[QE-users] relax does not converge

2021-11-18 Thread LEUNG Clarence
Dear QE users, The vc-relax of unitcell of LiFePO4 with 28 atoms is converged. Then, I build 2*2 supercell of LiFePO4 with 112 atoms and do vc-relax with the same computational setting. It does not converge with very large estimated scf accuracy and Total force (more than 10 thousands). I ha
