Your structure is wrong. Al2O3 has a rhombohedral lattice. Please read in the UG (struct file) how to specify such a structure. (also w2web gives you hints about that): You need to give the hexagonal unit cell (as you did), but the positions of the atoms in rhombohedral coordinates (you did n

Dear Wien2k users I am trying to do PBE calculations for Al2O3 by following steps 1. Genrate the structure Al2O3 Space Group :(167) Lattice Parameters: a=4.757 b=4.757 c=12.988 alpha=90=beta gamma=120 Positions : Al(0,0,0.35218) O(0.30625,0,1/4) Reduce RMT by 0% : This reduces
