【求助】vasp檢驗(yàn)Ti的贗勢(shì)kpoint如何設(shè)置 已有7人參與
|
||
|
大家好,新手請(qǐng)教一個(gè)問(wèn)題。 vasp中檢驗(yàn)Ti的贗勢(shì),結(jié)果不合理。OUTCAR中有個(gè)很大的warning,提示我看了下是說(shuō)k點(diǎn)有問(wèn)題。之前看手冊(cè)上說(shuō)對(duì)于單個(gè)原子只用一個(gè)k點(diǎn)就可以,我測(cè)試過(guò)O、H等都沒(méi)問(wèn)題,可是對(duì)于Ti來(lái)說(shuō)好像有問(wèn)題,請(qǐng)教大家應(yīng)該怎么辦? 我的輸入文件如下 INCAR: SYSTEM=Ti MELMDL=5 ISMEAR=0 SIGMA=0.1 POS: Ti 15 1 0 0 0 1 0 0 0 1 1 Direct 0.00000 0.00000 0.00000 K: Automatic mesh 0 Gamma 1 1 1 0 0 0 POT是用的vasp自帶的PAW_PBE中的Ti OUTCAR中的結(jié)果energy without entropy= -0.988815 ,不合理。 另外有個(gè)很大的警告:Your highest band is occupied at some k-points! Unless you are | | performing a calculation for an insulator or semiconductor, without | | unoccupied bands, you have included TOO FEW BANDS!! Please increase | | the parameter NBANDS in file 'INCAR' to ensure that the highest band | | is unoccupied at all k-points. It is always recommended that one | | include a few unoccupied bands to accellerate the convergence of | | molecular dynamics runs (even for insulators or semiconductors) | | Because the presence of unoccupied bands improves wavefunction | | prediction, and helps to suppress 'band-crossings.' | | Following all k-points will be listed (with the Fermi weights of | | the highest band given in paranthesis) ... : | | | | 1 ( 0.14237) | | | | The total occupancy of band no. 9 is 0.28474 electrons ... | | | 還有個(gè)小的警告:936: WARNING: grid for Broyden might be to small 這是vasp自帶的贗勢(shì),怎么會(huì)有問(wèn)題呢,如果真有問(wèn)題,那接下來(lái)還怎么繼續(xù)做下去啊。請(qǐng)大家?guī)兔Ψ治鲆幌掳。≈x謝各位!
