Open boundary conditions of natural convection in 2D heated vertical channel

LiLAJ · September 4, 2023, 11:09

Hi buddies,
How can i apply the sets of boundary conditions in FLUENT for getting a recirculation zone at outlet of channel.
I wonder if i can use UDF code, if yes where could I find it ? or there is another way,

That BCs are applied in following article:
Benchmark solutions for natural convection flows in vertical channels submitted to different open boundary conditions.
Thanks

Inlet velocity gradient equals zero.
The problem how can i define the velocity in this case?
