这是我仿照侯博的Cu的计算例子文件写的脚步,包括ESPRESSO 5.0.2 pp/examples/example02或老版的example08计算费米面的例子文件中非自洽计算部分均无需设定smearing。Sc是金属。 Sc.pbe-sp-hgh.UPF是模守恒赝势,之前用的是超软赝势Sc.pbe-nsp-van.UPF:ecutwfc = 90, ecutrho = 960.00。结果同上,仍然是不收敛。 赝势网址如下: http://www.quantum-espresso.org/ ... m_k=&origin_id= #######################【自洽计算,产生$name.scf.out_$a文件,即Sc.scf.out_0文件】################################ self-consistent calculation -Non-Spin-Polarised case #【为什么要进行自洽计算,目的是.....】 for a in 0 do cat > $name.scf.in_$a << EOF &control calculation = 'scf' restart_mode='from_scratch', prefix='$name', pseudo_dir = '$PSEUDO_DIR/', outdir='$TMP_DIR/' tstress=.t., tprnfor=.t. / &system ibrav=0, nat=2, ntyp=1, ecutwfc=90.0, ecutrho = 360.0 occupations='smearing', smearing='methfessel-paxton', degauss=0.02 / &electrons conv_thr = 1.0d-8 mixing_beta = 0.7 / #&CELL #cell_dynamics= 'damp-pr' # press=$a #/ ATOMIC_SPECIES Sc 44.9559 Sc.pbe-nsp-van.UPF CELL_PARAMETERS {bohr} 6.254820382 0.00000000 0.00000000 -3.127410191 5.41683334 0.00000000 0.000000000 0.00000000 9.958412336 ATOMIC_POSITIONS {crystal} Sc 0.3333333333333286 0.6666666666666714 0.2500000000000000 Sc 0.6666666666666714 0.3333333333333286 0.7500000000000000 K_POINTS {automatic} 8 8 4 0 0 0 EOF $PW_ROOT/pw.x < $name.scf.in_$a >$name.scf.out_$a done #########【准备并用kvecs_FS.x程序产生计算费米面要用到的密集网格k点,各k点坐标存储于文件kves_$Sysname中】############# #kves_$Sysname的定义见keves_FS.f源程序 # prepare input file $name.fs.in # Sysname='$name' Calc_Type='FS' nabc=' 16 16 8' #【k点分割数与一般的计算相同吗】 n_start=3 n_last=6 # E_Fermi=`grep Fermi $name.scf.out_$a| cut-c 26-36` #【$name.scf.out_$a,由前一步自洽计算产生】 a1=`grep 'b(1)' $name.scf.out_$a| cut -c 24-54` a2=`grep 'b(2)' $name.scf.out_$a| cut -c 24-54` a3=`grep 'b(3)' $name.scf.out_$a| cut -c 24-54` cat > kvecs_FS.in < $a2 $a3 $nabc $Sysname EOF kvecs_Fs.x < kvecs_FS.in >kvecs_FS.out #########################【非自洽计算,产生文件$name.nscf.out】######################## # 进行一次非自洽计算,计算上一步产生的各k点的本征值; cat > $name.nscf.in << EOF &control calculation='nscf', prefix='$name' pseudo_dir = '$PSEUDO_DIR/', outdir='$TMP_DIR/' / &system ibrav = 0, nat= 2, ntyp= 1, ecutwfc = 90, ecutrho = 400.00, # occupations='smearing', #【非自洽计算这些参数均无必要】 # smearing='methfessel-paxton', # degauss=0.02 nbnd=8 #【一定要定义nbnd吗?默认值是.....】 / &electrons diagonalization='cg' mixing_beta = 0.7 conv_thr = 1.0d-10 #【1.0d-10与1.0e-10含义一样吗】 / #【diagonalization='cg' 英文注释:conjugate-gradient-like band-by-band diagonalization.
