I have two .sat parts that are touching each other.  In CAE, i'd like to have 2 different material properties for each of these parts, but not have a contact condition between them.  They will be meshed as tets.  How do I make sure that the nodes from the 1st part are bonded to the nodes from the 2nd part?

Another option is to model the two parts as one .sat part.  The 1st part is a cup and the 2nd part is a sphere.  Is there a way in CAE to create a spherical shell and separate the one .sat part into two different bodies of two different materials?

Which method above would be most efficient?  Thanks.
