|                                                                            |
|    You have a (more or less) 'large supercell' and for larger cells    |
|    it might be more efficient to use real space projection operators    |
|    So try LREAL= Auto  in the INCAR file.                            |
|    Mind: If you want to do a very accurate calculations keep the       |
|    reciprocal projection scheme       (i.e. LREAL=.FALSE.)          |
|                                                                            |

上面是运行过程中的

INCAR里这样写的
ISTART = 0
ICHARG = 2
ENCUT = 450
NFREE=2
ISIF=4
IBRION=1
NFREE = 2
EDIFF=-0.02
PREC = Accurate

谢谢各位了
