Yes, that issue (using smearing in berry phase calculations) is known and honestly annoying - for magnetic insulators I have to do extra steps in order to compute polarization.15.11.2020, 23:34, "Paolo Giannozzi" :On Sat, Nov 14, 2020 at 9:13 PM Sergey Lisenkov wrote:Question:

No: QE complains and stops if you try a Berry phase calculation in a
crystal treated as a metal (with tetrahedra or
Dear community, Question: Does QE perform a check for the structure to be insulator before proceeding with Berry phase calculation? I'm studying a material under pressure, which is ferroelectric. At some pressure, the structure becomes metallic (from DOS), but polarization calculation does not
