Hi,

I am a new user of FLUENT. I am required to do a 3D simulation a immersing a box into the sea.

For testing sake, I have came out with a UDF code for a 3d inlet velocity profile with wave motion in the x-direction with a moving object in the water.
For modelling, I built a small box and a big box encasing it, hoping to be able to simulate the dropping of the small box into the waters (2 phase fluid in the big box). The model was a 3D model.

However, I have encountered this error "The UDF library you are trying to load is not compiled for 3D on the current platform (win64). \libudf\win64\3d\libudf.dll"

Could anyone tell me what went wrong? Would really appreciate it!

Thank you

Hello,
this is my first time on this forum,
please, forgive my ignorance and my poor English.
my problem is basically the same as kailingkk
The question that I propose has already been addressed, I read and followed the discussions but have not been able to solve the problem.
I'm trying to perform an application / tutorial "heave and pitch simulation of ship hull moving through head sea waves."
I Use ansys 14.5 on windows 8 with Visual Sudio 2012,
and are also installed Visual C++ 2005 2008 2010 (all x64)
The problem concerns the Compiled UDFs.
In the tutorial I provided the mesh, the source file (six_dof_property.c) and some case and data.
I put everything in a folder ( C:\Users\giuseppe\Desktop\ansys fluent ship motions)
I load fluent and follow the instructions.
3D, double precision and set the working directory:
C:\Users\giuseppe\Desktop\ansys fluent ship motions (the same of .c)
Read mesh
Set the models file (multiphase and viscous)
Define >> user-defined >> function >> compiled
In the source file add the .c file and build the libduf (defoult librery name)
In the same folder of .c is create the folder libduf
But in the Console messages me an error

Copied C:\Users\giuseppe\Desktop\ansys fluent ship motions/C:\Users\giuseppe\Desktop\ansys fluent ship motions\six_dof_property.c to libudf\src
udf_names.c file in 3ddp is upto date.
(system "copy "C:\Program Files\ANSYS Inc\v145\fluent"\fluent14.5.0\src\makefile_nt.udf "libudf\win64\3ddp\makefile" ")
1 file copiati.
(chdir "libudf")()
(chdir "win64\3ddp")()
"nmake" non Š riconosciuto come comando interno o esterno,
un programma eseguibile o un file batch.
(("nmake" Š not recognized as an internal or external command,
operable program or batch file.))
Done.

And if load:

Opening library "C:\Users\giuseppe\Desktop\ansys fluent ship motions\libudf"...
Error: The UDF library you are trying to load (libudf) is not compiled for 3ddp on the current platform (win64).
Impossibile trovare il file specificato. ((Can not find the file specified.))
C:\Users\giuseppe\Desktop\ansys fluent ship motions\libudf\win64\3ddp\libudf.dll
Error Object: #f

Why?
where is the error ?
thank you

Did you try the SDK for compiling UDF?

[DartPeppe]

solution found!
I used VS2012 x64 cross tools command prompt for launch Fluent
is now in run calculation and it seems that is going well ... i tell you if there are problems ...
note: the windows software developement kit for windows8 is installed, probably SDK compiling automatically UDF if i start Fluent from VS command prompt...right?
thanks

Hi, I am still very much stuck with my UDF code. Would really appreciate it if anybody could take a look at my attached c file and tell me what went wrong!

[andrei110726]

I am telling you follow these steps and very easy to set up


install MSVC 2010 Express edition

install windows sdk7.1

and load fluent from sdk command prompt by navigating to you file location

and type the casename.cas

it worked for me after spending 4 fucking days......


take care lads

[Isitv2A]

only two and a half day on it but still no solution ...



i install Visual studio 2010 than 2013 on my computer as well as SDK 7.0 .i run fluent from cmd shell and compiled but still this error :

The UDF library you are trying to load (libudf) is not compiled for 3d on the current platform (win64).
Le fichier spécifié est introuvable.

hello,

can anyone send me the six_dof_property.c file mentioned in the ship hull tutorial for fluent.

thanks and regards,
Prasanna Ramanathan

[nTTs]

If anyone still has them, can I have the files needed for the heave tutorial please? My email is kinsasa04@gmail.com. Thank you in advance.

Hi, Prasanna Ramanathan

Did you receive any reply regarding the six_dof_property.c file?
Mind sharing it?
Thanks
