Detailed Description

MMFF94 force field class.

Member Function Documentation

bool BALL::MMFF94::checkAtomType ( Atom & atom )

Check wheter the atoms type is valid.

If not, add it to unassigned atoms.

double BALL::MMFF94::getNonbondedEnergy ( ) const

Return the nonbonded contribution to the total energy.

This energy comprises Van der Waals energy, hydrogen bond energy, and elesctrostatic energy.

double BALL::MMFF94::getTorsionEnergy ( ) const

Return the torsion contribution to the total energy.

This energy comprises proper and improper torsions.

Size BALL::MMFF94::getUpdateFrequency ( ) const [virtual]

Return the recommended number of iterations between updates.

This method return 20 as a default value.

Reimplemented from BALL::ForceField.
