WebJan 15, 2024 · The Gaussian smearing method and a width of 0.05 eV was used for partial occupancies of the Kohn − Sham orbitals. The change of electronic energy was less than 10 −5 eV, which indicates a self-consistent energy. Moreover, the change of electronic energy was smaller than 5×10 −2 eV Å −1, suggesting convergence of geometric optimization. WebFeb 15, 2024 · Using the Gaussian smearing method and a width of 0.05 eV allows part of the Kohn-Sham track to be occupied. The energy of the electronic was allowed self-consistent when the energy change was less than 10 −6 eV. When the change of the energy was less than 0.05 eV Å −1, the convergence of geometric optimization can be considered. novel aircraft
