Section KE_GGA

• Uses one of the KE_GGA functionals (optimized versions of some of these functionals might be available outside this section). These functionals are needed for the computation of the kinetic energy in the Kim-Gordon method.  [Edit]

  SECTION_PARAMETERS
  	&KE_GGA {Logical}
  	activates the functional  [Edit]
  	This keyword cannot be repeated and it expects precisely one logical.
  	The lone keyword behaves as a switch to .TRUE.
  	Default value: .FALSE.

  FUNCTIONAL
  	FUNCTIONAL {Keyword}
  	Which one of the KE_GGA functionals should be used  [Edit]
  	This keyword cannot be repeated and it expects precisely one keyword.
  	Default value: LLP
