[Pw_forum] CNT unit cell vectors

[Mahmoud Hammouri]

Thank you Wang for you answer. I found carbon nanotubes input files using ibrav=6 and others using ibrav=8, so how can I which one I should use? Another question: what is the difference between scf and relax calculations since all DFT are self consistent?
