Properly model contact between shell and solid

    • dddave


      I am modeling a pressure vessel with shell181 elements. The boss is made of solid186 elements. On the shell elements I generate the target170 elements and on the metallic boss conta174 elements are generated.

      To simplify the model I removed the internal pressure. So there should be no tension inside the structure at all.

      You should use bonded or MPC contact between shell and solid. The contact elements should be on shell elements while traget elements should be on solid elements.n
