with this problem and correct them all.

Hello,

 

I would suggest you to try this method a couple of times but if the problem does not go away please consider re-meshing the whole thing.

 

Thank you
