We have an exciting announcement about badges coming in May 2025. Until then, we will temporarily stop issuing new badges for course completions and certifications. However, all completions will be recorded and fulfilled after May 2025.

Sir, As per the observation, there is no information available for UDM after the completion of 50% of the simulation. 
This indicates that the Fluent does not identify UDF for the surface reaction. 

To further clarify, I am using the Ansys 2024 R1 version and, hence, additional compiler tools, such as Visual Studio, I am not using. 

To compile the UDF, I am following these steps, If I am wrong, kindly guide me. 
1. I am sving the UDF in .c format
2. Using the Compiler command, I will import it to the fluent environment and build it, and further, I will load it. 
3. I will hook it with the argument name given in the UDF code. 
4. Initialize and run the simulation. 
5. If UDM is used, I will allocate a memory value of 10.

Please let me know, what to be done to trigger the UDF.
