Since Fluent 18.0 it is possible to use C++ code in a User-Defined Function (UDF). When compiling the source code from within Fluent, it sets the compiler flags automatically based on the file extension. When the source files have the file extension *.cpp the flags are set for C++. When the file extension is just *.c it uses flags for C99. The supported C++ standard depends on the used compiler and can not be influenced from within Fluent when using gcc on Linux or Visual Studio on Windows.
