Guys,
I think title of the thread is clear that what's my question.

What compilers can we use in Ansys Fluent to compile our UDF?
I read something about compiling UDF e.g.:


https://www.sharcnet.ca/Software/Ans...compilers.html


But for Windows OS they just talk about Microsoft visual studio. I'm using Ansys 19 and my OS is windows. Can I use other compilers? for example GCC?

The answer is YES. However you might need to manually write your own Makefile or build the dynamic library by hand. Believe it or not, it is not worth it. It is much easier to work under *nix, rather than mock the process in win*.

And I agree with blackmask. It is possible to use other compilers in Windows, but if you have to ask this question, you will need a lot of help to set everything up so that it really works, and it is much easier to just use the (freely available) Microsoft compiler.

I have developed a tool to convert the default Fluent compiler from VC to GCC. Here the allowed attachment size is too small. Contact me if you need.

Thank you,
I wanted to use another compiler because VS is huge and take much space of the memory. May I know what compiler do you use? how do you set it up?

From the post that you replied to:

So on behalf of gearboy I can say: yes, you may know that the new compiler is GCC.

Right, we recommend tdm-gcc 4.9.2. After conversion of the compiling environment, you can compile udf same way as VC compiler.

Thank you,
You have a PM from me. I use Ansys 19, Did you chack your tool to know if it has any problem with higher version of Ansys?

Sorry for bouble post but just wanted to ask Did you check the last version of tdm-gcc? Isn't there any problem if I get the last version? currently the last version is 5.1.0.2

Please give me some time to upgrade it to support fluent19.0. Currently, it only support up to 18.2. For TDM-GCC, we recommend you use 4.9.2 and do not check server for upgrading when installing. Other versions may not work. Anyway, you can try the lastest TDM-GCC version and tell me if it works.

How much it will take time?
waiting to recieve it.

We have upgraded UdfMinGW to version 19.2, which support fluent 6.3-19.2. Please read the manual in the zip package first.

Thank you.
I uploaded the file in somewhere eles for other fellas because I had problem to download it(not good server).


http://www.mediafire.com/file/72tljt...W19.2.zip/file


I tried everything that you said and it worked very well. A screenshot





Thank you so much.


I have a question:


If we have a workbench project and there is a fluent project in our workbench, how we have to use this program?

I guess you have to add C:\TDM-GCC-64\bin to PATH environment variable first (say your GCC installing folder is C:\TDM-GCC-64).

You guess? Could you please add more details about your approach here? or maybe it could be better to check it at first and inform us because you know what's going on in this tool.


And a suggestion,
I don't know if you want to release your program as an open source project but you can use github.com

gearboy,
I'm trying to compile a UDF but get this error:




The error:

Copied F:\RDE\Rotating Detonation Engines- UDF.c to libudf\src user_nt.udf file is outdated. So, recreating the file for 2ddp ...
(chdir "libudf\win64\2ddp")nmake: Nothing to be done for 'clean'.

(chdir "libudf")(chdir "win64\2ddp")nmake: *** No rule to make target '../../src/Rotating', needed by 'Rotating'. Stop.


Done.

What's the matter with it?

[Roh]

Solved the problem and got a new error and have fallen in a new problem. Here is the new error:

Error: received a fatal signal (Segmentation fault).

Error: received a fatal signal (Segmentation fault).

I managed to compile and load the UDF. Here is the report that I got after compilation:

Done.

The UDF is compiled and loaded successfully but when I want to initialize the project I got that error.

Hi friend, I have fluent 6.3.26 on Windows 10, I prove a lot of times compiled my udf, but I think that is impossible ... I prove with VS 19, VS 17, VS Express 12... What is the correct? If you can give me another option I´ve really been enjoying that.

Thanks in advance,

Eng. Juan Antonio Blanco

Out of curiosity: why Fluent 6? That is like ten years old... You are missing out on a lot of updates! Compiler support has improved a lot since that version!
