Okay, so I've boiled it down to a minimal example, and I am very confident I ran into a bizarre and specific glitch.

  1. Create a cylinder starting at (0,0,0), and put the other end at (-600mm,0,0) with a 60mm diameter (-600mm,30mm,0).
  2. Create a sphere with origin at (-330, 0, 0) and put its end point at (600,0,0)
  3. Combine the cylinder with the sphere and delete the cylinder and boolean cylinder to leave the sphere with the void cylinder.
  4. Create a named selection for the sphere surface and the internal cylinder surface. 
  5. Import into fluent and mesh with default settings
  6. It will fail to mesh the sphere surface and lose the named selection. 

Now, the fun part. If you change the endpoint of the sphere to 601 or 599, it works fine. It seems like an oddly specific glitch to run into me.Â
