Detailed Description

template<int dim>
class aspect::GeometryModel::internal::ChunkGeometry< dim >

ChunkGeometry is a class that implements the interface of ChartManifold. The function push_forward takes a point in the reference (radius,lon,lat) domain and transforms it into real space (cartesian). The inverse function pull_back reverses this operation. The push_forward_gradient provides derivatives of the reference coordinates to the real space coordinates, which are used in computing normal vectors. The transformations can include topography added to the initially radially symmetric mesh.

override

This function receives a point in spherical coordinates radius, longitude, latitude and returns cartesian coordinates x, y and z, including any initially prescribed topography.

push_forward_gradient()

template<int dim>

DerivativeForm<1, dim, dim> aspect::GeometryModel::internal::ChunkGeometry< dim >::push_forward_gradient ( const Point< dim > &  chart_point ) const

override

This function provides the derivatives of the push_forward function to the spherical coordinates, which are needed in the computation of vectors tangential to the domain boundaries.

pull_back_sphere()

get_radius()

template<int dim>

double aspect::GeometryModel::internal::ChunkGeometry< dim >::get_radius

(

const Point< dim > &

)

const

This function computes the outer radius of the domain at the longitude (and latitude) of the given point (given in cartesian coordinates), i.e. the unperturbed outer radius + the topography.

set_min_longitude()

template<int dim>

virtual void aspect::GeometryModel::internal::ChunkGeometry< dim >::set_min_longitude ( const double  p1_lon )

virtual

Set the minimum longitude of the domain, which is used in pulling back cartesian coordinates to spherical to get the longitude in the correct quarter.

clone()
