| Yuan: can you add a fake Hex over the hanging shell here? Give them zero stiffness and constrain the hanging nodes that the fake elements create.
I don't think it is a good idea although it would work theoretically. It would be a disaster when you try to do calculations over several tens of millions of elements this way. Maybe I should give up automatic interpolation but call DMPlexDistribute directly after setting up Dofs upon each node. Is it possible?
