Hi everyone,

My concern appears when I am loading a compiled udf with FLUENT 6.3 --- Opening library "libudf4fluent"... Error: open_udf_library: L'accès à cet emplacement de la mémoire n'est pas valide. (Means: invalid access to memory location) Error Object: () --- I guess that this error message comes from Windows. (OS: Win32 XP SP2) This is not a basic udf because the C source files calls Fortran subroutines defined in an object file. The libudf.lib and libudf.exp are created without error with the CL compiler of Visual C++ 2005 Express Ed (fortran compiler is g95).

Does anyone have an idea how to fix this problem?

With Best Regards

Cyril

Hi everyone,

The libudf.dll created after compilation was missing and lead to the error. I compiled again, ensure that libudf was created and load without any error.
