Hello Dears

I have the following case:

In this case, all the walls are insulated except the outer surface of the obstacle , where a constant heat flux is applied. Air(300 Kelvin) is used as a working fluid and crosses over the heated obstacle.
I meshed the heated object, because there is a conduction inside that. Moreover, I meshed inside of the 2D channel for air crossing inside.
After importing the mesh file in Fluent, "shadow wall" is added in the Boundary condition.

What should I define the boundary condition for "water-solid interface wall(inner surface of heated object)"and "shadow wall"?

Any help would be appreciated .

Thank you

Shayan
