Abaqus - Thermal Transfer Question

Hello to all, 

I'm a student, and I'm looking to know how to model conduction on Abaqus

To explain the context, I have an assembly of a model that I have to study in thermal, the problem is that I can not create the different interactions between the parts.

I have two parts that are glued together and two parts that have a gap between them and I don't understand how to do these simulations on Abaqus. 

Thank you for those who will help me. 
Antoine
