Try to decrease it to 0.1 or so

I would disable this, since you are not having a layered material

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
