[求助] 运行vasp后报错 已有1人参与

我的体系比较大,有96个原子,所以我用了实空间,请大家帮我看看报错信息,

这个原因很多,可能的改正方法:
1) 快速算法不合适,修改ALGO;
The diagonalization algorithm is not stable for your system
-> Change ALGO = Normal or ALGO = Fast in your INCAR file

2) 构型不合理,修改离子算法
Your geometry is not reasonable. Maybe your initial structure or the algorithm handling ion relaxation is giving a bad structure
-> Switch to a different ion relaxation scheme (IBRION line in your INCAR)
-> Reduce the step size of the first step by reducing the POTIM value in your INCAR

3) Problem with your LAPACK installation
-> Use the LAPACK routines that came with the VASP library tar-file (vasp.4.lib)

4) If the error does not go away even if you already did the thing described in part 1 (ALGO change), then there may be a problem with LAPACK.
-> Disable the calls to ZHEGV subroutine. This can be done by commenting the line

# define USE_ZHEEVX
in subroutines davidson.F, subrot.F and wavpre_noio.F.
-> Recompile VASP after you changed the subroutines

5) I was using 32 cpu when I took the error and the error disappeared for 16 cpu.

6) Please try if it works by adding "LSCALAPACK = .FALSE." in your INCAR.

7) We found that there's an error in the way VASP calculates k-points when using the Monkhorst-pack scheme and that the problem would be fixed if we used Gamma centered instead.
