Detailed Description

template<int dim>
class ryujin::Geometries::GeoTIFFProfile< dim >

A modified rectangular domain, where the bottom boundary is described by an elevation profile read from a GeoTIFF file. By convention, the negative y-direction points to the bottom boundary.

The rectangular mesh is aligned with the profile (see MeshAlignment) and the cells above the profile form the new mesh, where cut cells are replaced by triangles (see CutCellDecomposition).

Note

Only implemented in 2D.

Member Function Documentation

create_coarse_triangulation()

template<int dim>

void ryujin::Geometries::GeoTIFFProfile< dim >::create_coarse_triangulation ( dealii::Triangulation< dim > &  triangulation ) const

inlinefinalvirtual

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

Implements ryujin::Geometry< dim >.

References ryujin::Geometries::RectangularDomain< dim >::boundary_bottom_, ryujin::GeoTIFFReader::compute_height(), and ryujin::Geometries::RectangularDomain< dim >::create_coarse_triangulation().

update_dof_handler()

template<int dim>

void ryujin::Geometries::GeoTIFFProfile< dim >::update_dof_handler ( dealii::DoFHandler< dim > &  ) const

inlinefinalvirtual

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.

Reimplemented from ryujin::Geometry< dim >.

populate_hp_collections()

template<int dim>

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

inlinefinalvirtual

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 from ryujin::Geometry< dim >.
