Compiled UDF not showing up in Fluent?

el123 · November 16, 2020, 13:06

I have successfully compiled the UDF in Fluent and the 'libudf' library was successfully created (build and load both with no errors) however when I try to apply the UDF to the cell zones it doesn't show up in the drop down box?

I have checked in the dynamic mesh section too and the UDF doesn't show up in the drop down boxes there either.

Unsure where the problem is because there was no errors in the build and loading when compiling the UDF. I've attached a picture of the problem (ignore the very coarse mesh lol).

Does anyone please have any solutions to this? Haven't seen this issue anywhere!

Extra info:

The libudf library has been saved to where the udf .c file is saved and the case files for my project are saved.

The udf uses DEFINE_TRANSIENT_PROFILE returning theta_dot to change the pitch angle (theta) of blades as they rotate about an axis.

What makes you say that compilation was successful?

I'm not saying you are wrong, but I have seen too many questions here where it was said the compilation gave no errors, and then it turned out that the compilation gave errors, the user just did not know where to look for them...

Ah by no errors I meant in the fluent console window there are no errors showing (as that's what I was having issues with previously). Where would I find the compiler errors?

You are correct in looking in the console window.

press BUILD button, copy console output here

press LOAD button, copy console output here
once you are pressing load, fluent shows you the list of functions defined in your UDF
