your udf was NOT compiled.You know that from that error regarding "nmake"
As a result, when you try to load the udf, there is nothing to load (since it wasnt compiled in first place)

Try to compile properly, look at some tutorials explaining how to link the c++ compilers in fluent

You are compiling "with C++"?
i take it you tried to compile externally? from what i remember the compilation needs to be done from fluent. it'll automatically copy the udf library in your directory while doing so (i.e udf.h)

hi everybody,

Does anybody know what's the problem with the following error while compiling a UDF?(i have already installed both visual studio 2006 and 2010)

The UDF library you are trying to load (libudf) is not compiled for parallel use on the current platform (win64).
The operation completed successfully.

E:\Program Files\ANSYS Inc\v140\fluent
tbin\win64\libudf\win64\2ddp_host\libudf.dll



thanks previously

Are you trying to load the library, or trying to compile the library?
The warning that you copy here, says you are trying to load it in a parallel environment, while it was not compiled for that.

The UDF library you are trying to load (libudf) is not compiled for parallel use on the current platform (win64).

Dear Pakk,

so sorry, i'm almost a beginner in using Fluent so i didn't understand what u meant. from define tab in fluent v.14, i clicked on user-defined then functions then complied after that in source files i selected my udf then i clicked on build and then clicked load and that error came up!!! i don't know what's the problem. is it from windows?is it from the udf itself? have i done the procedure correctly?!!!!!
thank u so much

Hi vga67,

I think you are running a parallel version of Fluent, are you? (At the start-up screen of Fluent, did you select 'parallel' or 'serial'?)

In that case, what this error message means is that you try to load a serial version of the udf into a parallel version of Fluent.

What you should have done, is load a parallel version of the udf.

You make a parallel version of the udf by compiling the udf in a parallel version of Fluent.

From what I read, this is what you tried to do. But, something must have gone wrong when you tried to compile it. Is there an error message before the one you showed earlier?

The UDF library you are trying to load (libudf) is not compiled for 2ddp on the curent platform (win64).
The system cannot find the file specified.

c:\users\vhid\desktop\fluent-mdm-tut-01\udf\libudf\win64\2ddp\libudf.dll

What is shown on your screen after you click 'build', and before you click 'load'?

The line "'nmake' is not recognized as an internal or external command,
operable program or batch file.
" is an error message.
Your compiler is not properly set-up, so compilation failed.

I am no expert in setting up compilers, but have been some threads about this on this forum. Search for SDK, that might help.

If you are on Windows: are you running Fluent from Visual Studio?

You have to initialize Fluent from VS command prompt, otherwise I don't think Fluent will recognize VS as the compiler.

To do that, you must have Visual Studio installed. You can download it for free from Microsoft.
