Orca this wavefunction is not fully converged
WebJan 26, 2024 · The first is for finite momentum, the second for finite energy. – Sean E. Lake. Jan 26, 2024 at 3:51. 3. The wave functions for bound states are required to vanish at infinity because, intuitively, if there is a non-zero probability of finding the particle at infinity, it is not bound. This does not hold for unbound (or scattering states ... WebJun 22, 2024 · In Gaussian, there is a stable keyword that checks the stability of the wavefunction. Using stable=opt reoptimizes the wavefunction until a stable one is found if there is an instability. My question is - when do you use this stability check?

Did you know?
WebUltimately, the convergence behaviour also improves with reduced electron numbers. If, for example, calculations for neutral radicals do not converge, a converged wavefunction can often be obtained for the corresponding cationic systems (lacking one electron). The cation wavefunction can then be used as the initial guess of the radical system. WebMar 11, 2024 · When ORCA comes to solve the CP-SCF equation, it performs the solution until a certain interaction but after that fails in convergence. I have changed the converge …

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 ...
