Orca this wavefunction is not fully converged

http://bbs.keinsci.com/thread-21209-1-1.html 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.

WebAug 29, 2016 · 1. Generally, you need all the 4 parameters to converge. However, displacement values may be large unrelated to the question wheater your geometry is stationary or not. It is a judgement call and you should have your chemical insight into the system to see wheater these values raise a red flag or not. – Greg. 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 ... gentle submissive crossword https://asadosdonabel.com

WebThe self-consistent field (SCF) method is the standard algorithm for finding electronic structure configurations within Hartree-Fock and density functional theory. SCF is an iterative procedure and can, depending on the situation at hand, sometimes be difficult to converge.
