| FORCE_PAW | |
| Use the GAPW scheme also for atoms with soft basis sets, i.e. the local densities are computed even if hard and soft should be equal. If this keyword is not set to true, those atoms with soft basis sets are treated by a GPW scheme, i.e. the corresponding density contribution goes on the global grid and is expanded in PW. This option nullifies the effect of the GPW_TYPE in the atomic KIND | |
