Hello!

I do have a question concerning interactions of shell-elements. See the attached pictures to get an idea of what i mean.

I have 3 parallel shell-faces: Top-, Mid- and Bottom shell, with a distance of a few mm between each other. Each shell-face does have a certain thickness so that they would "touch" each other.

Is it possible to establish the following interaction: TOP-to MID-shell and MID-to-BOTTOM-shell without overconstraining the model? If yes, how should one do that?

I'm using abaqus 6.13-4.

Thanks a lot and best wishes!

Marc
