ANSYS Fluent R3 Compiler Error Issue Fix (UDF Library not Compiled for Parallel use)

Make sure that Visual Studio is installed before using this fix. This video is not meant to solve everyone's issue. I am just sharing my personal experience if it does not work please do not blame me for not solving your problem.

I installed many versions of VS but it seems like the older 2012 version works the best

This totally works; you are a lifesaver.

This totally works, worth trying. Thanks

when I open cross tools command, I get this message:

'C:\Program' is not recognized as an internal or external command,
operable program or batch file.

I wonder if you have an idea what is it saying about?

[marcelk]

It's also worth to reinstall Ansys - and install it on your default folder - it worked for me

Can i use command prompt ?. I can't find x86 cross tools although i have installed VS 2019

When I load the file I see the error message in v182 version

Great video, unfortunately I haven't reach compilation, when I open cross tool command VS2019 it opens and the first line says something like "not expected \ Microsoft at this time" not as it says in your window. Maybe do you have idea about how to set correctly Visual studio, i guess is something about path - environment variables. I have tried to configure but not results.
Thanks so much for your help

Hi, which workload is to be selected while installing VS for Fluent?

[abhijithm]

Thanks for the video. I have installed Visual Studio 2017 on my system but the X86 cross tool command prompt is not getting installed by default. Is there a specific way to install it ?

[ayahkhalid]

Thank you so much! This helped a lot you have no idea! Bless you

Hello, thanks for the video. I am able to compile the UDF into the case via cross tool command. I want to know if it is possible to import the case with loaded UDF back into Workbench again to run parametric study? Because once I load the case into fluent in workbench, then the same error shows up and the cycle repeats.

If not I will have to redo the same case with different input via cross tool command multiple times.

I followed the steps, but still I am getting that error...😔

[shashidharreddy]

How to do this if I installed ansys in D drive?

[AsadRehmanism]

Hey! i get error message when i read case file that reads "Error: File has wrong dimensions (2).
Error Object: #f

Error: Error reading

Error Object: #f"
May be this is the reason udf build is still giving error. Any help???

[fluidos]

I have followed the same steps as you described here but still the same error occurring. please help

[fero]

Is there any option without visual studio ?

[alvinante]

did not work for me also, should I set parallel in fluent set up before I save the case file?? thank u
