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?

Thank you for the idea Rahul. Had not tough about it.
Thank you for you time.

You can model the shell as membrane, by setting the MID2/3=0.0 (basically we are reducing the bending stiffness to zero, it will act like a membrane). which we can do by editing the PSHELL property card.
Hello Rahul,
By setting MID2/3 = 0 you mean making them have the BLANK option?
I cannot modify the value of MID2 and MID3 numerically to be 0. I attached an image.
