OUTCAR输出为:
Subroutine GETGRP returns: Found  1 space group operations
(whereof  1 operations were pure point group operations)
out of a pool of 16 trial point group operations.


The static configuration has the point symmetry C_1 .

Analysis of symmetry for dynamics (positions and initial velocities):

Subroutine DYNSYM returns: Found  1 space group operations
(whereof  1 operations were pure point group operations)
out of a pool of  1 trial space group operations
(whereof  1 operations were pure point group operations)
and found also     1 'primitive' translations


The dynamic configuration has the point symmetry C_1 .


KPOINTS: kpoints

Automatic generation of k-mesh.

Subroutine IBZKPT returns following result:

进行的是参数a的测定,输入文件如下
SYSTEM = nami
ENCUT = 400
ISMEAR = -5
ISTART = 0
ICHARG= 2
GGA = PB
PREC = Accurate
恳请各位提点意见,谢谢
