Why do you expect the water to be 80-90C if the wafer is 65C?

Well there are in person experiments going on but the conditions are different the heat source is not the wafer but an external light. Giving it an actual second thought my temperature range of 80-90C is an overestimate, it would probably be closer to 50C maybe... I wrote a longer explanation but the page reloaded and it was deleted so let me know if this is fine. 

Are there multiple phase or fluids where we need to keep track of the interface between them? 

The container itself is not filled to the top with water. It'll be about 65% water and the rest air. I would like to see the convective heat transfer between the water and air. 

The solid will not have to have such a fine mesh as the fluid domain as it is only solving conduction here.

Makes sense but is it that important that the fineness of the mesh is different between solid and fluid bodies or is it just for processing sake?

To me, the first place I would look would be the temperature field.

So the temperature field is different than the temperature contours? 

work through the exhaust manifold tutorial. Don't focus on the meshing part (unless you plan on using Fluent meshing), but understand the basics of setting up the model and the theory behind why we chose what we chose.

Will do, I'm glad you guys go over the theory lots of tutorials don't actually explain why they chose x option. I actually only ever mesh in Fluent meshing, it seems the easiest since it's the next cell after geometry. 

Thanks again.
