How to create a fluid volume inside a fluid volume

  Hello
  I have one fluid region which encloses the Turbofan, however, i have put an extra fluid region closer around the turbofan with a lot more mesh.
  
  The problem i face is that i am not sure what the boundary condition should be for the fluid region inside the other fluid region. (both fluids are air and the one inside the other fluid has more elements - more mesh). Any help would be appreciated.

  For conformal mesh you will need to subtract that smaller fluid volume from bigger one in SpaceCLaim. THen you will need to use share topology. You can also consider using BOI option in meshing. nPlease check following videosnnAnsys Meshing Sizing:nhttps://www.youtube.com/watch?v=w4q6q8nKF3UnnDM Share topology:nhttps://www.youtube.com/watch?v=IO4ZtwZdD2InnSpaceClaim Share topology:nhttps://www.youtube.com/watch?v=h43E1YO1LiMnRegards,nKeyurnHow to access Ansys Online Help DocumentnHow to show full resolution imagenGuidelines on the Student CommunitynHow to use Google to search within Ansys Student Communityn
