Hi,

I'm trying to follow the dynamic mesh tutorial in Fluent 13 and Fluent 6.3.26 on windows7 64 bit. When I tried to compile the UDF and build it an error occurred:
" 'nmake' is not recognized as an internal or external command,
operable program or batch file
.
So I found the nmake.exe file and copy it to the Fluent\ntbin\win64 then this error vanished and the report is
Deleted old libudf\win64\2d\libudf.dll
1 file(s) copied.
(system "copy "C:\PROGRA~1\ANSYSI~1\v130\fluent"\fluent13.0.0\sr c\makefile_nt.udf "libudf\win64\2d\makefile" ")
1 file(s) copied.
(chdir "libudf")()
(chdir "win64\2d")()
# Generating ud_io1.h

Done.

Which I think is ok.

But when I try to load the library "libudf" an error appears

Opening library "c:\......\dynamic_mesh\dynamic_mesh\libudf".. .
Error: The UDF library you are trying to load (libudf) is not compiled for 2d on the curent platform (win64).

The system cannot find the file specified.
c:\.........\dynamic_mesh\dynamic_mesh\libudf\win6 4\2d\libudf.dll
Error Object: #f


I've tried to install MS visual studio 2010 professional and MS visual studio 2008 with all the prerequisites but no way.


Any help is appreciated, Thanks

I have a very similar problem,

The UDF library you are trying to load (libudf) is not compiled for 3d on the curent platform (win64). \libudf\win64\3d\libudf.dll

here you can find help: http://www.cfd-online.com/Wiki/Fluent_FAQ

I have reinstalled the compiler as they say now i will try to download the sdk package to see if that helps me out.

Thank you for your reply

Finally, I found a solution. It works fine when I run the fluent from the command prompt of the visual studio, But an easy way is to set the environment for the UDF in the fluent as section 5.1.2 in the user guide. Finally it works.

Thanks

I followed your suggestion, and although it can now compile, it is not stable (when I re-load my file with compiled library fluent just crash-exits). Did you make it work stable with FLuent 6.3.26 on Win7-64bit? My suggestion is that compilation for v6.3.26 is not compatible with Win7-64bit, at least not fully compatible, but I need more people response. Thanks

Opening library "/work/massi/libudf"...

Error: the UDF library you are trying to load (libudf) is not compiled for parallel use in current platform (Inamd64).

Access violation error indicates the fault inside a UDF. It is trying to access a quantity which is not there, as far as I know

To overcome the problems related to any compiling errors, follow the ensuing steps:
1) install Microsoft visual studio 2010 express.
2) install Microsoft windows sdk v7.0
3) run setenv.exe file from ur system location C:\Program Files\ANSYS Inc\v145\fluent\ntbin\win64\setenv.exe.--(to set required environment variables)
4) Restart ur system and launch fluent using CMD shell [(start menu<<All programs<< Microsoft windows SDK v7<< CMD shell). Note :in CMD shell ,type fluent].
IMPORTANT: pay heed to the working directory while launching fluent as it should contain the source file that needs to be compiled.
