UDF in parallel version of fluent
 
Hi I have linux pc cluster. And, only parallel version of fluent was installed on that machine. The machine has not serial version, but only parallel version.

To test capability of udf, I copy one code from UDF Manual, then, compiled it. But, When Fluent loaded the UDF library, Fluent said that: "Primitive Error at Node 0: open_udf_library: No such file or directory"

What's the problem?

Check udf handbook chap.7.3.1: " 7.3.1 Common Errors Made While Loading Your Compiled Library

You will get an error message when you try to read a case file that was originally saved with a shared library that you have subsequently moved to a different location.

Opening library "libudf... Error: open_udf_library: couldn't open library: libudf/ln86/2d/libudf.so

You will get an error message when you try to load a shared library before it has been built.

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

Special Considerations for Parallel FLUENT

If you are running the parallel version of FLUENT on a Windows network, the directory containing the shared library (e.g., sharedlibudf) must be shared with all of the remote nodes in the cluster. If you forget to enable the sharing option for the library directory using the Windows Explorer (see Step 8 of the previous section), then FLUENT will hang when you try to load the library (e.g., sharedlibudf) in the Compiled UDFs panel.

As far as I know, for a parallel license one serial license is required. Please check it out with ur support.
