我刚接触MS计算，用castep中进行几何优化和能带计算时，出现错误，最后给出： Warning: electronic minimisation did not converge when finding ground state. 不知道要调试哪个参数，请高手指导，谢谢。 如能根据文件信息给出相应的指导解释信息，则不甚感激。 具体文档为 Pseudo atomic calculation performed for B 2s2 2p1 Converged in 16 iterations to a total energy of -70.4905 eV Pseudo atomic calculation performed for O 2s2 2p4 Converged in 25 iterations to a total energy of -429.5309 eV Pseudo atomic calculation performed for Y 4d1 5s2 Converged in 17 iterations to a total energy of -188.5056 eV Calculation parallelised over 1 nodes.
