How to add Variable Wall Temperature Boundary Condition in ANSYS FLUENT ?
 

I want to spatially vary the temperature along the wall (While assigning Boundary Conditions, I Need to add Non Isothermal Boundary Condtion), I mean at every cell , the temperature should vary along the profile (wall).

Thank You

You can do that using UDF, there is an example of it in the Fluent UDF User Guide.
If you have ANSYS 2019 R1 or R3, you may use Expressions option of ANSYS Fluent.

You can also just make a PROFILE
It's also one of the tutorials

You can use the following methods to create a spatially (and/or temporally) varying temperature boundary condition. Listed in order of increasing difficulty.

1. Import a profile. Easy to do if you already have appropriate data for temperature in an xyz format.
2. Use an expression. Need to know a little Python but easy to parameterize and deploy. Mildly more work than a profile.
3. Use an UDF. Significantly more difficult.

Can You Help Me out with A Sample UDF (JUST THE FORMAT) for Variable Wall Temperature Boundary Conditions?
