Hi, I'm new here so, please bear with me

Compiling is a really easy first step to using UDFs in Fluent.

I highly reccomend you log on to the Ansys customer portal and download the UDF course materials. This includes a series of tutorials that introduce you to how to apply UDFs.

The first step to compiling a UDF is to make sure your .c file (your UDF code) is in the same folder as your fluent case file. in the GUI you then go to Define->user defined-> functions -> compiled. Add the file, click build, then click load.

That's all there is to compiling. but once compiled, you then have to hook the UDF in order to let fluent know where you want to use it in the calculations. hooking the UDF is again trivial, but highly dependent on the UDF - hooking instructions are included in the Fluent UDF Manual for each UDF function.

hi,
you should first install micro soft visual studio , then call fluent from its cross tools command prompt x64 if you are working with a 64bit version of fluent.
