Hi there, thanks for the link.
The (possible) bug is in my 1st post in this thread. COQUE_3D with tied contacts (LIAISON_MAIL) causes a crash, see fig below. That NS node is created by code_aster, as it needs a mid-face one for shells (coque_3D) to work; hence the question, it shouldn't crash with the tied contact (?).

Solved in V16.5. Here are the files for this tiny test model: tied_shells.zip
