Detailed Description

template<class Grid>
class Dune::MMeshImplicitGridFactory< Grid >

specialization of the implicit GridFactory for MMesh

The implicit grid factory for MMesh

Constructor & Destructor Documentation

MMeshImplicitGridFactory()

template<class Grid >

Dune::MMeshImplicitGridFactory< Grid >::MMeshImplicitGridFactory ( )

inline

default constructor

Member Function Documentation

createGrid()

template<class Grid >

std::unique_ptr< Grid > Dune::MMeshImplicitGridFactory< Grid >::createGrid ( )

inline

finalize grid creation and hand over the grid

This version of createGrid is original to the MMesh grid factroy, allowing to specity a grid name.

Returns

a pointer to the newly created grid

insertBoundarySegment()

template<class Grid >

void Dune::MMeshImplicitGridFactory< Grid >::insertBoundarySegment ( const std::vector< unsigned int > &  vertices )

inline

insert boundary segment

Parameters

[in]

vertices

Vertices

References Dune::MMeshImplicitGridFactory< Grid >::dimension.

insertElement()

template<class Grid >

void Dune::MMeshImplicitGridFactory< Grid >::insertElement ( const GeometryType &  type, const std::vector< unsigned int > &  v  )

inline

insert an element into the macro grid

Parameters

[in]	type	GeometryType of the new element
[in]	v	indices of the element vertices (starting with 0)

Note

The implicit grid factory ignores the insertion of specific elements. The CGAL backend constructs the elements by inserting vertices implicitly.

References Dune::MMeshImplicitGridFactory< Grid >::isElement().

insertInterface()

template<class Grid >

void Dune::MMeshImplicitGridFactory< Grid >::insertInterface ( const std::vector< unsigned int > &  vertices, const std::size_t  marker = 1  )

inline

insert an interface into the macro grid

Parameters

[in]	vertices	indices of the interface vertices (starting with 0)
[in]	marker	marker value of the interface segment (default 1)

References Dune::MMeshImplicitGridFactory< Grid >::dimension.

insertionIndex() [1/3]

template<class Grid >

unsigned int Dune::MMeshImplicitGridFactory< Grid >::insertionIndex ( const typename Codim< 0 >::Entity &  entity ) const

inline

return index of inserted vertex within the macro grid

Parameters

[in]

pos

position of the vertex (in world coordinates)

insertionIndex() [2/3]

template<class Grid >

unsigned int Dune::MMeshImplicitGridFactory< Grid >::insertionIndex ( const typename Codim< dimension >::Entity &  entity ) const

inline

return insertion index of entity

Parameters

[in]

entity

Entity

insertionIndex() [3/3]

template<class Grid >

unsigned int Dune::MMeshImplicitGridFactory< Grid >::insertionIndex ( const typename Grid::LeafIntersection &  intersection ) const

inline

return insertion index of boundary intersection

Parameters

[in]

intersection

Leaf intersection

insertVertex()

template<class Grid >

void Dune::MMeshImplicitGridFactory< Grid >::insertVertex ( const WorldVector &  pos )

inline

Insert a vertex into the macro grid.

Parameters

[in]

pos

position of the vertex (in world coordinates)

Note

This method assumes that the vertices are inserted consecutively with respect to their index.

isElement() [1/2]

template<class Grid >

template<int d = dimension>

std::enable_if_t< d==2, bool > Dune::MMeshImplicitGridFactory< Grid >::isElement ( const std::vector< unsigned int > &  v, Element_handle &  fh  ) const

inline

Returns if there is a face with the given vertices in the triangulation 2.

Parameters

[in]

v

indices of the element vertices

template<class Grid >

template<int d = dimension>

std::enable_if_t< d==3, bool > Dune::MMeshImplicitGridFactory< Grid >::isElement ( const std::vector< unsigned int > &  v, Element_handle &  fh  ) const

inline

Returns if there is a cell with the given vertices in the triangulation 3.

Parameters
