  Hi iam working on the Rotating mesh of propeller in an MAV body and after setting up all the boundary conditions iam getting exactly the same cd values but not the Cl values can any one tell me.
  Iam getting and info during fluent that my" two interface zones are penetrating which would adversely affect your results"

  Hello Are you using the MRF approach? What is your computational mesh like? Could you please share a screenshot of your mesh?
  I'm sure you have already verified this - make sure that you are using the correct reference values to estimate Cd and Cl.

  hello i am working on centrifugal pump using MRF approach, I am trying to simulate rotating impeller. I am using un-structured meshing. while setting impeller-volute interface and running the calculation, iam getting reversed flow at inlet.
  "Info: Interface zones, 995 and 4, possibly penetrate each other.
  This could adversely affect your solution."

  Have a look at the interface faces, how do they look?
