Duplicate element IDs in the same deck runs without error. Why?

sudhish.kumar
I have a Sol101 analysis deck that has a set of element Ids that are duplicated.
 
A set of CTRIA3 /CQUAD4 elements have been given the same ID as that of another set of CBEAM element.
 
I am not seeing any fatal error or warning in the F06 file.
 
Why is this happening?

    As Don mentioned, Nastran allows you to do that, though it's a very poor practice. Plus, I don't know of any pre-processors that would support this...I assume most (if not all) would insist on renumbering elements if you import an input deck set up this way.
     
    This oddity of Nastran reminds me of the "stupid pet tricks" that David Letterman used to include on his late night show.
