Dear Developers and Users,<br>I was calculating the band structure of ZB-InN using 'hse' hybrid functional. It gives the reasonable band gap opening but the run was goes on<br>and can't stop. Here i am giving some sort of it's output.<br>
Firstly sorry for giving long output data...but have no choice...<br>Please give me a ray of hope to converges of hse calculation in pw.x.<br><font size="4">input....</font><br><br>&control<br> calculation = 'scf'<br>
