Solid model with shell skin
Solid model with shell skin
(OP)
Hi all,
Can someone explain to me why ones would build a finite element solid model with a shell skin? Is it for more accurate answers on the surface? How does one determine the shell thickness to get the most accurate answer bearing in mind not to add too much material or additional stiffness to the model?
Thank you.

You are right,
but tets and triangular shells are still not as good as hexahedrons and general shells respectively and I am still sceptical of using them wherever high strain gradients are involved.
Perhaps one can use hexahedrons in critical regions coupled to tets in rest of the model.In ANSYS one can do that.
