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?
Currently it's not possible to merge the nodes directly. This is due to the way the Apex solver works with its Computational Parts. In a future release you will be able to have common nodes between Parts.
Right now to connect the Parts you can use the tools in the Interactions palette: Mesh Dependent Tie (previously called Edge Tie) or Mesh Independent Tie (previously called Glue), depending on how you want to handle the connection.
