solar driven natural convection

      Physical model: The model is of a solar chimney. Essentially it is a flat, vertical solar collector with input pipes. As the air in the collector is heated it rises and exits out the top of the collector, drawing in ambient outdoor air from the input pipes. 

      Fluent stuff: So far I've been trying to model this using solar ray tracing. I'm wondering if anything special needs to happen with the boundary conditions to make it work? I've been playing around with them but can't get the residuals low enough. 


       


      Thanks!

      Natural convection can be transient, so you may need to use the transient solver, or just accept less good results.  As for the other settings, please add images for comment.
