how to generate an annulus with inner pipe rotate?
 

Hello, Gurus,

I am a new user of GAMBIT and FLUENT, i am working a small project on annular flow, now i have a problem, i generated a 3D annulus (half part)and meshed, and then run with FLUENT, but sinceit is a 3D problem, I have no idea how to examine the annular velocity distribution, and also, i am not sure of my procedure, and mesh method, is there anyone has an example or tutorial,or existiong one that i can have a look? thank you very much!!

also, if the inner pipe is rotating, then what shall i do different from the previous one?
