Detailed Description

template<class Implementation>
class Dune::ACFem::BoundaryIndicatorInterface< Implementation >

A simple interface class for a boundary-indicator.

Boundary-indicators attach a boolean to each boundary-intersection. In that way, they model the characteristic function for dedicated subsets of the boundary of the computational domain. Usually they are used to distinguish beteen different boundary conditions. However, they do not carry any interpretation, their task is to group parts of the boundray together.

Bug:

This should probably be changed in a way that there is only one classificator class per condition; complex operations with indicators could then be simplified at compile time (the classificators would be required to do the same if they belong to the same class). The BoundaryIdClassificator is one example ATM where this is NOT the case.

template<class Intersection >

bool Dune::ACFem::BoundaryIndicatorInterface< Implementation >::applies ( const Intersection &  intersection ) const

inline

Classify a boundary facet.

Parameters

[in]

intersection

The current intersection. It is up to the implementation to take the information from intersection (e.g. coordinates or the id from the macro triangulation).

Returns

true to indicate that intersection belongs to the boundary segment of interest.
