Detailed Description

template<int dim>
class aspect::GeometryModel::TwoMergedChunks< dim >

A geometry model class that describes a chunk of a spherical shell, but with two boundary indicators per side boundary. This allows for specifying two different types of boundary conditions on the side boundaries, for example prescribed plate motions along the edge of the lithosphere and an open boundary underneath. In 2D, this class simulates a sector with inner and outer radius, and minimum and maximum longitude. Longitude increases anticlockwise from the positive x-axis, as per the mathematical convention of phi. In 3D, the class simulates a chunk of a sphere, bounded by arbitrary lines of longitude, latitude and radius. Boundary indicator names are lowerwest, upperwest, lowereast, uppereast, lowersouth, uppersouth, lowernorth, uppernorth, bottom and top.

The parameters that describe this geometry and that are read from the input file are the inner, outer and middle boundary radius of the shell, the minimum and maximum longitude, minimum and maximum longitude, and the number of cells initialized in each dimension. In the radial direction, this number should be specified for both the lower and the upper part of the chunk (with their boundary lying at the middle boundary radius).

Initial topography can be added through a radial displacement of the mesh nodes.

Member Function Documentation

§ initialize()

template<int dim>

void aspect::GeometryModel::TwoMergedChunks< dim >::initialize ( )

overridevirtual

Initialization function. This function is called once at the beginning of the program after parse_parameters is run and after the SimulatorAccess (if applicable) is initialized. This function calls the initialize function of the manifold with a pointer to the initial topography model obtained from SimulatorAccess.

Reimplemented from aspect::Plugins::InterfaceBase.

§ create_coarse_mesh()

template<int dim>

void aspect::GeometryModel::TwoMergedChunks< dim >::create_coarse_mesh ( parallel::distributed::Triangulation< dim > & coarse_grid ) const

overridevirtual

Generate a coarse mesh for the geometry described by this class.

Implements aspect::GeometryModel::Interface< dim >.

§ get_used_boundary_indicators()

template<int dim>

std::set<types::boundary_id> aspect::GeometryModel::TwoMergedChunks< dim >::get_used_boundary_indicators ( ) const

overridevirtual

Return the set of boundary indicators that are used by this model. This information is used to determine what boundary indicators can be used in the input file.

The chunk model uses boundary indicators zero through 2*dim+2*(dim-1)-1, with the first two being the faces perpendicular to the radius of the shell, the next four along lines of longitude and, in 3d, the next four along lines of latitude.

Implements aspect::GeometryModel::Interface< dim >.

§ get_symbolic_boundary_names_map()

template<int dim>

std::map<std::string,types::boundary_id> aspect::GeometryModel::TwoMergedChunks< dim >::get_symbolic_boundary_names_map ( ) const

overridevirtual

Return a mapping from symbolic names of each part of the boundary to the corresponding boundary indicator. This allows users to specify names, not just numbers in their input files when describing which parts of the boundary have to satisfy which boundary conditions.

Reimplemented from aspect::GeometryModel::Interface< dim >.

§ length_scale()

template<int dim>

double aspect::GeometryModel::TwoMergedChunks< dim >::length_scale ( ) const

overridevirtual

Return the typical length scale one would expect of features in this geometry, assuming realistic parameters.

As described in the first ASPECT paper, a length scale of 10km = 1e4m works well for the pressure scaling for earth sized spherical shells. use a length scale that yields this value for the R0,R1 corresponding to earth but otherwise scales like (R1-R0)

Implements aspect::GeometryModel::Interface< dim >.

§ depth()

template<int dim>

double aspect::GeometryModel::TwoMergedChunks< dim >::depth ( const Point< dim > & position ) const

overridevirtual

Return the depth that corresponds to the given position. The documentation of the base class (see GeometryModel::Interface::depth()) describes in detail how "depth" is interpreted in general.

Computing a depth requires a geometry model to define a "vertical" direction. The current class considers the radial vector away from the origin as vertical and considers the "top" boundary as the surface. In almost all cases one will use a gravity model that also matches these definitions.

Implements aspect::GeometryModel::Interface< dim >.

§ height_above_reference_surface()

template<int dim>

double aspect::GeometryModel::TwoMergedChunks< dim >::height_above_reference_surface ( const Point< dim > & position ) const

overridevirtual

Return the height of the given position relative to the outer radius.

Implements aspect::GeometryModel::Interface< dim >.

§ representative_point()

template<int dim>

Point<dim> aspect::GeometryModel::TwoMergedChunks< dim >::representative_point ( const double depth ) const

overridevirtual

Returns a representative point for a given depth. Such a point must lie inside the domain for sure (assuming the given depth is valid), but it is not important where exactly in the domain it is. A good choice would be on a middle axis, for example.

The function is used, for example, in computing an initial adiabatic profile. For this, we need to be able to query the density as a function of (adiabatic) pressure and temperature. However, the functions returning the density from the material model also depend on location. Since we are interested only in computing a depth-dependent adiabatic profile without lateral variation, we need to be able to query the density at "representative points" at given depths, without caring too much where exactly that is – but at points that we know for sure are inside the domain.

Implements aspect::GeometryModel::Interface< dim >.

§ west_longitude()

template<int dim>

virtual double aspect::GeometryModel::TwoMergedChunks< dim >::west_longitude ( ) const

Implements aspect::GeometryModel::Interface< dim >.

§ inner_radius()

template<int dim>

virtual double aspect::GeometryModel::TwoMergedChunks< dim >::inner_radius ( ) const

Return the inner radius of the chunk measured in meters.

§ outer_radius()

template<int dim>

virtual double aspect::GeometryModel::TwoMergedChunks< dim >::outer_radius ( ) const

virtual

Return the outer radius of the chunk measured in meters.

§ has_curved_elements()

template<int dim>

bool aspect::GeometryModel::TwoMergedChunks< dim >::has_curved_elements ( ) const

overridevirtual

If true, the geometry contains cells with boundaries that are not straight and have a deal.II boundary object attached to it. If the return value is false, certain operation can be optimized.The default implementation of this function will return true.

A chunk has curved boundaries and cells, so return true.

Reimplemented from aspect::GeometryModel::Interface< dim >.

§ point_is_in_domain()

template<int dim>

bool aspect::GeometryModel::TwoMergedChunks< dim >::point_is_in_domain ( const Point< dim > & point ) const

Implements aspect::GeometryModel::Interface< dim >.

§ natural_coordinate_system()

template<int dim>

aspect::Utilities::Coordinates::CoordinateSystem aspect::GeometryModel::TwoMergedChunks< dim >::natural_coordinate_system ( ) const

overridevirtual

Implements aspect::GeometryModel::Interface< dim >.

§ cartesian_to_natural_coordinates()

template<int dim>

std::array<double,dim> aspect::GeometryModel::TwoMergedChunks< dim >::cartesian_to_natural_coordinates ( const Point< dim > & position ) const

overridevirtual

Takes the Cartesian points (x,z or x,y,z) and returns standardized coordinates which are most 'natural' to the geometry model. For a chunk this is (radius, longitude) in 2d and (radius, longitude, latitude) in 3d.

Reimplemented from aspect::GeometryModel::Interface< dim >.

§ natural_to_cartesian_coordinates()

template<int dim>

Point<dim> aspect::GeometryModel::TwoMergedChunks< dim >::natural_to_cartesian_coordinates ( const std::array< double, dim > & position ) const

overridevirtual

Undoes the action of cartesian_to_natural_coordinates, and turns the coordinate system which is most 'natural' to the geometry model into Cartesian coordinates.

Reimplemented from aspect::GeometryModel::Interface< dim >.

§ use_merged_grids

template<int dim>

bool aspect::GeometryModel::TwoMergedChunks< dim >::use_merged_grids

private

Whether to make the grid by gluing together two chunks, or just use one chunk to make the grid. Using two grids glued together is a safer option, since it forces the boundary conditions to be always applied to the same depth, but one unified grid allows for a more flexible usage of the adaptive refinement.

Definition at line 261 of file two_merged_chunks.h.

§ point1

template<int dim>

Point<dim> aspect::GeometryModel::TwoMergedChunks< dim >::point1

private

Minimum longitude-depth (2D) or longitude-latitude-depth (3D) point of the entire merged chunk.

Definition at line 268 of file two_merged_chunks.h.

§ point2

template<int dim>

Point<dim> aspect::GeometryModel::TwoMergedChunks< dim >::point2

private

Maximum longitude-depth (2D) or longitude-latitude-depth (3D) point of the entire merged chunk.

Definition at line 275 of file two_merged_chunks.h.

§ point3

template<int dim>

Point<dim> aspect::GeometryModel::TwoMergedChunks< dim >::point3

private

Minimum longitude-depth (2D) or longitude-latitude-depth (3D) point for the upper chunk.

Definition at line 282 of file two_merged_chunks.h.

§ point4

template<int dim>

Point<dim> aspect::GeometryModel::TwoMergedChunks< dim >::point4

private

Maximum longitude-depth (2D) or longitude-latitude-depth (3D) point for the lower chunk.

Definition at line 289 of file two_merged_chunks.h.

§ lower_repetitions

template<int dim>

std::array<unsigned int, dim> aspect::GeometryModel::TwoMergedChunks< dim >::lower_repetitions

private

The number of cells in each coordinate direction for the lower and upper chunk.

Definition at line 295 of file two_merged_chunks.h.

§ upper_repetitions

template<int dim>

std::array<unsigned int, dim> aspect::GeometryModel::TwoMergedChunks< dim >::upper_repetitions

private

Definition at line 296 of file two_merged_chunks.h.

§ manifold

template<int dim>

std::unique_ptr<const internal::ChunkGeometry<dim> > aspect::GeometryModel::TwoMergedChunks< dim >::manifold

private

An object that describes the geometry. This pointer is initialized in the initialize() function, and serves as the manifold object that the triangulation is later given in create_coarse_mesh() where the triangulation clones it.

The object is marked as 'const' to make it clear that it should not be modified once created. That is because the triangulation copies it, and modifying the current object will not have any impact on the manifold used by the triangulation.

Definition at line 309 of file two_merged_chunks.h.

§ my_manifold_id

template<int dim>

constexpr types::manifold_id aspect::GeometryModel::TwoMergedChunks< dim >::my_manifold_id = 15

staticprivate

Give a symbolic name to the manifold id to be used by this class.
