Selecting Outer Faces Using Ansys Discovery ScriptEditor

[to.81]

I have two parts where one is encapsulated by the other(imagine a layered shape, or like an onion). I want to select all the outer faces of the inside part and all the inner faces of the outside part in order to create a bonded contact. None of the faces of either parts share anything in common so I can't use the power selection tool. I've tried creating a bonded contact that is just Component1.ConvertToFaces and Component2.ConvertToFaces, but the contacts don't turn out the way that it should be if I had manually selected each component and created a bonded contact. Additionally, there are some faces that aren't touching the other parts at all and I don't want those in my selection. I just want to select the faces that are identical and touching between the inside and outside parts.
