In Fluent code, the UDF must be written in C ++ only; you have to see UDF manuel , there is an overview in the attachment.

There is only one language you can choose to write UDFs for Fluent. This restriction is given by the fact that it uses special macros and a built-in compiler. Other compilers probably won't work.

Therefore, you are restricted to plain C. Neither C++ nor FORTRAN will work.

In Fluent code, the UDF must be written in C only; not in C++, excuse for the mistake

Thanks all for answering.

Best regards.
