I saw @rszoeke already made a post about it but maybe some of you guys can go into detail.

Fictitious Clearance

Hi @BenLewis, basically when adding a Fictitious Clearance to a contact surface, we add a layer of a fictitious material (with no additional stiffness) with the defined clearance as thickness. On an algorithmic point of view, when it comes down to compute the (signed) contact distance, the solver removes from the actual geometrical distance the fictitious clearance and the result will be used to evaluate the contact state (open/closed) and the contact forces. So, if your geometry originally h…
