  Hello,
  Why is a transition with at least two elements required across the wall thickness? What does this have to do with shell and solid models?

  Hello Mehmet,
  It is a general guideline to use at least three elements through the thickness of solids. It is to correctly depict the stress through the thickness of a thin body under a bending load, which results in a substantial gradient through the thickness. When using shells, you only need one element on the surface of a body with an allotted thickness because shell elements have internal equations that appropriately compute the stress across the thickness when the element is carrying a bending force.
  To get a better understanding of analyzing thin structures efficiently, have a look at this Ansys Innovation Course:
