Hello all, I need some help. I'm performing a structural analysis (integrated mode, WF2), using shell elements. The model was meshing fine until I created and then deleted a contact region. After deleting the contact region, it left behind the symbols circled in red. Now when I try and mesh the model I receive error messages stating shell pairs are defined for surfaces, but there are no material properties associated with them. I went through each individual part (twice) and ensured material was assigned to them.
What are the symbols created from deleting the contact region and any ideas as to why I'm getting the material properties error message?
