Dear all

I had a problem about calculate convection coefficient "h".

Because I don't know the "h" of my model, and I want to calculate the "h" by using "Fluent"

If it is possible, how should I do?

Please direct me, thanks.

I guess that you want to calculate the heat transfer coefficient at a wall surface.
You can do it from the 'Report' option in post processing.

Report > Surface Integrals
Select "Area weighted average" under report type.
Select "Temperature > Surface Heat Transfer Coef." under "Field Variable"
Select your surface and click "compute"

All this, provided you had turned on your Energy Equation, and given proper thermal boundary conditions.

Dear srjp, thank you very much.

The answer is what I need.

I just need the surface h to be used in the boundary condition of energy equation.
