(Late===If I m not wrong.) But the calculations are quite well with ibrav = 2 (with two atoms of Zn and O) but this problem occurs when I use ibrav = 1 and eight atoms (4 Zn and 3 O and 1 S.)<br>Where is the problem I can not find it. We work with simple FCC alloys by giving 4 atoms position using ibrav =1 . It also work wells. But in case of ZB structure it creates problem<br><br>Muhammad Zafar<br>
