[Pw_forum] Binding energy of Cu at CNT

[chengyu yang]

Hi all,
    It seems that my script for single cu atom is wrong in case 2, cause I
got a total energy of -212, which is far away from the usual value. The
script for case 1 seems to be more correct, but I don't know how to achieve
enough accuracy...... Thank you!
