template<class PointType >

double advective_flux	(	Field< 3, FieldValue< 3 >::VectorFixed > &	advection_coef,
		Range< PointType >	pts,
		ElQ< Scalar > &	JxW,
		ElQ< Vector >	normal
	)

Computes advective flux.

Parameters

advection_coef	Advection vector.
pts	Quadrature points.
JxW	JxW accessor.
normal	normalW accessor.

Returns

double

DG_penalty_boundary()

double DG_penalty_boundary	(	Side	side,
		const double &	diff_delta,
		const double	flux,
		const double	alpha
	)

Computes the penalty parameter of the DG method on a given boundary edge.

Assumption is that the edge consists of only 1 side.

Parameters

side	The boundary side.
diff_delta	Average normal dispersivity K*n.n computed by diffusion_delta()
ad_vector	Advection vector.
alpha	Penalty parameter that influences the continuity of the solution (large value=more continuity).

		const arma::vec3 &	nv
	)

Computes average normal diffusivity over a set of points.

Parameters

diff_coef	Diffusion tensor.
pts	Points.
nv	Normal vector.

Returns
