hi, I am using compiler visual studio c++ 2005 and I am getting this error when I build udf. I have tried other options such as creating a folder name "libudf" (library udf) in that i kept case files, and run the file and then defined user defined functions.

would u suggest how to give path for nmake file to be recognized by the fluent.

Error:

Deleted old libudf\ntx86\2ddp\libudf.dll

1 file(s) copied.

1 file(s) copied. (system "copy C:\Fluent.Inc\fluent6.2.16\src\makefile_nt.udf libudf\ntx86\2ddp\makefile") 1 file(s) copied. 0 (chdir "libudf")() (chdir "ntx86\2ddp")() 'nmake' is not recognized as an internal or external command, operable program or batch file. 'nmake' is not recognized as an internal or external command, operable program or batch file.

Thanks a lot for quick response
