Reply To: How to Model Outlet Heat Reduction using UDF

[SRP]

HI,

I suggest you to check fluent customization manual: Chapter 1: Overview of User-Defined Functions (UDFs) (ansys.com)

To simulate the effect of the reduced temperature on NOx formation,you may be able to modify the reaction rates based on temperature changes. This can be complex and may require additional UDFs.

Hope this helps you.
