Winning Eleven 2002 English Version Iso Burner more. When radial fins operate in a natural convection environment, radiation heat loss is comparable to convection heat loss and must be included to simulate the surface heat loss accurately. The present model allows for combined convection and radiation heat loss from tip of the fin instead of commonly employed insulated tip or pure convective tip conditions.

I'm a new user to Comsol, having used other FE and CFD packages and I'm having difficulty with getting a test model with natural convection to run successfully. I've followed the examples in the help file which work perfectly, but any model I've built myself either gives errors before the model even starts running ('Not a number' results in various nodes in the model) or fails to converge. The test model is a heated aluminium block 30 mm x 20 mm x 1 mm high generating 1 W power, centered on the floor of a 100 mm edge cube filled with air (I know this can be done in 2D or as a quarter model, but the follow on model I want to run has no symmetry and will have the same overall boundary conditions, so getting this running would be most of the way towards the final model). The floor is insulated and has no airflow through it and the remaining boundaries of the air volume are open to flow (Walls are Inlets (I've tried with them as open boundaries too with even worse convergence), ceiling is outlet and outflow).
