Thin domain

Hi, how do I insert a thin domain between two solids? I think it is in the meshing. I modelled it as one part with two bodies, if that makes a difference. Thanks for your help

Basically I have two fluids, one hot and one cold, and I want to do a fluid-solid interface between them. I can get the fluid fluid interface, but if I try to do a fluid-solid, it says no valid domains. So I think I need to put a thin domain between them so I can do the heat transfer of a thin material. What am I missing out? Thanks

Do a fluid fluid interface and you can put a thermal resistance on the interface, to model a thin solid between two fluid regions.
