Hello everyone,

I am implementing UDF to Ansys Fluent 13.0 version in Window XP 32 bit. I am getting the following error.

Error: The UDF library you are trying to load (libudf) is not compiled for 3ddp on the curent platform (ntx86).

The system cannot find the file specified.

Done.

Moreover, during compilation I am getting following message in log file:

Microsoft (R) 32-bit C/C++ Optimizing Compiler Version 14.00.50727.42 for 80x86
Copyright (C) Microsoft Corporation. All rights reserved.

NMAKE : U1077: '"C:\Program Files\Microsoft Visual Studio 8\VC\BIN\cl.EXE"' : return code '0x2'
Stop.

Please can any one give some suggestions in this matter ?

With best regards,

How did you start Fluent? From the terminal?

This sounds like you a) did not install the correct Visual Studio / SDK or b) did not start Fluent from the SDK terminal.

[Yogini]

Thank you for quick reply,

I have tested to start fluent from both way: (i) simple double click on shortcut and (ii) with SDK. But I got same error.

But I am not sure for my visual Studio version. I am working with MS visual studio 8. Can you suggest which version of it, is appropriate for Ansys Fluent 13.0 on Window XP 32 bit ?

Moreover, is there any issues related environment variable setting for Ansys and Visual Studio ?

Best regards,
Yogini

I had the same problem and tried 100 things before it worked. Unfortunately, I can't remember what did the trick. But if I recall correctly, you need to install the Visual studio SDK (!) and start workbench or Fluent from the SDK terminal, not the MS visual studio terminal. Maybe I am wrong...
If this doesn't work: I think I found some help in old forum threads or in Ansys customer portal.

[Yogini]

Ok, I will try with Visual studio SDK.

I think the main problem is that you copied source code of UDF directly from the PDF manual, so it contains non-ASCII characters. You can get rid of them e.g. by uploading your code to http://pastebin.com/ and then downloading it.

Hello,
I don't know, how to use pastebin. Can you explain a bit?

[RodriguezFatz]

Copy the code to windows Notepad and than save it into some new file.
