Dune::RatioIndicator< Grid > Class Template Reference

Class defining an indicator for grid remeshing regarding the edge length ratio. By default, we take 2x length of the longest edge contained in the interface as maximal edge length and 0.5x length of the shortest edge as minimal edge length. More...

Detailed Description

template<class Grid>
class Dune::RatioIndicator< Grid >

Class defining an indicator for grid remeshing regarding the edge length ratio. By default, we take 2x length of the longest edge contained in the interface as maximal edge length and 0.5x length of the shortest edge as minimal edge length.

Constructor & Destructor Documentation

RatioIndicator()

template<class Grid >

Dune::RatioIndicator< Grid >::RatioIndicator ( ctype  h = 0.0, ctype  distProportion = 1.0, ctype  factor = 1.0  )

inline

Calculates the indicator for each grid cell.

Parameters

h	The objective edge length (aims at edge length in [h/4, 2*h]).
distProportion	Cells with distance to interface of value greater than distProportion * max(dist) are refined to ...
factor	... edge length in [factor * minH, factor * maxH].

Member Function Documentation

init()

template<class Grid >

void Dune::RatioIndicator< Grid >::init ( const Grid &  grid )

inline

Calculates minH_ and maxH_ for the current interface edge length and sets factor_ to maxh / minh.

Referenced by Dune::MMesh< HostGrid, dim >::MMesh().

operator()()

template<class Grid >

template<class Element >

int Dune::RatioIndicator< Grid >::operator() ( const Element &  element ) const

inline

Function call operator to return mark.

Returns

1 if an element should be refined, -1 if an element should be coarsened, 0 otherwise.
