Superficial Stresses on 3D Castings? Membrane elements?

Recommended Posts

I asked this question before in the forum but I am open to hearing new suggestions.

 

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. (.01 thicknesss 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?

 

Thank you!
