Step 1.
Write down what you want the UDF to do. Should the UDF change something? What should it be changed to?
Step 2.
Look in the manual if you can find UDFs that change the same property that you want to change.
Step 3.
Open a text editor, copy the UDF from the manual, and change it into what you want.
Step 4.
Open Fluent, compile the code. If this fails, ask here, but be sure to show the errors that you get after you pressed 'build'.
Step 5.
Attach the UDFs and run the simulation. If this gives an error, ask here, and show the error that you got.
Step 6.
Analyze results. If the results that you got are different than what you expected, ask here. But make clear what you expected, and what you got.

Good luck!
