Centrifugal Pump analyses Help
 
Hello all,

For my design project I need to make cfd analyses for a centrifugal water pump.

I'm using Ansys 13 and Siemens Nx 7.5

I go over an Ansys 12 tutorial and I stuck due to a mismatch between two versions.
Problem 1 is I don't know which wall should I choose as interface side

Second problem is I don't know how to write an expression on post possessing part

I have only limited time and I'm open to all advice that you share..
Thanks in advance

do u use MRF or Sliding mesh?

in MRF you dont have to make interface surfaces. choose interior as BC.
