【求助成功】計算能帶結(jié)構(gòu)時出現(xiàn)錯誤,請教 已有8人參與

計算六角晶系的能帶結(jié)構(gòu),自洽得到電荷密度已經(jīng)完成,再進(jìn)行第二步,也就是用所得到的電荷密度再重新做非自洽計算時出現(xiàn)問題。 《參考侯老師的文章》:找出簡約布里淵區(qū)的特殊k點(diǎn),編輯了syml文件(利用gk.x產(chǎn)生KPOINTS的輸入文件)。得到KPOINTS文件。同時準(zhǔn)備好計算所需的POTCAR,POSCAR(優(yōu)化以后的),和INCAR(從侯老師的書上改寫得到的)。 進(jìn)行計算,出現(xiàn)錯誤如下: get the following lines in OUTCAR ---------------------------- Analysis of symmetry for dynamics (positions and initial velocities): Subroutine DYNSYM returns: Found 12 space group operations (whereof 6 operations were pure point group operations) out of a pool of 12 trial space group operations (whereof 6 operations were pure point group operations) and found also 1 'primitive' translations The dynamic configuration has the point symmetry C_3v. The point group associated with its full space group is C_6v. -------------------------------------------- it gave the correct space group, but obviously the structure was wrong. I am puzzled now, please help me out, thx! [ Last edited by qiqi2926 on 2010-8-11 at 23:46 ] |

可以用沿高對稱點(diǎn)產(chǎn)生K點(diǎn)的方法試試,另外,能不能把你的gk.x給我發(fā)一份,謝謝! jghe8301@gmail.com |
