hi,
how to deal with elements of questionable connectivity??can u pls tell me how to get rid of that issue
Hi,
I generally go for first identifying the elements having this connectivity issue.Then check for problems there like quad and tria elements getting overlapped, one of the nodes for a quad or tria is not connected etc. I go for manual correction for such elements.
one of the nodes for a quad or tria is not connected etc. I go for manual correction for such elements.
Works easy most of the time.
One can start with duplicates, finding the edges, free nodes using Equivalence and connect.
can it be done with tetra10 elements also??
I just want to add this information for all the future users who might have the same problem and might stumble upon this post as i did. I was able to solve it by looking for duplicates (check elements panel). After deleting them the issue was fixed.
Its good to start finding connectivity issues with options like finding Edges/Faces
You can find it in Tools-->edges or Tools-->Faces.
Here is an example for finding connectivity issue using Find Edges
"Find Edges" finds the edges of the element which it does not share with any other neighboring element.
Make sure the tolerance value is right for the model.
Thus in this picture, you should not see a red edge in the middle of the part. This shows there is a connectivity issue.
.
To equivalence the nodes, click preview equivalence and then equivalence the nodes.
Once the problem if fixed, check edges again to confirm.
