Problems with hooking UDF
 

Hello,
I cant seem to hook my UDF onto my model, I can interept my code into Fluent with no problems but when trying to hook my UDF then my source terms do not appear as extra options and when I do hook any of the functions then I get a ACCESS_VIOLATION error.
Does anyone know why my source terms would not be available for hooking?
Thanks for any help

try compiling your UDF to see if there are any errors. if not check whether U r using the correct macros/header files
