= PE | for GGA pseudopotentials |
Definition: Set the default exchange-correlation functional.
The functional specified by LEXCH was used as a reference when the PAW potential was created. The transferability of PAW potentials to other exchange-correlation functionals is quite good. So, the functional used during the calculation can be freely adjusted (despite the very prominent warning in the stdout).
