Reply To: Surface Reaction: UDF: Ansys Fluent Error – reg

[sudeepns.197me025]

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.
