modal analysis of composite structure

[Rosta_Spicl]

Dear experts

I'm just frustrated about very primitive exercise in Creo Simulate 12. See the sketch below. In creo there is an assembly contains 2 composite parts, in real glued together. The cored composite board (composites 1) is bonded on composite frame L profile (composite 2). The target is to see how the rigidity of L profile affects the modal frequencies of board.

Only composite quilts are supported in Simulate, it means the virtually gap is observed, the layup guilts are not in touch, bonded connection is not supported in this case. I have tested a lot of procedures, rigid link, spot weld...etc., but only bonded interface is closest to real surface - surface bonding.

Another test I have made, in assembly the 3rd part - glue was created, the thickness was a gap, but there is a material interference - glue + laminate in real. 

Does anybody have an idea how to fix that? What is the correct connection feature between two composite parts, or generally between two shells?

Thx a lot, Rosta
