Hi all! I wonder if it possible to compile a UDF using g++ instead of gcc. I tried to change in the makefile the option CC=cc to CC=g++ but when I compile it gives me some errors related to fluent udf.h file. So the question is: since I have an external library written in C++ how can I link it to my udf which must be written ( I suppose) only in C?Luca

you must compile your C code (not C++). So, you must be sure that you C code is contained in the same folder that your case and date files.

If you are sure about this, you should review the environmental variables on:

control panel/system/advanced options/environmental variables

Here you must write the direction of v1.1 file (this file is contained in program files/C++ files). Click accept, accept and apply.

The last way to compile your UDF is open the VisualC++ toolkit file and run Fluent since here.

Next to it, you can comiple satisfactory your UDF.

I hope that it help you.

Hi, I have a C++ code and I will combine this code with UDF. Can anyone help me which commands in UDF will use for combining C++ code? Thank you very much

As I remember and like Alex said, Fluent understand only C and not C++.

The compilers which work with Fluent are listed on www.fluent.com and in the Fluent manual.

Dear Alex, thank you for your answer. I have no problem in compiling a UDF written in C. I just wanted to compiled a UDF using a C++ compiler. I can compile my UDF using Visual C or gcc but if I try to compile it as it were written in C++, there are some problems related to how Fluent files are defined. Luca

dear Luca, I don't know about the solution of your problem, but if I research something about, I inmediately will send a message ok?

Thank you Alex! Anyway no problem. I thought of creating a stand alone application written in C++ which is called by my UDF though the operative system. Luca

hi,

I heard that a Chinese guy wrote a code to compile the UDF using C++. You can contact him. His name is Peng Huang. email: huangpeng8@163.com

Good luck. Owet
