WebDec 1, 2024 · 2- If the energy of the final scf differs significantly, then it was converged to other state. In this case, the cure is to start a separate scf with new cell parameters and atomic positions. Moreover, I feel that using a relatively large mixing_beta may cause oscillation between metastable states and lead to no scf convergence.
