How to mesh an enclosure around a model

  Dear all,
  The standard meshing in Ansys Fluent usually ends up with coarse and low quality mesh. Thus, I have been looking for an opimal method for meshing large-size enclosures around my model. The "Sweep" method is suitable for the cylinder at the center, however, my enclosure needs a proper meshing.
  
  I have tried hex dominant and regular tetrahedral methods but the mesh is still coarse. Is there any helpful techniques to obtain better mesh in such situations? Thank you

  For using hex meshing you will need to split the geometry.

    I guess this mesh looks much better. I tried to split the geometry and apply hex dominant method as you suggested. Thank you very much
