Recirculation UDF
 
Hi,

Does anyone have a recirculation Fluent UDF written they can share? I know this is openly available in Icepak (just by canceling a solve and checking the two recirculation boundary conditions).

Please post in this thread if you have it.

Thanks.

Enter following commands in TUI:
(rpsetvar 'icepak? #t)
(models-changed)

Two boundary conditions are added:
Recirculation-Outlet and Recirculation-Inlet

The alternative of writing the UDF uses DEFINE_ADJUST and you can read about this in the Fluent User Manual.
