    Hi,

    Shell elements are appropriate for stress analysis. Normally based on the  dominant dimensions of the geometry the type of element is selected.

    Shell elements are used  when two of the dimensions are very large in comparison to the third one. Typically for all sheet metal parts, plastic components like instrument panels, etc shell mesh is used.

    Hi Ank,

     

    Note that the Dofs on shell and solid elements are not same. So if you are connecting shells and solids better you do it with either rigids or use tie contacts.
