相关文件放在下面了,只有一个其中一个自由度的其中一个位移报了这个问题,请问是否对最后的弹性常数结构会产生很大的影响?谢谢。
VASP日志的出错部分节选如下:
14 F= -.33392136E+03 E0= -.33392136E+03 d E =-.935691E-11
Finite differences progress:
Degree of freedom: 4/ 18
Displacement: 1/ 4
Total: 13/ 72
generate k-points for: 5 5 4
VERY BAD NEWS! internal error in subroutine IBZKPT:
Reciprocal lattice and k-lattice belong to different class of lattices. Often results are still useful... 96
K点是用KSPACING自动产生的,INCAR如下:
ENCUT= 550 eV
ISMEAR = 0
SIGMA = 0.05
PREC = Accurate
EDIFF = 0.00001
EDIFFG = -0.01
NELM = 100
POTIM = 0.015
LWAVE=.FALSE.
LCHARG=.FALSE.
IBRION = 6 (Determine the Hessian matrix)
NFREE = 4 (How many displacements are used for each direction, 2-4)
ISIF = 3 (Stress/relaxation: 3-Shape/Ions/V)
NSW = 1 (Max ionic steps)
KSPACING = 0.2
KGAMMA = .TRUE.
