Possible enhancements:: generalize to time-dependent conditions.

Member Function Documentation

void applyBeforeApplying ( TridiagonalOperator & ) const

virtual

This method modifies an operator $ L $ before it is applied to an array $ u $ so that $ v = Lu $ will satisfy the given condition.

Implements BoundaryCondition< TridiagonalOperator >.

void applyAfterApplying ( Array & ) const

virtual

This method modifies an array $ u $ so that it satisfies the given condition.

Implements BoundaryCondition< TridiagonalOperator >.

void applyBeforeSolving	(	TridiagonalOperator &	,
		Array &	rhs
	)		const

virtual

This method modifies an operator $ L $ before the linear system $ Lu' = u $ is solved so that $ u' $ will satisfy the given condition.

Implements BoundaryCondition< TridiagonalOperator >.

void applyAfterSolving ( Array & ) const

virtual

This method modifies an array $ u $ so that it satisfies the given condition.

Implements BoundaryCondition< TridiagonalOperator >.

void setTime ( Time t )

virtual

This method sets the current time for time-dependent boundary conditions.

Implements BoundaryCondition< TridiagonalOperator >.
