Unable to load UDF in Ansys Fluent.

      I was trying to use a udf for a fluent simulation, I added it, clicked on build, the console showed "done", then I clicked on load and this error message came up:


       


      The UDF library you are trying to load (cdf) is not compiled for parallel use on the current platform (win64).


       


      The system cannot find the file specified.


       


       


      C:UsersrohanDesktopbtp1_filesdp0FLUFluentcdfwin642d_hostlibudf.dll


       


       


      What should I do? Please help me with this problem!

      I am also facing the exact same issue.

      When you do the compiler stage read what Fluent tells you very carefully. I suspect there's an nmake complaint in there.

      Recompile the code and see what that tells you: the error you've posted confirms the code didn't compile. When you compile there will be some warnings/errors that should explain why. n
