Constructor & Destructor Documentation

Geometry()

template<int dim>

ryujin::Geometry< dim >::Geometry ( const std::string &  name, const std::string &  subsection  )

inline

Constructor taking geometry name name and a subsection subsection as an argument. The dealii::ParameterAcceptor is initialized with the subsubsection subsection + "/" + name.

create_coarse_triangulation()

template<int dim>

virtual void ryujin::Geometry< dim >::create_coarse_triangulation ( dealii::Triangulation< dim > &  triangulation ) const

pure virtual

Create a coarse triangulation representing the current Geometry. This virtual method needs to be implemented in a derived classes.

Implemented in ryujin::Geometries::Airfoil< dim >, ryujin::Geometries::Annulus< dim >, ryujin::Geometries::Cylinder< dim >, ryujin::Geometries::Disk< dim >, ryujin::Geometries::GeoTIFFProfile< dim >, ryujin::Geometries::Reader< dim >, ryujin::Geometries::Step< dim >, ryujin::Geometries::WaveTank< dim >, ryujin::Geometries::TwoTanks< dim >, ryujin::Geometries::Wall< dim >, and ryujin::Geometries::RectangularDomain< dim >.

update_dof_handler()

template<int dim>

virtual void ryujin::Geometry< dim >::update_dof_handler ( dealii::DoFHandler< dim > &  ) const

inlinevirtual

This method is called before we distribute dofs and can be used to set the correct active FE index for each active cell for the given DoFHandler, or update material, or manifold ids, etc.

This method can be left empty for a standard geometry that only uses only one reference element. The method must be reimplemented for geometries that use hp capabilities, such as meshes with mixed finite elements, or meshes with FE_Nothing.

populate_hp_collections()

template<int dim>

virtual HP_Collection ryujin::Geometry< dim >::populate_hp_collections ( const unsigned int  , typename ryujin::Discretization< dim >::Collection &    ) const

inlinevirtual

Populate all hp::*Collection objects for finite elements, mappings, and quadratures. As this is a formidable zoo of different collection objects, we get a writable reference to the discretization object to set them directly.

Reimplemented in ryujin::Geometries::Reader< dim >, and ryujin::Geometries::RectangularDomain< dim >.

Member Data Documentation

transformation_

template<int dim>

std::function<dealii::Point<dim>( const typename dealii::Triangulation<dim>::cell_iterator &, const dealii::Point<dim> &)> ryujin::Geometry< dim >::transformation_

mutableprotected

Return the (optional) forward transformation that maps points of the undeformed triangulation created by create_coarse_triangulation() (and its refinements) to the actual geometry.

If the function is nonempty the Discretization class refines the triangulation without manifolds and realizes the geometry with a MappingQCache whose support points are computed with this transformation. If the function object is empty then a standard MappinQ is used instead. Return the name of the geometry as (const reference) std::string The transformation function object which should be set in create_coarse_triangulation() of derived classes that need MappingQCache to be set up.
