Hello Nick Thank you, very much, for your insightful comments. Indeed, we have started with a 0 V calculation in all our tests, and the reported issue appears for V= 0 V. It also manifested when, after performing a successful 0 V calculation on the same heterostructure prior being relaxed in

Please use 4.1.5, it has checks for these kinds of things. Probably what you are seeing is that the charge is leaking out of the device region during your SCF. This is an indication of one or a combination of the following: - your initial Hamiltonian is far from the open-boundary one. I.e. your
