template<class G, class RT>

void Dune::ElementGroundwaterEstimator< G, RT >::estimate	(	const Entity &	e,
		RT &	elementpart
	)			`[inline]`

Evaluate element part of error estimator.

This functions is only implemented for P1 elements ! This function assumes a conforming mesh !

Parameters:

`[in]`	e	a codim 0 entity reference
`[out]`	elementpart	element part of error estimator

template<class G, class RT>

void Dune::ElementGroundwaterEstimator< G, RT >::estimate	(	const Entity &	e,
		const IntersectionIterator &	it,
		const EEntityPointer &	outside,
		RT	facefluxK[],
		RT	facefluxN[],
		RT &	facefactor,
		typename BoundaryConditions::Flags &	facebctype,
		bool	first
	)			`[inline]`

Evaluate face part of error estimator for a given face.

This functions is only implemented for P1 elements ! This function assumes a conforming mesh !

Parameters:

`[in]`	e	a codim 0 entity reference
`[in]`	it	an intersection iterator started from e
`[out]`	facefluxK	the faceflux is evaluated as Sum facefluxK[i]*coeff[i] with coefficients of finite element function
`[out]`	facefluxN	same for neighbor of the given face
`[out]`	facefactor	factor by which difference of fluxes has to be multiplied
`[out]`	facebctype	if bctype is neumann then facefluxN[0] contains neumann value
