UDF - Error loading libudf
 

Hi,

i've succesfully compiled my udf, but when i load it fluent says

The UDF library you are trying to load (libudf) is not compiled for 2ddp on the curent platform (win64).

what can i do ?

I use fluent 13, visual c++ 2008 express and win7 x64

Thank you

Hi,

Were you able to sort out this problem?

If yes, kindly please let me know how you resolved this issue.

Thank you.

Hi,

if you have not done it be sure to start Fluent from the VS command prompt.

HI, have you checked the environment settings of your computer? Make sure all the settings are correctly. I remember once there was a thread talking about how to set the computer environment for FLUENT on this forum, if you followed all the instructions in the replies above but you still could not get udf work, would you mind to search through the forums to find that thread, and reset the environment. This should work.:)

Best regards,

Hi,

Could any body resolved this problem?

I have seen many threads regarding this but yet I am not able to solve the proble.

I have installed Visual studio 2010 express and Fluent 13. Also installed "Microsoft Windows SDK v7.0".

I have run the Fluent from SDK command prompt. And yet I have recieved the error saying that

"The UDF library you are trying to load (Sedimentation) is not compiled for 2ddp on the curent platform (win64).
The system cannot find the file specified.
C: estudf\Sedimentation\win64\2ddp\libudf.dll"

Please let me know the solution for this.

Thanks in advance.

Compiling and Loading 64 bits UDF library
 

This ANSYS support note provides all informations necessary to compile UDF for FLUENT 64-bit

Hi Laurent ,


Thanks for the help.

Now it is working fine for me. I have followed same steps as mentioned in pdf file.

Probably this file is available for all the users of this forum.

Hi Laurentb

I am having the same issue, I have read the PDF but do not understand,

I am a beginner and trying to complete the tutorial "heave and pitch simulation of ship hull moving through head sea waves" and I have the hull geometry and a 6DOF UDF which is what I cannot load as it says

"The UDF library you are trying to load (libudf) is not compiled for 3ddp on the curent platform (win64).
The system cannot find the file specified."

Can you please explain in simple terms what I need to do,

Thank you in advance!

the content of the pdf file :

Compiling and Loading FLUENT 64-bit UDFs using the "FREE" Microsoft Visual Studio 2010 32-bit Express Edition and the 7.0 SDK

IMPORTANT SUPPORT NOTE

Instructions

Download the Microsoft Visual Studio Express Edition (2010) performing a default installation

7.0 SDK

Microsoft Windows SDK for Windows 7 and .NET Framework 3.5 SP1

IMPORTANT NOTE FROM MICROSOFT

This prevents an issue where some platform configuration choices are unavailable in Visual Studio’s New Project Platform and New Solution Platform dialogs.

Starting FLUENT using the SDK 7.0 Command Prompt Window

1. Open up the SDK Command Window. This is required as this will set the compiler environment variables.
2. Choose the

3. Launch FLUENT 13.x from this window. (image below):

NOTE

: Make sure the CMD window states the following

SDKs\Windows\v7.x”
b. Targeting Windows Server 2003 x64 DEBUG

c. Change to your Working directory (directory where your .cas, dat and .c file reside)

d. Launch Fluent: “C:\Program Files\ ANSYS Inc\v130\fluent\ntbin\win64\fluent”


you can find this pdf file in fluent users website.

First of all, i recommend you read the Fluent UDF Manual.

If you use a udf you will need to compile your code (.c file) in order to obtain a compiled library (.dll). You don't have to do this if someone give you the library precompiled BUT the library works only for a specific OS (32 or 64bits) and a specific solver (2d or 3d or double precision).

In your case you haven't got a library compiled for your OS (64bits) and your solver (3ddp)

sdk command prompt
 

Hi, i have visual studio 9 and in the sdk i dont see a command prompt, cant i start ufd for fluent using visual studio command prompt?

Hi,

I'm having this problem too, but my windows and the visual studio are 64bits...also I copied a udf that i knew it was right and it was compiled correctly and I succed to load the library. My own codes, on the other hand, i cant compile nor load the library.....

This can't be a system problem, right?
What am i doing wrong?
I'm new at udf.....

please help me

Hi, i use fluent 14, cfree4_1_pro and win7 x64
i've succesfully compiled my udf, but when i load it fluent says:
