网上没找到解决方案,请问这是怎么回事,要怎么解决?请各位老师指教
报错:

计算的体系是异质结,POSCAR文件:

想做一下结构优化,INCAR文件:
Global Parameters
ISTART = 1
ISPIN = 1
ENCUT = 500
PREC = Accurate
NCORE = 4
LWAVE = .TRUE.
LCHARG = .TRUE.
ADDGRID= .TRUE.
Lattice Relaxation
NSW = 300
POTIM = 0.5
IBRION = 2
ISIF = 2
EDIFFG = 0.005
Electron Scf
EDIFF = 1E-6
ISMEAR = 1
SIGMA = 0.2
复制代码
POTCAR用此命令生成
cat POTCAR-W-sv POTCA-Se POTCA-Cr-sv > POTCAR
复制代码
我用vaspkit的101-LR生成INCAR,不知道为什么不会自动生成POTCAR(有配置赝势库的路径),所以只好手动制作POTCAR

得102 生成KPOINTS 才能生成对应POTCAR吧。你可以grep POTCAR看看

刚才没注意看,可能自己弄的赝势有问题,我用103重新弄了个赝势,现在似乎可以计算了。。。希望别再出错
