Detailed Description

Base class for internal data. Adds data for second derivatives to Mapping::InternalDataBase()

For information about the general purpose of this class, see the documentation of the base class.

Constructor & Destructor Documentation

template<int , int >

virtual FiniteElement< int, int >::InternalDataBase::~InternalDataBase ( )

virtual

Destructor. Needed to avoid memory leaks with difference quotients.

template<int , int >

void FiniteElement< int, int >::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.

template<int , int >

std::vector<FEValues<dim,spacedim>*> FiniteElement< int, int >::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.
