ParabolicEquation::BoundaryCache Struct Reference

Defining boundary conditions. More...

#include <variationalfunctional.hh>

Detailed Description

Defining boundary conditions.

This evaluation cache concept defines the interface that is accessed by the assembler. This is not a base class, only a documentation!

Different objects have to be independent w.r.t. parallel execution.

FaceIterator

typedef AnsatzVars::Grid::LeafIntersectionIterator ParabolicEquation::BoundaryCache::FaceIterator

Type of the Face Information.

Definition at line 935 of file variationalfunctional.hh.

Constructor & Destructor Documentation

BoundaryCache()

ParabolicEquation::BoundaryCache::BoundaryCache ( Functional const &  f, typename OriginVars::VariableSet const &  u, int const  flags = 7  )

inline

Constructs an evaluation cache from the associated functional f_, a point of linearization u_, and flags from the assembler

Parameters

[in]

flags

A bit field that tells the cache what parts are to be assembled. If flags & Assembler::RHS is false, d1() will never be called. If flags & Assembler::VALUE is false, d0() will never be called, and d2() will never be called if flags & Assembler::MATRIX is false. This information can be used to restrict the computation to the actually required quantities.

b2()

template<int row, int col, int dim>

		VariationalArg< Scalar, dim > const &	argA
	)		const

This method need only be defined for values of row/col for which B2<row,col>::present is true.

		VariationalArg< Scalar, dim > const &	argA
	)		const

This method need only be defined for values of row/col for which D2<row,col>::present is true.

evaluateAt()

template<class Position , class Evaluators >

void ParabolicEquation::BoundaryCache::evaluateAt ( Position const &  x, Evaluators const &  evaluators  )

inline

Construct all data that is constant at one point. Default implementation in EvalBaseCache: assert(false)

Definition at line 960 of file variationalfunctional.hh.

moveTo()

template<class FaceIterator >

void ParabolicEquation::BoundaryCache::moveTo ( FaceIterator const &  )

inline

Construct all data that is constant in an entity. Default implementation in EvalBaseCache: does nothing
