Hi,

I'm running through the Fluent tutorial on Dynamic Meshes. At Step 8, when adding the source file (valve.c) as a UDF, I get the following error mesages after building and loading:

******************************8

1 file(s) copied.

1 file(s) copied. (system "move user_nt.udf libudf\ntx86\2d")0 (system "copy C:\Fluent.Inc\fluent6.1\src\makefile_nt.udf libudf\ntx86\2d\makefile") 1 file(s) copied. 0 (chdir "libudf")() (chdir "ntx86\2d")() '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.

Done.

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

Error Object: ()

*************************** I'm running Fluent with Windows XP. In the source file window only "valve" appears, rather than the entire path (eg. c:fluentinc./tutfiles/dynmesh/valve.c).

Does anyone know how to resolve this problem?

Your help is much appreciated.

Thanks in advance

Alex

are u sure ur .c file is compiled properly?? it looks like there is confict with compiler. Some time ago i got same problem with Windows machine while using UDF. but then i moved to Linux system and it could compile it properly. Try on unix/linux mahine if you have access.

Hi, thanks for the response,

yes, I just tried to compile it on a Linux System and it is giving me the same error messages.

Has anyone tried doing tutorial number 11 in the Fluent 6.1 Manual?

If anyone knows how to solve the problem please let me know.

Thanks

Hi,

you need installed a compilor on your Pc, the error information tell you "nmake" doesn't work. the tutorial case is no problem in fact.
