剛學(xué)習(xí)使用wien2k,按照UG的指導(dǎo)進(jìn)行體積優(yōu)化時(shí)出現(xiàn)問(wèn)題: 我的optimize.job文件如下: 運(yùn)行后僅僅得到一個(gè)數(shù)據(jù)點(diǎn),為什么? 正常的是應(yīng)該有5個(gè)點(diǎn),并連成曲線(xiàn)。 請(qǐng)幫助!謝謝! ~~~~~~~~~~ #!/bin/csh -f # Modify this script according to your needs: # Uncomment one of the lines ... to adjust # starting electron density: either use # clmextrapol # or a clmsum file from a previous run (with smaller k-mesh,...) # convergence criteria, # spin-polarization (change run_lapw to runsp_lapw) # activate min_lapw # modify the save_lapw command if (-e TiC.clmsum && ! -z TiC.clmsum) then x dstart -super endif if (-e TiC.clmup && ! -z TiC.clmup) then x dstart -super -up x dstart -super -dn endif foreach i ( \ TiC_vol_-10.0 \ TiC_vol__-5.0 \ TiC_vol___0.0 \ TiC_vol___5.0 \ TiC_vol__10.0 \ ) rm TiC.struct # NFS-bug cp $i.struct TiC.struct # Please uncomment and adapt any of the lines below according to your needs # if you have a previous optimize-run: # cp $i.clmsum TiC.clmsum # cp $i.clmup TiC.clmup # cp $i.clmdn TiC.clmdn # if you want to start with dstart: # x dstart # -c # x dstart -up # -c # x dstart -dn # -c # recommended option: use charge extrapolation clmextrapol_lapw if (-e TiC.clmup && ! -z TiC.clmup) then clmextrapol_lapw -up clmextrapol_lapw -dn endif run_lapw -ec 0.0001 # -p -it # runsp_lapw -ec 0.0001 # min -I -j "run_lapw -I -fc 1.0 -i 40 " set stat = $status if ($stat) then echo "ERROR status in" $i exit 1 endif save_lapw ${i} # save_lapw -f -d XXX $i end ~~~~~~~~~~ 網(wǎng)站上給出的optimize.job文件如下: ~~~~~~~~~~ #!/bin/csh -f # Modify this script according to your needs: # Uncomment one of the lines ... # Change run_lapw to runsp_lapw or use different convergence criterium # Change save_lapw -d XXX foreach i ( \ TiC_vol_-10.0 \ TiC_vol__-5.0 \ TiC_vol___0.0 \ TiC_vol___5.0 \ TiC_vol__10.0 \ ) cp $i.struct TiC.struct # cp $i.clmsum TiC.clmsum x dstart # run_lapw -ec 0.0001 -in1new 3 -in1orig -renorm run_lapw -ec 0.0001 set stat = $status if ($stat) then echo "ERROR status in" $i exit 1 endif save_lapw $i # save_lapw -f -d XXX $i end ~~~~~~~~~~ |

請(qǐng)問(wèn)樓主,計(jì)算物質(zhì)存在反演時(shí),進(jìn)行結(jié)構(gòu)優(yōu)化,optimize.job文件修改只是修改這兩個(gè)地方,#if you want to start with dstart : x dstart -c ,還有一個(gè)地方就是run_lapw -cc 0.0001 -p 。但是,為什么回出現(xiàn)下面這個(gè)錯(cuò)誤呢?error command: ~/lapw1cpara -c lapw1.def failed。而且是有的結(jié)構(gòu)會(huì)出現(xiàn)這個(gè)錯(cuò)誤有的不會(huì)。樓主有沒(méi)有遇到這個(gè)問(wèn)題,或者請(qǐng)告知,體積優(yōu)化時(shí),optimize.job只這樣修改這兩個(gè)地方對(duì)不對(duì)?謝謝 |
