I cant. You are the only one who knows the orientation of your model. All you have to do is change the following line to match your requirements:

F_PROFILE(f, thread, position) = (tmin+tmax)/2.0 +...

I have no idea why you get this message during interpretation of the UDF. What transient scheme do you use? Which kind of solver?

About the contour: provided the range is from 298K to 323K and the...

The code remains valid in this case. But as always, you should check if the temperature profile is correct before running your actual simulations.
No need to give me credits in your report for just...

Without a coordinate system, this image doesnt add much information.
Did you at least try the UDF i proposed 4 posts ago? Just change x[1] if the y-axis is not the direction in which the temperature...

Since you refuse to be more descriptive, I have to make some assumptions ;)
With "degrees" you mean °C, so I change the temperature variation from 298K-323K.
The x-axis coincides with the axis of...

"Linearly varying" with respect to which variable?
Could you make a small sketch of what you need?

Did you try to put both UDFs in one text file?

Then when interpreting the file, both UDFs should be available.

Glad I could help.
Lets take a look at your further questions.

x[ND_ND] is an array of dimension 2 if you are running the 2D solver and dimension 3 if you are running the 3D solver (which is...

I guess that the problem arises from the °C/K difference.

Fluent expects the output of UDFs to be in SI-Units. Therefore, the output of the UDF is interpreted as a Temperature between 21 and 23 K....

Wait a minute: When does the error occur?
When you try to interpret/compile your UDF or during the solution process?
What are the possible values y can have, i.e. what is the physical extent of the...

Which formula describes your function? Without knowing what you put instead of the "..." in

F_PROFILE(f, thread, position) = ...;

no one can guess what is causing the error.
