The mixing weight is more flexible, a too low value will make it converge slower but is more likely to converge in the end. A higher value can make it converge faster but will be more likely to ...

WebThe SCF convergence algorithm falls back to the default values during the optimization steps. Converging the CPHF in frequency/IR calculation Rarely, the calculation of the Hessian (frequency) will not converge and produces the "Out of Iterations- IterZ". This is usually due to precision problems so the CONVERGE keyword may help. WebAug 22, 2024 · 注意发帖时候看清楚板块,量化问题不要发到“计算机使用与Linux交流”板块,给你移动了. 提示已经很清楚了,ORCA的SCF没收敛。. 手册里专门有一节讲怎么解决 …
