I got the following error while compiling my udf. The same udf had compiled fine on another machine. But on the ME lab machines, it is not compiling. WHY IS THAT ?

Done.

Opening library "libudf"... Error: open_udf_library: The system cannot find the file specified.

Error Object: ()

The message


'nmake' is not recognized as an internal or external command, operable program or batch file.


tells you that you do not have the Microsoft Visual C++ compiler installed, or it's directory is not in your system PATH.

Hi

Hello ap,

Even I am facing the same problem. Can u tell me how we can specify the path to Visual studio?

Regards Karthick

Try this You need to follow the following steps 1) set up the environmental variable This is done by going to the start menu > Programs>Fluent> Set_environment clicking this would set the path and variable. 2) set up a directory structure as follows create a dir libudf in that create "src" and "ntx86". In ntx86 create "3d".( am asuming that ur simulation is 3d) 3) copy the udf (.C file) and the required header( u can get the header files frm c:\FLUENT.INC\fluent6.*.*\ntx86\src) files into the "src" folder. 4) go to c:\FLUENT.INC\fluent6.*.*\ntx86\3d copy the contents into the 3d folder which you created. 5) go to c:\FLUENT.INC\fluent6.*.*\ntx86\src copy makefile_nt.udf and user_nt.udf to your 3d folder 6) rename makefile_nt.edf to makefile and open user_nt.udf and read the instructions and do accordingly. 7) close FLUENT . Open command prompt ( start > accessories > command prompt ) type the following C:\ CD program Files \ microsoft visual studio .net\vc7\bin 8) type :- vcvars32 9)go to the libudf\ntx86\3d which u have created 10) type nmake 11) This will compile ur code and build a lib if u dont have any errors , if errors are present it will say so u need to debug it then. 12) once this is done u can open fluent again and load the lib u have just created , in this case it would be libudf.

I don't know it. I don't use Visual Studio anymore because I'm now on a linux platform.

However the path to the compiler is set during Visual Studio setup, if you accept to set system variables.
