Constructor & Destructor Documentation

HeatEqBoundaryNeumann::HeatEqBoundaryNeumann

(

)

Class constructor.

Creates a neumann boundary conditions class, the constructor specifies the type as "neumann". It also sets q_constant to zero.

Member Function Documentation

Number HeatEqBoundaryNeumann::q	(	const Point &	p,
		const Real	t
	)		[virtual]

A virtual function for returning the flux.

By default this function returns a constant value defined in the q_constant attribute. If constant flux is to be used then only q_constant must be changed (it is zero by default). To create a non-constant flux a derived class should be created that inherts this class. This q() function should then be defined in this new class to return the desired flux value.

Reimplemented from SlaughterFEM::HeatEqBoundaryBase.

void SlaughterFEM::HeatEqBoundaryNeumann::value	(	DenseVector< Number > &	output,
		const Point &	p,
		const Real	t
	)		[inline, protected, virtual]

Computes and returns the heat flux.

This returns the flux value that is computed by the q function that may be customized. This member is used by the HeatEq class thus is protected.

Parameters:

output	A reference to the vector that stores the stores the computed flux
p	A libMesh point
t	The time
