WebFeb 15, 2024 · The force cutoff (EDIFFG =-0.01) is not converging rather fluctuating in the same region ( in the range of -0.9 to -0.3E-02). I set the maximum number of ionic steps (NEW=200) and it reached and I repeated with the CONTCAR again (already repeated 4 times). Please guide me on why the force cutoff is not converging.
