Detailed Description

Abstract base class of pair-potential dispersion correction methods.

Member Function Documentation

energyAndGrad()

virtual double VanDerWaals::energyAndGrad ( std::vector< Atom > &  atoms, const double  scaleFac, matrix3<> *  E_RRT = 0  ) const

pure virtual

Van der Waal correction energy for a collection of discrete atoms at fixed locations. Corresponding forces should be accumulated to Atom::force for each atom. If E_RRT is non-null, accumulate contributions to the symmetric lattice derivative (stress * volume).

Implemented in VanDerWaalsD3, and VanDerWaalsD2.

getScaleFactor()

virtual double VanDerWaals::getScaleFactor ( string  exCorrName, double  scaleOverride = 0.  ) const

pure virtual

Retrieve the scale factor for a specified exchange-correlation functional. Use scaleOverride, if supplied and supported, to override the functional's default. Quit with an appropriate error message if functional is not parametrized.

Implemented in VanDerWaalsD3, and VanDerWaalsD2.
