Hi all, I am running a FEM simulation codes (MOOSE) which is built on libmesh. I encounter the failure of "*neigh_has_remote_children*" assertion. The error occurs only with parallel runs. I searched a bit and learnt that the "find_neighbors" misinterpret the nodes on the common side. I don't understand the detailed mechanism completely. But I am wondering how can I avoid this kind of error? Is there a direction I can work on in my input or mesh? Here is the error message.
