【求助】MS中CASTEP的一个计算问题
|
|
我在用MS的CASTEP计算钠氟石（Ca2NaSiFO4）的拉曼普峰时，结构优化好后，双击calculation，选properties里的polarizablity,IR and Raman spectra.可是弹出一个这样的对话框：the following features are not supported: polarisability. 在最后出来的文件中找到这样的信息： cannot have fractional number of electrons and FIX-OCCUPANCY=Ture; cannot have fractional number of electrons and METALS-METHOD=NONE. 请问这应该怎么解决呢？望高手指点~ |
