  Hello,
  I apologize that my post will be quite large so I will try to explain step by step what I am trying to achieve and where I am stuck. (I have started using Ansys only recently, please forgive my mistakes or any misunderstandings on my side)
  I am trying to do a transient simulation in Fluent using the 6DOF Dynamic Mesh with Layering and Remeshing to study the flow through the turbine side of an automotive turbocharger.
  Geometry
  The cad design is made out of 2 components, a stationary volume and a rotating volume in which I performed the boolean subtract of the turbine impeller. It is worth noting that the clearance between the rotating region and the stationary domain wall is very tiny.

  EDIT:
  I forgot to add in the results from the simulation.
  Thank you!

  If the flow isn't crossing the contact region (interface in Fluent) it usually means something went wrong in the interface definition. As staff are not permitted to open attachments please repost the images. Whilst we can get quite tetchy with many posts for no good reason, or to bump a thread, several to get images in or to add detailed questions/comments are fine.
