I have two objects,one is wrapping the other.So the two objects have coincident faces at the interface between them(Like 500 coincident faces ). When I do the assembly,and automatically search for contacts,none appear . therefore when i do a simulation,the wrapping object dives into the other object as if it wasn't there or they weren't touching. Please help me to find the contacts so i could run a simulation and the wrapping object stops at the second object bonded to it. thanks.
