I am running Fluent 6.1.22 on a 64 bit workstation that's running fedora core with opteron processors. We are using the 32 bit fluent, as 64 bit won't be available for fedora untill version 6.2.

I have a udf that runs perfect on linux redhat. I compiled the udf on the new workstation (compiled fine), but when I try to "load" the udf, I get the message:

Opening library "libudf"... Error: open_udf_library: No such file or directory

I checked the directory structure and file content of the libudf directory. It is exactly the same as on the Redhat machine. Anyone know what this error is and / or how I can work around it? Interpreting the udf can't be done.

Thanks

Karl

Usually this message means that FLUENT is not able to find the libudf.so compiled file.

This file is located in:

2D single precision solver -> libudf/lnx86/2d/libudf.so

2D double precision solver -> libudf/lnx86/2ddp/libudf.so

3D single precision solver -> libudf/lnx86/3d/libudf.so

3D double precision solver -> libudf/lnx86/3ddp/libudf.so

Pay attention to put the source file of your UDF in the same directory where you saved the .cas file.
