The problem with this structure is essentially the same, i.e. some atoms are too close which causes huge forces in the system. Reducing POTIM should work but it will also slow down the convergence.

WebBRIONS problem: POTIM should be increased. POTIM is a coefficient of particle movement in optimization, which is the distance that determines the next step of movement. As long as it converges, POTIM does not affect the final result, but affects the convergence speed of …

Web11 Apr 2024 · You should check that the SCF settings are OK (proper energy functional, very small smearing, enabling extra grid for force calculations etc.) and the tolerance on the SCF energy and forces are stringent enough to obtain converged values. Still, the doubt remains if you have bulk 3D structure but you have a sampling of 221, either on the k ...

Web7 Apr 2024 · SIGMA = 0.05 is quite a large smearing; you should check that for SIGMA -> 0, the forces converge. Also, EDIFFG = -0.01 is not tight at all, a good value would be 10^-4; however, depending on the system, you might have a corrugated PES and you can get the convergence with 10^-4 only by carefully adjusting the POTIM parameter and gradually … chicago catholic league football 2022WebDear Prof. A.
