Compile udf and load libudf library

starlight · February 17, 2015, 12:11

Hello everyone,
this is the first time I write/ask something here and I hope my question won't seem too boring and/or "stupid"!

I am a student and I have to solve a flux in a conduct with a Poiseuille velocity inlet profile: I can do that through an udf and when I try to compile it and then load the library Fluent 6.3 tells me this:

'nmake' is not recognized as an internal or external command,
operable program or batch file.

Warning: An error or interrupt occurred while reading the journal file.
Some commands may not have been completed.

Error: open_udf_library: The system cannot find the file specified.

I've found people who ask for help for my same problem and I tried all day long to do the things that someone said to them to fix this but I did not have success at all!!!

Could someone help me, please?
(I have a 32 bit notebook and I work with Fluent only, not with the whole ANSYS package).

Hi,

I had the same problem. I think it's because you don't have any C compiler on your computer.

Use the function interpreted, it should work and for simple UDF it's as fast an function compiled.

Good luck

Thank you for the answer! Unfortunately I have already tried the function interpreted but the problem still exists!

It's strange.

Is the error the same with the interpreted function ?

Yes! It's the same error!

Check your installation path of Fluent to see if you have "cpp.exe" file. It should be located in "C:\Program Files\fluent\ntbin\..." or something like that.
