Sandwich shell

how do you model a sandwich shell with several layers? do you have an example please to share with me?
my element is made of 10 layers of glass and carbon fibres with a pvc core on the middle

Hello @Lydia ,

in Karamba3D V 2.2.0 there is currently no straight forward way to simulate sandwich shell elements. One would have to work with two layers of shells which are connected via springs or beams.
A sandwich shell cross section is however on the todo-list.
