Help needed for extracting Heat Flux from Fluent

July 10, 2006, 10:50

Hello everybody,

I am a user of Fluent v6.2, and I have a problem with writing UDF for 2D case.

In the case I am calculating I have a small pipe, and I need to know the heat flux around the tube.

I am trying to get from FLUENT value of "Total Surface Heat Flux" through the wall, but unfortunately I cannot find the option how to do that. I do not have problems with getting other values (for example Temperature, which I also need).

Maybe some of you had already problem like that and could help. Or maybe there is another way to calculate the heat flux, based on for example enthalpy.

Thank you in advance for your help.

What about using the Report->Fluxes tab with heat transfer checked off?
