I'd like to use unique_ids to identify elements and nodes without worrying about renumbering, but before I do that I'd like to understand a bit more about how unique_ids are defined.
In particular, what is the idea behind how we generate the unique_ids? From the code in replicated_mesh.C, for example, it looks like the unique_ids are set in add_node and add_elem, with _next_unique_id being incremented each time a new ID is set. This looks simple enough, but I was wondering if there's anything else to it? One concrete question I have is if I create two Mesh objects by reading in the same mesh exodus file twice, will those two meshes have matching unique_ids? I guess they will simply because "add_node" and "add_elem" will be called in the same order during those two read operations. Thanks!
