How to get the heat flux of an interior boundary?
 

My model contains two regions, and I need to know the value of heat flux of the interface between this two regions, how can I get it?

Hi,

Nobody can do it via any UDFs although mass flux is OK.
In Fluent, once iteration is done, the value is thrown out.

hi,

HVAC:
is that true even if you issue the command:

solve/set/expert

and then answer yes when it asks to free temporary memory??

Hi,

'solve/set/expert' setting is for gradient macros(eg., C_T_G or something like that).
So even if this setting is done, we can't get heat flux.

Also you can post process the value of source terms, residuals etc. :cool:
