Thermal steady, Friction-less contact = No contact

  Hello!
  
  So, with ANSYS I can set the type of contact and the thermal conductance. I noticed that in all types, with the exception of the friction-less contact I can set even at a physical distance with the bodies, for friction-less contact I have to set with the off-set distance. However my simulations started doing an error, where I can't seem to connect (thermally) two bodies for the friction-less contact, even if I touch the two bodies and set "adjust to touch".
  
  I have tried everything, and I'm out of ideas. What could I've been missing?

  It's not clear what you have and what you want to do and what the error is. Please be specific and insert images of the geometry.

  The problem is that the program doesn't seem to capture all the nodes even if there is NO DISTANCE between the surfaces. Look at the contact tool info for the bonded and friction-less contact, all set to adjust to touch:
  
  Which give different flux results between the surfaces.
  
  The geometry is something like this:
  
  Were the center has different thermal conductance as the external region.
  
  Also it doesn't matter if I make the contact with the surface of the target body (block under the cylinder) with a project surface equal to the region of the contacts, the results are the same.
  
  Thanks
