这么大晶胞体系(而且又没对称性)根本不需要phonopy,获得声子带结构什么的也没意义。直接CP2K做振动分析,Multiwfn绘制振动光谱图就完了。DFT在一般条件下算不动,用GFN1-xTB还可能能搞搞 前面的人提到的网站,估计也肯定搞不动,网站里说了: For systems containing fewer than 20 atoms, the calculation typically completes within approximately two minutes when the server is idle. During periods of high server load, tasks will be queued and the completion time may be longer; once finished, the results will be available for download. For systems with more than 40 atoms, please contact us by email to arrange a separate calculation due to computational resource limitations. |

| 感到震惊,一千多个原子的体系计算声子色散,http://phononbench.cn/或许这个网站可以有所帮助吧。 |
