結(jié)構(gòu)優(yōu)化出錯
|

用abinit優(yōu)化結(jié)構(gòu)之后 原子位置變得雜亂無章,我使用http://www.crystallography.net/得到的cif,用cell2abinit來得到abinit的結(jié)構(gòu)輸入信息的 我的輸入文件,大家?guī)臀铱纯从惺裁磫栴},我原來是用原包做的 也是雜亂無章,現(xiàn)在換成單包 并且加了spgroup還是這樣: optcell 2 ionmov 3 dilatmx 1.2 #Gives the maximal permitted scaling of the lattice parameters when the cell shape and dimension is varied tolmxf 1.0d-8 #TOLerance on the MaXimal Force toldfe 1.0d-9 # Tolerance on the difference of total energy ntime 200 kptopt 1 #nband 30 ecut 24 ecutsm 0.5 #Definition of the k-point grid nstep 100 ngkpt 10 10 5 nshiftk 1 shiftk 0.5 0.5 0.5 prtcif 1 prtgeo 0 # Definition of the unit cell #The length of the primitive vectors # 1 Bohr=0.5291772108 Angstroms #acell 5.585000 5.585000 2.908000 Angstroms acell 10.990647 10.990647 21.108241 rprim 1.000000 0.000000 0.000000 0.000000 1.000000 0.000000 0.000000 0.000000 1.000000 #Definition of the atom types # 8 kind of atoms # ['S', 'Ag', 'In'] ntypat 3 znucl 16 47 49 #Definition of tha atoms natom 16 typat 1 1 1 1 1 1 1 1 2 2 2 2 3 3 3 3 xred 0.25 0.25 0.125 -0.25 -0.25 0.125 0.25 0.25 0.625 0.25 -0.25 -0.125 0.75 0.25 0.375 -0.25 0.25 -0.125 0.25 0.75 0.375 0.75 -0.25 0.625 0.0 0.0 0.0 0.5 0.5 0.5 0.5 0.0 0.75 1.0 0.5 1.25 0.0 0.0 0.5 0.5 0.5 1.0 0.5 0.0 0.25 1.0 0.5 0.75 spgroup 122 chkprim 0 |
