Default: VACPOTFLAT = 0.1
Description: Maximum permissible 2D-averaged electric field for a region considered to be field-free in eV/Å.
A region of space is considered to be field-free if the 2D-averaged electric field (LVACPOTAV=True) is smaller than VACPOTFLAT.
| Tip: Increase VACPOTFLAT for a quick estimation of the vacuum potential and decrease for a precise value. If the cell is large and EDIFF small, the final result of LVACPOTAV should be independent of VACPOTFLAT. |
