How to prevent RBE2-only fastener realization when only one panel is present in nut CAD location?

I am using the Fastener tool for creating the FE representation of bolts (RBE2 for head, BAR2 for body with "bolt (washer 1)" connector control). While creating fasteners using solids (in my case, nuts) as identifiers for FE creation on an already existing 2D mesh, connectors are realized and RBE2 elements are formed even if there is only a single panel at the solid location. For other locations, RBE2s and BAR elements are created properly as per the tolerance. How can I avoid this issue? (Hypermesh version 2023.1)

Hello

Make sure your options are set to realize the correct entities (Parts) and number of links

Here you can see the Solid CAD with only one mating hole did NOT create a connector

Thanks for the reply. When multiple panels are within the set tolerance and a hole is not present on one of them, the connector is not realized (as shown in the image). However, when only one panel is present near a solid location within the tolerance, the connector gets realized with a single RBE2 element. That’s the issue

Can you share the model?

I cannot share the model, but I am sharing the image of above situation.
