    Modeling an air duct with shell elements, applying pressure.

    When you use a shell element it is wise to choose the elements to represent the mid-surface. Doing that, you guarantee that the results related to "mid" will correctly represent the displacements and stresses on that surface. For instance, when you model a tube (or duct) by its midsize surface...
