To add thermal contact:
1. Right-click “Heat Transfer in Solids 1” node and select “Pair Thermal Contact” from Pairs boundary conditions option to add “Pair Thermal Contact" node
2. Left-click “Pair Thermal Contact 1” node and go to Pair settings window for Thermal Contact. Find Pair Selection section and click “Contact Pair 1” to make boundary selection
3. Find “Contact Surface Properties”/”Contact pressure” section and change default “User defined” to “Contact pressure, contact pair p1 (solid/cnt1)” (this is coupling between thermal contact and structural contact)
4. Adjust other parameters in the “Contact Surface Properties” as needed

1. You can use contact pressure variable “solid.Tn_p1” to calculate contact surface area:
contact_area=intop1(solid.Tn_p1>=0)
where intop1() is boundary integration operator over contact surface.
2. Default sub-node “Thermal Insulation 1” means that there are no other thermal fluxes between contact pair surfaces other then defined in the parent “Pair Thermal Contact 1” node. You can override default “Thermal Insulation 1” sub-node to include other heat fluxes between contact pair surfaces such as Surface-to-Surface radiation, for example.
