WebGive the calculation more SCF iterations ( "SCF(MaxCyc=N)" where N is the number of iterations in Gaussian ). This seldom helps but the next option often uses so many iterations that it's worth a try. Use a forced convergence method. (In Gaussian "SCF=QC" is usually the best but on rare occasions "SCF=DM" will be faster). WebGaussian默认的最大循环步数为64 (SCF=DM或SCF=QC方法则为512)，如果循环次数超过这个数目则会汇报convergence failure。在一定的情况下，不收敛的原因仅仅是因为最大 … cmr mount road https://vapenotik.com

WebMay 31, 2013 · Something that I have discovered is that when Gaussian (or other good ab initio software) fails to converge, there is something sketchy about what one is trying to calculate. Sometimes DFT calculations just aren't appropriate, especially in cases that require multiconfigurational SCF for even a zero-th order description. http://sobereva.com/61 http://sobereva.com/540 cafes near shaftesbury theatre
