使用orca计算过渡金属的epr谱,准备先使用较小基组泛函优化结构,再使用大基组计算epr。但是在优化结构部分报错,并且不收敛。该怎么解决呢?
输入文件如下:
! medium-opt
%MaxCore 2500
%pal nprocs 12 end
* xyz -1 2
Ti 0.00500000 0.00500000 0.01200000
Ni 2.31700000 2.33100000 1.55300000
... ...
*
报错内容如下:
job aborted:
[ranks] message
[0-11] process exited without calling finalize
---- error analysis -----
[0-11] on DESKTOP-AGRA501
C:\Orca\orca_scf_mpi.exe ended prematurely and may have crashed. exit code 125
---- error analysis -----

.... aborting the run
并且提示SCF不收敛:
This wavefunction IS NOT CONVERGED!
And it is 'too far' from meeting the convergence thresholds.
使用组合命令quick-SCF、调用BP86和6-31g基组,也出现相同的报错。添加slowconv阻尼似乎也无法解决收敛问题。
