Reply To: Application of convective heat transfer coefficient equation in CFD-Post

[Rob]

There is no heat flux on a plane surface in a fluid zone. Heat flux is through something - you only have temperature data. This is why planning post processing before building a model is important. Adding bands or similar to the wall would make this trivial as we can report the flux directly in Fluent, along with various temperatures assuming the built in htc functions weren't suitable. 

CFD Post was recommened for Fluent for a few versions but Fluent's post processing is (for the most part) now much better: for numerical data I'd always use Fluent's output.
