Are you using fluent on windows?

Did you make that libudf on serial fluent? Easiest way to fix this is simple to make a new libudf with parallel fluent and then use that new libudf.

Basically open the problem in parallel mode, compile and load the library and done. You must compile the library in the very same computer that you will run the problem, because, the compilation is specific for the computer arquitecture (cores, SO, etc). If you compile the library in one pc and then run the case in another one you have this kind of problem.

sir please guide me how to compile libudf.

The UDF library you are trying to load (libudf) is not compiled for parallel use on the current platform (win64).

above error is always showing..

This error usually appears when you use x32 compiler on x64 system. You have to make sure that you use correct compiler. Sometimes it's very tricky to set 64x compiler for ansys, search this forum and you'll find some solutions
