My system:
Windows 7 (x64) + Fluent 14.5 (x64) + Visual Studio 2010 Professional + SDK 7.0A

Step 1: Find the console of Environment variables---My Computer->Properties->Advanced-> Environment variables

Step 2: Change or add three Environmental variables below:

I. INCLUDE (capital letters)
C:\Program Files (x86)\Microsoft Visual Studio 10.0\VC\include;C:\Program Files (x86)\Microsoft SDKs\Windows\v7.0A\Include

II. LIB (capital letters)
C:\Program Files (x86)\Microsoft Visual Studio 10.0\VC\lib\amd64;C:\Program Files (x86)\Microsoft SDKs\Windows\v7.0A\Lib\x64

III.Path (small letters)
C:\Program Files (x86)\Microsoft Visual Studio 10.0\VC\bin\amd64;C:\Program Files (x86)\Microsoft Visual Studio 10.0\Common7\IDE;C:\Program Files\ANSYS Inc\v145\fluent\ntbin\win64

Step 3: Start Fluent from "Visual Studio x64 Cross Tools Command Prompt" by just typing "fluent" in the command prompt.

Step 4: Include the correct working directory while launching Fluent from GUI.

Step 5: Compile the UDF normally: Define --> User defined --> Compiled --> etc..
Did someone try to do something similiar in Windows 8.1, 64 bit with Visual Studio 12 and the Windows Kits 8.1. Did it work?

These are my Environmental variables:

INCLUDE= C:\Program Files (x86)\Microsoft Visual Studio 12.0\VC\include;C:\Program Files (x86)\Windows Kits\8.1\Include

LIB=C:\Program Files (x86)\Microsoft Visual Studio 12.0\VC\lib\amd64;C:\Program Files (x86)\Windows Kits\8.1\Lib\winv6.3\um\x64

Path=C:\Program Files (x86)\Microsoft Visual Studio 12.0\VC\bin\amd64;C:\Program Files (x86)\Microsoft Visual Studio 12.0\Common7\IDE;C:\Program Files\ANSYS Inc\v150\fluent\ntbin\win64

Still not working for me.

Error:

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

PLEASE guys, help me!

Are you sure that these addresses are pointing to right directories?? In other words are you sure that these directories exists?

I have tried windows-8 and installed Ansys-15 without any problem. I dont remember the exact steps now. I used windows-8 for a very short time (only couple of days) and then switched to windows-7 again.

vasava,

The directories do exist. I searched for the adresses in the windows explorer and just copied them to the environmental variables.But it is not working!

Did you run Fluent from GUI or from the Windows SDK prompt?

Well I had a case with UDF (with velocity profile and viscosity model) that I could run without any problem. But I dont remember if I used SDK to start fluent.

Anyways here are steps that I followed (both installation on win-7 and 8) along with links where I downloaded files. Hope they help.

Step-1: Install visual studio 2008 from DVD.
Step-2: Install .NET 4 from Microsoft website.
Step-3: Install SDK. Download from following link.

http://download.microsoft.com/downlo...DKX_EN_DVD.iso
http://www.mydigitallife.info/window...download-link/

If your operating system language is not English then SDK may behave strangely.

Hi everybody!
I haven't been work Windows 8 so that I don't know Environmental variables in Windows 8. Now, I don't work UDF in Fluent, i have Fortran in CFX. Please!

I think these errors are due to problems with your UDF and has nothing to do with compilation.

Thanks for the reply. I tried to code the shock sensor algorithm which is attached below but getting errors like that..
Here is the code.

#include "udf.h"
#define A 340.26

DEFINE_ON_DEMAND(shock_sensor)
{
Domain *d;
Thread *t;
cell_t c;
d=Get_Domain(1);

real f_shock, velocity;
thread_loop_c(t,d)
{
begin_c_loop(c,t)
{
velocity=(C_U(c,t)+C_V(c,t));
f_shock = (velocity*C_P_G(c,t))/(A*abs(C_P_G(c,t)));

if(f_shock>=1)
{
C_UDMI(c,t,0)=f_shock;
}
}
end_c_loop(c,t)
}
}

Any help would be appreciated

Thanks in advance

I agree with vasava,The errors you are getting have nothing to do with compilation or environment variables.Some easy ones to solve are The missing ; (just add it to the end of the command in the line showed between parêntesis).Another one are the variables like 'velocity' that are being used without previous declaration.
Try to look up for threads for each error and go to the line to solve it.

Good luck!

i've just solved the problem, make sure you type all the path in the right position. If yes, go to "C:\Program Files\ANSYS Inc\v145\fluent\ntbin\win64" find a file named "udf", open it with note pad. In row 10, change the path "set MSVC_DEFAULT=%ProgramFiles(x86)%\Microsoft Visual Studio 11.0" to your current activated VS version. and i think that'll do. If no, please contact me.

Did you ever find a solution that worked for you on this issue?
(never mind, I now see the response thread)

It worked well, since I added the xcopy.exe path too.
