Node merging for bodies of two differents parts.

kenny.fernando.conto
I made the model by parts due to each part has different mechanical properties. I would like to marge the common faces nodes but, unfortunately, MSC Apex can not realise that procedure if the bodies created belong to different parts. How can I solve it? if that is not possible, What is the best method to mesh the geometry and that the common faces nodes being merged?

    Dear Darrel,
     
    Thank you for your reply. We need to do a continuous solid for our purposes (coupling with elastodynamic BEM). Thus, mesh independent tie is not valid for us. With the mesh dependent tie we cannot do the interaction between two solids, if I am not wring.
    Previously in Patran, if I remember properly, we were solving this issue by making that the geometric interaction surface of two solids in contact is the same. Then, when the mesh seed is applied on that face, it works in the same way for both solids. We you automatically mesh that two solids, the FE nodes appearing at that interaction surface are shared by the two solids. Can we perform a similar action in Apex?
    Another option is to have a single partitioned solid. In this case, how we can set different properties for the different partitions?
    Thank you very much
