Am I missing something really obvious in the meshing environment?

  Hi, I'm more used to abaqus, but am trying to mesh this shape:
  
  now, I have split the faces as I have, so that I can have hex elements on either side of the join in the middle (where it is just simple tube), and then tet elements in the middle where the geometry is more complex. I have tried using a multizone or hex dominant method, but it just fails to mesh. In Abaqus, it's possible to choose the mesh type for subregions of one component/part, but I can't find a way to do that on ANSYS. Is there any way to get this to mesh nicely?

  I could split the body and sweep, but that complicateds the model by requiring contacts. Is there a better way?

  Sebastian,
  Use SpaceClaim to split the body instead of just the faces. You will end up with 4 bodies. On the Workbench tab, use the Share button. That will create shared topology. In Mechanical, select the ends to mesh first and they should automatically get a hex mesh. Then mesh the center body and it will get pyramid and tet elements that share nodes at the split planes. No contacts will be created.

  That worked well, thanks! trying to like your comment but for some reason it doesn’t appear to work
