    Tube inside a Tube shell element analysis- Solver fails, Bad Contacts?

      I’m doing a simple analysis with gravity of two tubes bonded together and the outside tube is fixed. The tubes are different materials and are all defined by their selected faces in the shell manger. If I remove the smaller tube (sleeve) from the assembly the analysis works fine. If I put the tubes together in an assembly as shown above the analysis fails.

      I have four bonded contact sets between the inside faces of the sleeve and the longer tube. Equal split lines between components and the diameters are exact.

      The assembly meshes fine, but I do get an error that contact entity cannot be processed properly with all four contacts. What am I doing wrong?
