Question about Tutorial 13 of CFX
 
Dear friends,
In fact in the tutorial 13 of CFX the flow between an annular is solved, which the inner circle rotating around its own axis, as a project I want to simulate that annular when the inner circle rotates around the axis of outer circle which is fixed, does anybody know how can I do that ? I think I should use mesh motion but I do not know if I should define the velocity of inner circle or location of inner circle ?

Please help me.

Sincerely

This is easily done using rotating frames of reference. Have a look at the tutorial examples 14, 26 and 33-35 for tips on using RFR.
