Flow between rotating disks
 

Dear Abdul Aziz Jafaar
I am trying to model flow in FLUENT between two rotating disks which are rotating in opposite directions. Seems that you have some experience with this sort of modeling. May I ask you for some suggestions?

1- Which function of FLUENT is the best approach for this problem,
Dynamic mesh, user-defined functions, or multiple moving reference
frames?
2-What type of mesh will be the best, structured, unstructured, or block structured?

Thanks for your time.
