How to simulate heat transfer in Solidworks Simulation (Premium)?

Hi all,


I have an assembly in Solidworks 2010, and I am trying to simulate heat transfer throughout the component using the Simulation tool.  Basically, I want to heat the top of the component at 210 C and then allow heat to flow through the component and then radiate to the external atmosphere (say at 25 C).  I am doing this in order to see how long it takes for other parts of the assembly to reach a desired target temp (say 100 C).


Right now, I have defined a Thermal Study in Solidworks Simulation, and applied several thermal loads.  I defined the Initial Temperature of all exposed faces to be room temperature (25 C), and then defined the Temperature of the top face to be 210 C.  I also have a Radiation load (surface to ambient) that specifies that all exposed faces radiate to the ambient 25 C atmosphere.  However when I make a mesh and run the thermal study, the results do not seem entire assembly reaches 210 C within 100 seconds (which seems unrealistically quick) and no heat seems to dissipate to the atmosphere.  Any thoughts on what I am doing wrong or defining incorrectly?
