WebFeb 7, 2024 · It only took 3 iterations, which sounds implausibly small - unless you already have a guess that is extremely close to convergence. The log file also says that some of the states aren't converged, and errors of 0.3 seem pretty damn high to me. Maybe there's a problem with a too high convergence threshold, or the density isn't updating at all?

ORCA Input Library - SCF Convergence Issues

WebMar 7, 2015 · 16. There can be many reasons for the SCF to not converge. The initial guess wasn't great, and the convergence is slow. Increasing the number of SCF iterations can help here. The SCF oscillates. This can happen if there are two orbitals close in energy. Using damping, mixing (i.e., the next iteration is 50% the old and 50% the updated iteration ...

Since saddle points are also extrema of the energy functional, the orbital gradient vanishes and the SCF equation F C = S C E is satisfied [1].

WebJun 15, 2016 · There is no physical requirement for a wave function to be smooth, or even continuous. At least if we accept the common interpretation that a wavefunction is nothing else than a "probability amplitude". I.e. it represents, when multiplied with its complex conjugate, a probability density.
