I'm trying to simulate a heat transfer process wherein a metallic ball is heated by hot air. Since a solid sphere will have only one external boundary, how do I provide an interface for CHT and boundary conditions for the metallic sphere at the same boundary?

To do this, you will want to flag the boundary that defines the sphere as an interface boundary. Then you define the forward region (assuming normals point out) as the fluid region and the reverse region as the solid. You will be able to initialize those regions separately in initialize.in to set their conditions.


Try looking at the example case with conjugate heat transfer on the piston. You can set up your interface boundary in the way the piston is handled.
