Detailed Description

This ScalarFunction subclass represents a function that returns a constant value everywhere in space and time.

Constructor & Destructor Documentation

ConstantScalarFunction::ConstantScalarFunction ( Real a_value )

explicit

Creates a constant scalar function returning the given value.

Parameters

a_value The value returned by the function.

ConstantScalarFunction::~ConstantScalarFunction ( )

Destructor.

Real ConstantScalarFunction::operator()	(	const RealVect &	a_x,
		Real	a_t
	)		const

virtual

Override this method to evaluate this function at the given point in space and time.

Parameters

a_x	A point in -dimensional space.
a_t	The time at which the function is to be evaluated.

Real ConstantScalarFunction::derivative	(	const IntVect &	a_order,
		const RealVect &	a_x,
		Real	a_t
	)		const

virtual

Override this method to evaluate the given partial derivative of the function at the given point in space and time.

Parameters

a_order	A multi-index identifying the order(s) of the partial derivative of the function to be evaluated.
a_x	A point in -dimensional space.
a_t	The time at which the derivative is to be evaluated.

Reimplemented from ScalarFunction.
