Orca energy check signals convergence
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 http://wiki.tangzeyuan.com/code/orca.html

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 ).
WebJan 5, 2024 · The default SCF procedure uses a combination of EDIIS [ Kudin02] and CDIIS, with no damping or Fermi broadening. In Gaussian 16, SCF=Tight is the default. The SCF=QC option is often helpful with difficult conversion cases. For difficult-to-converge ROHF wavefunctions, where QC cannot be used, add Use=L506 to the route section. hidden spy usb cameraWebMay 22, 2024 · The set of signals that cause the system's output to converge lie in the region of convergence (ROC). This module will discuss how to find this region of convergence for any continuous-time, LTI system.
