Hi<br>I am studying a supercell for Ni with 64 atoms. while specifying nbnd how much i select i am not sure. if i go by document PW.html it says that for metal it should be nelec/2 + 20 %. then should i take nbnd = 400. also it says minimum 4 more i.e. should i take nbnd = 330. Thanks in advance.<br>
