>                          I am trying to simulate supercell of ZnO zincblende structure with 56 atoms. I have checked the structure with Xcrysden and it is right. But the problem is after performing some electronic cycle the speed becomes very slow and the calculations are stuck. When I reduce the "ecut" value it performs some ionic relaxation step but the same problem come after some ionic relaxation steps. Can anybody please help whats wrong with the calculation?
