compiling udf on windows7 64-bit
 

i tried to compile a udf on winx64,i did nearlly everything that was out there but nothing seemd to work for me,i kept getting the"Error:The UDF library you are trying to load (libudf) is not compiled for 2ddp on the current platform (win64)" when i run fluent using visual studio x64 command prompt i had this error: win SDk Dir not found,and using the windows7 SDK cmd shell i had this error:the x64 compilers are not currently installed. after a whole week working on it finallay i found the solution heres what you need and what you should do:
my softwares:Ansys fluent15.0(64bit),Microsoft windows7 SDK.Net framework4.0,visual studio 10 ultimate,VC++ 10 express
set your variables as:
(control panel-->system-->advanced system settings-->environment variables-->system variables-->add)
name:Include
value:
:\Program Files\Microsoft SDKs\Windows\v7.1\Include;C:\Program Files (x86)\Microsoft Visual Studio10.0\VC\atlmfc\include;C:\Program Files (x86)\Microsoft Visual Studio 10.0\VC\include
name:Lib
value:C:\Program Files\Microsoft SDKs\Windows\v7.1\Lib\x64;C:\Program Files (x86)\Microsoft Visual Studio 10.0\VC\atlmfc\lib;C:\Program Files (x86)\Microsoft Visual Studio 10.0\VC\lib
name:Libpath
value: C:\Windows\Microsoft.NET\Framework64\v4.30319;C:\W indo ws\Microsoft.NET\Framework64\v2.0.50727;C:\Program Files (x86)\Microsoft Visual Studio 10.0\VC\atlmfc\lib;C:\Program Files (x86)\Microsoft Visual Studio 10.0\VC\lib
this the important one
name:path
value:C:\Program Files\ANSYS Inc\v150\fluent\ntbin\win64;C:\Program Files (x86)\Microsoft Visual Studio 10.0\VC\bin;C:\Windows\Microsoft.NET\Framework64\v 4 .30319;C:\Windows\Microsoft.NET\Framework64\v2.0.5 0727 ;C:\Program Files (x86)\Microsoft Visual Studio 10.0\VC\vcpackages;C:\Program Files (x86)\Microsoft Visual Studio 10.0\Common7\IDE;C:\Program Files (x86)\Microsoft Visual Studio 10.0\Common7\Tools;C:\Program Files\Microsoft SDKs\Windows\v7.1\Bin\x64;C:\Program Files\Microsoft SDKs\Windows\v7.1\Bin;"C:\Windows\System32"
the red one is the whole solution
after setting your environment variables run fluent from SDK cmd shell:
start-->all programs-->microsoft windows SDK v7.1-->windows SDK 7.1 command prompt
then go to your working directory where your cas and c files are then copy the address of your working directory for example my working directory is (C:\Users\edi\Desktop\kkk)
in command prompt type:cd (right click and paste your working directory address) for example:cd C:\Users\edi\Desktop\kkk
press enter then type fluent then press enter
after that read your mesh file and compile your udf
cheers

Hi, I also was trying with this modification and adding the same variables:
name:Include
value:c:\Program Files\Microsoft SDKs\Windows\v7.1\Include;C:\Program Files (x86)\Microsoft Visual Studio10.0\VC\atlmfc\Include;C:\Program Files (x86)\Microsoft Visual Studio 10.0\VC\Include
name:Lib
value:C:\Program Files\Microsoft SDKs\Windows\v7.1\Lib\x64;C:\Program Files (x86)\Microsoft Visual Studio 10.0\VC\atlmfc\lib;C:\Program Files (x86)\Microsoft Visual Studio 10.0\VC\lib
name:Libpath
value: C:\Windows\Microsoft.NET\Framework64\v4.0.30319;C:\Windows\Microsoft.NET\Framework64\v2.0.5 0727;C:\Program Files (x86)\Microsoft Visual Studio 10.0\VC\atlmfc\lib;C:\Program Files (x86)\Microsoft Visual Studio 10.0\VC\lib

name: path
value:C:\Program Files\ANSYS Inc\v150\fluent\ntbin\win64;C:\Program Files (x86)\Microsoft Visual Studio 10.0\VC\bin;C:\Windows\Microsoft.NET\Framework64\v 4.0.30319;C:\Windows\Microsoft.NET\Framework64\v2. 0.5 0727 ;C:\Program Files (x86)\Microsoft Visual Studio 10.0\VC\vcpackages;C:\Program Files (x86)\Microsoft Visual Studio 10.0\Common7\IDE;C:\Program Files (x86)\Microsoft Visual Studio 10.0\Common7\Tools;C:\Program Files\Microsoft SDKs\Windows\v7.1\Bin\x64;C:\Program Files\Microsoft SDKs\Windows\v7.1\Bin;"C:\Windows\System32"

Are you sure that the last part is correct? Probably it should be ;C:<working directory> not the "C:\Windows\System32"

Thanks

I'm positive

Awesome, thanks! I've spent ages trying to get parallel compiling working in Windows 7 64 bit with ansys 15. I've done so many things I'm not exactly sure which ones are necessary, but I used all your environment variables, modified to work with Visual Studio 12 and SDK v7.0 instead of v7.1, I couldn't find and folders labelled "atlmfc" so I left those out but it worked fine anyway.

For people having similar issues, I also followed this (in addition to adding all the environment variables mentioned here)
http://www.simutechgroup.com/CFD/com...5-or-15-0.html

With the slight modification that I ran fluent through the "Microsoft Windows SDK v7.0" command prompt rather than the Visual Studio one.

Now I just have to figure out how to write my UDF to do what I want, but at least it's compiling now!

Where is the place for adding the variables?
User variables or System variables...

system variables

I've make my environment variable like yours,, but when i'm trying to compile my udf, i've got this error message :


Copied G:\udf.c to libudf\src
(system "copy "C:\PROGRA~1\ANSYSI~1\v140\fluent"\fluent14.0.0\sr c\makefile_nt.udf "libudf\win64\3ddp\makefile" ")

What should I do???

Hi ad,

Thanks for your solution. It worked perfectly for me after struggling with it for a long time. Now I can compile udf with parallel processing. My only concern is that now I have to run fluent through SDK command prompt. Is there anyway I can compile udf in parallel while I start Fluent from workbench?

I think you should do the following:when you run the fluent from the workbench and the fluent panel opens you choose parallel for processing options and then you just do the usual thing for compiling.
Define---->User-Defined---->Functions----->Compiled

It is not that simple. I have already tried this. When I run the fluent from workbench and compile the udf, I will get this erro:

LINK : fatal error LNK1104: cannot open file 'kernel32.lib'

But if I run fluent from SDk, I can run fluent in parallel with no problem.
