[交流] 【求助成功】vasp 计算出错 已有2人参与

计算体系的时候出现
WARNING: PSMAXN for non-local potential too small
LDA part: xc-table for Ceperly-Alder, standard interpolation

VERY BAD NEWS! internal error in subroutine IBZKPT:

POSCAR, INCAR and KPOINTS ok, starting setup
FFT: planning ...           1
reading WAVECAR
entering main loop
       N       E                     dE             d eps       ncg     rms          rms(c)

hit a member that was already found in another star
hit a member that was already found in another star
hit a member that was already found in another star
  hit a member that was already found in another star
hit a member that was already found in another star
hit a member that was already found in another star

我的KPOINTS
Auto-generation
0
Gamma
2  1  2
0  0  0
若是把KPOINTS里面的改为2  2  2或者其他的主要是相等的就不会出现VERY BAD NEWS! internal error in subroutine IBZKPT:
Reciprocal lattice and k-lattice belong to different class of lattices.      96
的K点报错,但是还会出现
hit a member that was already found in another star
hit a member that was already found in another star
hit a member that was already found in another star
,若是把INCAR里面设置了ISYM=0就不会出现
hit a member that was already found in another star
hit a member that was already found in another star
hit a member that was already found in another star
这样的错误了,但是,如果把对称性改了,会不会计算结果很离谱啊?期待高手

但是计算的OSZICAR是可以的,显示正常,还有就是要是提交后台运行的话,他会自动终止,出现:       N       E                     dE             d eps       ncg     rms          rms(c)
DAV:   1     0.284985510380E+03    0.28499E+03   -0.13981E+04   328   0.151E+03
p0_30267:  p4_error: interrupt SIGx: 1
要是不提交后台运行,不会出现这样的错误。这事为什么啊?期待高手回答

楼上的,谢谢你,可是晶格的倒数之比应该是2x1x2吧?

呵呵,可能你没弄明白,我仔细的计算了一下你的晶格常数 a:b=7:5,你可以设置KPOINTS里面的结果为:4x5x4。这次肯定没有问题了

遇到过同样的问题,呵呵,你的问题就是正空间到倒空间的转变没有弄明白,有一个倒数关系,你的K点应该是1x2x1,or 2x4x2这样的形式。

谢谢您,不过问题还是没有解决!
