I'm trying to mesh two bodies in bonded contact without using shared topology (which, to my knowledge, welds them together). My professor would like the meshes to match but I haven't been able to get the contact mesh feature to work. It gives me the following error: "The faces cannot be the interface between two bodies in a generalized body." I have two questions:
1. Is there an appreciable difference between shared topology and bonded contact? If I can just use shared topology, that would make things much simpler, but my prof said he wanted them bonded, and I'm not sure I know the difference.
2. Is there a better way to mesh match than using the contact mesh feature? I tried to use the same seeds since the body edges line up exactly but I got the error above.
I'm simulating a pressure vessel with a notch defect wrapped with a composite repair. I've divided the pressure vessel and the repair such that the outer surface of the pressure vessel and the inner surface of the repair have the exact same surface area, so I thought that would make the meshes match up by default.
