1. Create area averaged report(s) of heat transfer coef field function on the surface(s)

2. Create new field function(s) called Nusselt # and define is as per its formula using the field function(s) created by the above report(s), fluid conductivity and char. length

3. Create new 'max' report with N# as the field function and run this report.

Ping This was very helpful: In CCM+ there is a field fucntion of Nusttle number. Averaging it directly would give the same result, I assume. Waseem
