hello everybody

i am graduate student and right now i am simulating the 3D model of centrifugal compressor. but i have many problems. in my case i used the single rotating frame using sliding mesh periodic. and include vaned diffuser. i had tried to follow the tutorial but still problems. and the tutorial was suggest to using the udf to located in the inlet boundary condition. such as tangential velocity, radial velocity and axial velocity. and i didn't know about it. if anybody know about it please help me and give me more information about it !
thanks you very much for your kind attention
