,I heavily appreciate your guidance on these topics. Because it is usually not possible for students or fresh engineers to talk in detail about these kind of topics either in schools or at work. nSince we have brought up the topic for a shell element, i want to ask a side question as well. For a shell element, along the thickness there is only one element. Then why do we see a difference in stress or displacement results along the thickness of shell elements in ANSYS?nAnd also why do shell elements take less time to solve than the solid elements even though the nodes on shell elements have 6 DOFs while for a solid element has 3 DOFs only?n
