Constructor & Destructor Documentation

template<int dim, int spacedim = dim>

virtual FiniteElement< dim, spacedim >::InternalDataBase::~InternalDataBase

(

)

[virtual]

Destructor. Needed to avoid memory leaks with difference quotients.

Reimplemented from Mapping< dim, spacedim >::InternalDataBase.

Member Function Documentation

template<int dim, int spacedim = dim>

void FiniteElement< dim, spacedim >::InternalDataBase::initialize_2nd	(	const FiniteElement< dim, spacedim > *	element,
		const Mapping< dim, spacedim > &	mapping,
		const Quadrature< dim > &	quadrature
	)

Initialize some pointers used in the computation of second derivatives by finite differencing of gradients.

Member Data Documentation

template<int dim, int spacedim = dim>

std::vector<FEValues<dim,spacedim>*> FiniteElement< dim, spacedim >::InternalDataBase::differences

Storage for FEValues objects needed to approximate second derivatives.

The ordering is p+hx, p+hy, p+hz, p-hx, p-hy, p-hz, where unused entries in lower dimensions are missing.
