| 我用tnlo_2計(jì)算一層平面結(jié)構(gòu)時(shí)是OK的 但在改變?cè)游恢檬蛊溆悬c(diǎn)皺摺時(shí)就無法計(jì)算了 err檔中?K沒有對(duì)錯(cuò)誤的敘述 請(qǐng)問該怎麼辦呢 |

It could be an Abinit problem, even though I still think it is higher possible raised from the old version of MPI. If you wanna calculate the 3rd-order deviation of energy ( anharmonic phonon), why not giving a try to Quantum-ESPRESSO? It is normally stable for response function issues. |

看樓主的語(yǔ)言習(xí)慣是港臺(tái)的,我還是用英語(yǔ)回復(fù)好了。 The error info can be found at the end of xxx.log file if you ran Abinit with command: abinit < xxx.files >& xxx.log, otherwise, it displays in your terminal. I am not sure which kind of "error" you met, or what means "cannot calculate". By guessing, displacements of ion(s) broke the symmetry, thus the convergence of response function may become more difficult. |

Actually, the error info you provided was not really the proper one, since it was just a stop signal from MPI code, instead of that from Abinit. Why don't you attach your full log or output file here? You can edit your first post and upload the file as accessory. Further, you may download my tutorial about Abinit from the ??????? broad. That will give you some idea for finding error info from Abinit. ?????????δ???????????????????????MPI??????????????????Abinit??? ??????log???????????????????????Σ????????????????????????? ????????????????????????????Abinit??????????????β???Abinit?????????? |
