How can I read superficial stresses on 3D castings? How are ´Membrane´ elements declared in Optistruct?

Hello,

 

In Ansys and Abaqus solvers I Used to apply a 'Skin' (2D elements based on the outer surface of 3D elements) on castings in order to read superficial stresses in Hyperview. These elements were membrane elements and were declared different than regular shell elements.
 

For Optistruct which type of element is the one suited as membrane element?

Is there any other approach to read superficial stress on castings?

 

Here is an image of the availabre trias type of elements, which one should I Use?
