Member Function Documentation

Size BALL::PeriodicBoundary::addSolvent ( const String & filename ) const

Fill the defined box with a solvent. This method fills the defined box with solvent molecules. If no box is defined, no solvent is added. The neccessary solvent box template is either taken from the options (solvent_file) or a default is assumed.

: This method replicates the solvent box starting at the box origin in all three dimensions and removes all solvent molecules that are within solvent_distance of a solute molecule or outside the periodic box.

: The method returns the number of inserted solvent molecules. All solvent molecules are marked as such by setting their property Molecule::PROPERTY__PERIODIC_BOX_SOLVENT .

See also:: removeSolvent

virtual void BALL::PeriodicBoundary::clear ( ) [virtual]

Clear method

void BALL::PeriodicBoundary::disable ( )

Disable periodic boundary conditions.

void BALL::PeriodicBoundary::enable ( )

Enable periodic boundary conditions.

Size BALL::PeriodicBoundary::generateMoleculesVector ( )

Generate the vector of molecules of the system

SimpleBox3 BALL::PeriodicBoundary::getBox ( ) const

Retrieve the box dimensions.

bool BALL::PeriodicBoundary::isEnabled ( ) const

Returns true if the periodic boundary is enabled

See also:: enable; disable

PeriodicBoundary& BALL::PeriodicBoundary::operator= ( const PeriodicBoundary & periodic_boundary )

Assignment operator.

Size BALL::PeriodicBoundary::removeSolvent ( ) const

Removes all solvent molecules This method removes all molecules that have the property Molecule::PROPERTY__PERIODIC_BOX_SOLVENT set from the force field's system. The number of removed solvent molecules is returned.
