UDF library not loading on Linux supercomputers

tom634 · August 1, 2014, 06:26

Hello all,

I wrote UDF and it works on Windows 8 and Fluent runned by SDK command prompt.

Then I saved UDF as UNIX file format in order to launch this on supercomputers with Linux. UDF has no any comments starting with "//", but "/* ... */" only.
I receive such error while compiling:

Primitive Error at Node 0: The UDF library you are trying to load (libudf) is not compiled for parallel use on the current platform (lnamd64).

No such file or directory
/home/***/users/***/libudf/lnamd64/3d_node/libudf.so

Any help would be appreciated.

I see a contradiction in your post (emphasis mine):

You don't show the error that shows up during compiling, but during loading. Apparently something went wrong during compilation, so you need to look at the error message given during compilation.

Problem solved, I had variable y1 in my UDF, I changed it to yy1 and it started to work. Do you know maybe, why with variable y1 it couldn't compile and load?

No, I don't know that. y1 is not a reserved name, so it should work as well as yy1. The error messages that are shown during compilation could give a hint what went wrong, if you are still interested to find out.
