      As already highlighted by mli You need to attend a UDF Training so that you get the Training Materials. For the Function itself a DEFINE_PROFILE is required to prescribe the profile at inlet.

      Hi,


      The old course is available on the Customer Portal (the University ASC will have access) or for the more recent version you will need to subscribe to the ANSYS Learning Hub. Details are here  https://www.ansys.com/services/learning-hub


      However, if you read all the answers in all the threads you've created you will find the manual covers most of what you need, via DEFINE_PROFILE. 


      Best wishes,
      Rob

      Hello,


      As indicated by Rob, you should be able to find all the necessary information you need in the UDF customization manual. If you are looking for sound advice, I strongly recommend that you copy the UDF from the manual and test it to see for yourself how it works. Once you have confidence in the original UDF, you can start working on modifying it. This exercise will make sure you are able to run and compile UDFs at your end on your fluent installation. Here is a link on how to run your UDF. i hope this helps you to move forward with your analysis.



      Best Regards,


      Karthik
