What would be appropriate ways of checking meshing qualities such as continuity or checking whether elements/surfaces are composed of two or more regions joined at discrete nodes?

One thing I was able to do from Hypermesh was that

Tool-> check elems, and click connectivity,
Then, I got a comment at the lower left corner saying '2 elements were found with questionable connectivity' but I do not see where those 2 elements are located at.

How could visualize these 2 bad elements as well as would you recommend any other ways of checking meshing qualities for Abaqus solver so that I could fix those bad meshes?

Thank you very much!

Sincerely
SongJoo

    Hi Songjoo,

    When you get the questionable connectivity message, just click on save failed in the same panel.

    Then you can go to mask > elements > click on the yellow entity selector > retrieve > mask > reverse
    to locate just the failed elements.

    In fact another better way to identify and fix connectivity issues is using tool > edges as shown in the image below.

    Please see this VATS session on element quality issues and how to address them.
