[交流] 【求助】高精度优化后，计算能带时提示有问题

这是我的INCAR
SYSTEM = doped
Startparameter for this run
PREC =  high # medium, high low
ISTART = 0 # job : 0-new 1-cont 2-samecut
ICHARG = 11 # charge: 1-file 2-atom 10-const
EDIFF = 0.1E-04 # stopping-criterion for ELM
NSW = 0 # number of steps for IOM
IBRION = 2 # ionic relax: 0-MD 1-quasi-New 2-CG
ISIF = 3 # stress and relaxation
LREAL = Auto
优化时ICHARG = 2，改为11 计算能带时提示

就停止计算了
问题的出现好像是由于能带计算时把ENMAX增大，然后导致与前面优化是的ENMAX不一样就会提示的，那我是不是应该在优化时选用大一点的ENMAX就可以了？那ENMAX要多大呢？
