[Pw_forum] vc-relax - Convergence Problems

1. You have 32 atoms: seems like you don't have any vacancy in the
system (forgive me if I am wrong)
2. You should have more significant numbers for coordinates of Sb.
3. Before doing a vc-relax with impurities, I would start with
optimizing structure first.

Hope those help!
