Hello All, I hope this is a simp

Hello All, I hope this is a simp

(OP)
Hello All,

I hope this is a simple question that may help others as well. Until recently, my models (Abaqus/Explicit) have involved parts fastened together in the assembly but I now need to set one thing on top of another (for example, an object on a table), letting gravity hold them together and I wonder if there's a best-practice recommendation or general rules for positioning and contact.

The specific problem is a 2D shell with some thickness resting on a flat analytical rigid surface. When positioning the parts in the assembly, do I bring the bottom nodes of the object to exist in the same plane as the rigid surface or do I account for the shell thickness as well (assume the shell thickness extends out beyond the nodes, like a 'middle' shell section definition)? Are there any peculiarities in the contact definition for this kind of interface or should 'general' work? Thanks.
