I had to decouple the wall and wall:shadow boundaries. My goal was to keep the wall:shadow boundary as a coupled interface and set the wall as a heat source. However, this approach did not work as expected. When I attempted to set one boundary to a heat flux, the other would automatically change as well, limiting me to choose either temperature or heat flux for both, but not the coupled setting.

I’m not sure why Fluent enforces this behavior, preventing me from independently configuring the boundary conditions on wall and wall:shadow.
