Detailed Description

template<class ctype, int grid1Dim, int grid2Dim, int dimworld>
class Dune::GridGlue::Merger< ctype, grid1Dim, grid2Dim, dimworld >

Abstract base for all classes that take extracted grids and build sets of intersections.

Template Parameters

ctype	The type used for coordinates (assumed to be the same for both grids)
grid1Dim	Dimension of the grid1 grid
grid2Dim	Dimension of the grid2 grid
dimworld	Dimension of the world space where the coupling takes place

Member Function Documentation

build()

template<class ctype , int grid1Dim, int grid2Dim, int dimworld>

virtual void Dune::GridGlue::Merger< ctype, grid1Dim, grid2Dim, dimworld >::build ( const std::vector< Dune::FieldVector< ctype, dimworld > > &  grid1_coords, const std::vector< unsigned int > &  grid1_elements, const std::vector< Dune::GeometryType > &  grid1_element_types, const std::vector< Dune::FieldVector< ctype, dimworld > > &  grid2_coords, const std::vector< unsigned int > &  grid2_elements, const std::vector< Dune::GeometryType > &  grid2_element_types  )

pure virtual

builds the merged grid

Note that the indices are used consequently throughout the whole class interface just like they are introduced here.

Parameters

grid1_coords	the grid1 vertices' coordinates ordered like e.g. in 3D x_0 y_0 z_0 x_1 y_1 ... y_(n-1) z_(n-1)
grid1_elements	array with all grid1 elements represented as corner indices into grid1_coords
grid1_element_types	array with the GeometryType of the elements listed grid1_elements
grid2_coords	the grid2 vertices' coordinates ordered like e.g. in 3D x_0 y_0 z_0 x_1 y_1 ... y_(n-1) z_(n-1)
grid2_elements	just like with the grid1_elements and grid1_coords
grid2_element_types	array with the GeometryType of the elements listed grid2_elements

Implemented in Dune::GridGlue::StandardMerge< T, grid1Dim, grid2Dim, dimworld >.

intersectionList()

template<class ctype , int grid1Dim, int grid2Dim, int dimworld>

virtual std::shared_ptr< IntersectionList > Dune::GridGlue::Merger< ctype, grid1Dim, grid2Dim, dimworld >::intersectionList ( ) const

pure virtual

list of intersections

Note

only valid after build() was called

Implemented in Dune::GridGlue::StandardMerge< T, grid1Dim, grid2Dim, dimworld >, Dune::GridGlue::StandardMerge< double, dim, dim, dimworld >, Dune::GridGlue::StandardMerge< double, dimworld-1, dimworld-1, dimworld >, and Dune::GridGlue::StandardMerge< double, dim1, dim2, dimworld >.
