Orca energy check signals convergence
WebMar 7, 2015 · 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. WebApr 25, 2008 · You can check the convergence graphically (if gnuplot is installed) by calling cgnce If the energy starts to oscillate, the damping factor is too high... use another orbital shift ($scforbitalshift) make sure that $scforbitalshift is set to 'automatic 0.1' and not 'closed shell'. closed shell used to be the (very) old default, but

WebDec 10, 2013 · A three-dimensional propagation-model based passive acoustic tracking method was developed and used to track a group of five offshore killer whales (Orcinus orca) using their emitted clicks. In addition, killer whale pulsed calls and high-frequency modulated (HFM) signals were localized using other standard techniques. Based on these … WebMar 26, 2024 · It is possible that using tighter convergence criteria on the geometry optimization process would solve this issue. However, the Potential Energy Surface (PES) is indeed very flat, with the H atom roaming almost freely above the surface (see e.g., Figure 2 ).
