Re: UDF COMPILATION
 
This error message is a result of not having the Microsoft Visual Studio C + + environment variables set up OR you do not have a Microsoft compiler installed.

Re: UDF COMPILATION
 
I got by 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 "2d".( MY simulation is 2d) 3) copy the udf (.C file) and the required header( u can get the header files from c:\FLUENT.INC\fluent6.*.*\ntx86\src) files into the "src" folder. 4) go to c:\FLUENT.INC\fluent6.*.*\ntx86\2d copy the contents into the 2d folder which you created. 5) go to c:\FLUENT.INC\fluent6.*.*\ntx86\src copy makefile_nt.udf and user_nt.udf to your 2d folder 6) rename makefile_nt.udf 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 \vc98\bin 8) type :- vcvars32 9)go to the libudf\ntx86\2d 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. -T.HARIHARANATH
