missing internal contact bounderies when convert to solid

Hi,

I have problem with introducing internal contact boundaries. A model consists with two glass plate and two cylindrical objects (model-glass plate contact with cylinders). The cylindrical objects are transversally loaded by the upper glass plate. The cylindrical objects have different material properties so the assembly method was used. To introduce contact behaviour in between glass plate and cylinder, points were used following cylinder_roller_contact example (Structural mechanical module -verification model). When I convert all the objects into the solid internal contact in between two cylinders are disappearing. I tried several ways to get that boundaries as contact pair but couldn’t.

Any comment is greatly appreciated

Thanks
