  When I tried it didn't show any worrying penetration, though there were some strange graphical glitches with transparent elements in the solution. How far was the penetration and on which parts?

  
  

  Be aware that the default deformed view scaling factor might be greater than 1 for small deflections so it can look like it's penetrating when it's not really.

  Thanks Victor for the explanation. It is the scaling factor is way too big (18.0, Automatic) so it looks like penetrating. When it is set as 1.0, it is not.

  
  

  For the strange graphical glitches, when I unrefine the bottom roller without changing other factors, the glitches are gone. Any insight on this? Is it caused by too fine elements or calculation error of the solver?

  I'll have to investigate because it certainly seems like a bug. No idea what's causing it yet.

  I just noticed the mesh isn't properly connected in some places. Use View->Open cracks to reveal the gaps and Mesh tools -> Merge nearby nodes to correct it.
