#!/bin/bash echo -e "establish a supercell from a unit cell" echo -e "Please input the number of the atoms:\c" read atomnumber echo -e "Please input the types of the atoms:\c" read atomtypes echo -e "Please in put the lattice paremeters\na b c cos(ab) cos(bc) cos(ac)" read a b c Calpha Cbeta Cgamma echo -e "please input the rule for supercell\n x1 y2 z3 " read x1 y2 z3 if [ -f input.txt ];then echo "exist" rm -f input.txt fi let kcount=0 let increase=1 while [ $kcount -ne $atomnumber ]; do echo -e "please input the $kcount atom x, y, z coordinates...\n atom type x y z" read atomtype x y z echo -e "$x $y $z\n" xx=$x; yy=$y; zz=$z kcountx=0 while [ $kcountx -lt $x1 ]; do kcounty=0 while [ $kcounty -lt $y2 ]; do kcountz=0 while [ $kcountz -lt $z3 ]; do x=`echo $x1 $kcountx $xx|awk '{printf "%0.8f\n", 1/$1*$2+$3/$1}'` y=`echo $y2 $kcounty $a $b $yy|awk '{printf "%0.8f\n", 1/$1*$2*$4/$3+$5/$1}'` z=`echo $z3 $kcountz $a $c $zz|awk '{printf "%0.8f\n", 1/$1*$2*$4/$3+$5/$1}'` echo "$x $y $z" kcountz=$((kcountz+1)); echo $atomtype $x $y $z >>input.txt done kcounty=$((kcounty+1)); done kcountx=$((kcountx+1)); done let kcount=kcount+1 done 直接cp在成.sh文件，按赵提示运行就可以构造任意大小到超晶报 有喜欢PWscf计算的虫子可以 交流交流 本人的 E－mail: liubaoshun@126.com |
