i have a vertical and horizontal perpendicular plate connected with bolt,

1) at interface (contact surfaces)created surface by create from faces, (this surface helps to give resistance and conductance value)
2)when i made all parts to be a 1 part 3 bodies in DM, i can't see the surfaces created at interface in mesh tool,
5)if i make 1 part 3 bodies and topology is imprint, giving the surfaces and bodies error.
6)when i do 3 parts 3 bodies and shared topology operation i could see them in mesh tool and we performed mesh operation, and named all the walls and after i enter into the fluent i could't see the 1 surfaces which we need to control this surfaces in BC.
simple geometry trying to simulate heat transfer b/w bolted plate
