Hi,
I have a simple test, a cube 1*1*0,2 (l*l*x). Boundary condition T1=350°K in upper face, T2=300°k in opposite face, k=200. So Q=k/x*A*(T1T2)=50000 Fluent report flux no problem, Q=50000 as formula, but I want to export heattransfercoefficient for every cells. he must be 1000, but fluent calculate 1.2194E+003. Why? For this case I insert only 1 cell mesh.

Yes, in simple case. But when I have a complex structure whit fins?
Goal is to understand how fluent calculate this rate or I can calculate this from ''fluentexport''. So I can tell: this is average of structure from report flux. That is report flux=Q, U=Q/A/(T1T2). From mesh I can calculate every single Q(i) by cells, so I can compare average with single station to see the difference and if this difference is high. Imagine a structure like this:
