Detailed Description

template<int dim, int spacedim = dim>
class MappingCartesian< dim, spacedim >::InternalData

Storage for internal data of the mapping. See Mapping::InternalDataBase for an extensive description.

This includes data that is computed once when the object is created (in get_data()) as well as data the class wants to store from between the call to fill_fe_values(), fill_fe_face_values(), or fill_fe_subface_values() until possible later calls from the finite element to functions such as transform(). The latter class of member variables are marked as 'mutable'.

Member Data Documentation

cell_extents

template<int dim, int spacedim = dim>

Tensor<1, dim> MappingCartesian< dim, spacedim >::InternalData::cell_extents

mutable

Extents of the last cell we have seen in the coordinate directions, i.e., h_x, h_y, h_z.

Definition at line 236 of file mapping_cartesian.h.

inverse_cell_extents

template<int dim, int spacedim = dim>

Tensor<1, dim> MappingCartesian< dim, spacedim >::InternalData::inverse_cell_extents

mutable

Reciprocal of the extents of the last cell we have seen in the coordinate directions, i.e., h_x, h_y, h_z.

Definition at line 243 of file mapping_cartesian.h.

volume_element

template<int dim, int spacedim = dim>

double MappingCartesian< dim, spacedim >::InternalData::volume_element

mutable

The volume element

Definition at line 248 of file mapping_cartesian.h.

quadrature_points

template<int dim, int spacedim = dim>

std::vector<Point<dim> > MappingCartesian< dim, spacedim >::InternalData::quadrature_points

Location of quadrature points of faces or subfaces in 3d with all possible orientations. Can be accessed with the correct offset provided via QProjector::DataSetDescriptor. Not needed/used for cells.

Definition at line 255 of file mapping_cartesian.h.

update_each

UpdateFlags Mapping< dim, spacedim >::InternalDataBase::update_each

inherited

A set of update flags specifying the kind of information that an implementation of the Mapping interface needs to compute on each cell or face, i.e., in Mapping::fill_fe_values() and friends.

This set of flags is stored here by implementations of Mapping::get_data(), Mapping::get_face_data(), or Mapping::get_subface_data(), and is that subset of the update flags passed to those functions that require re-computation on every cell. (The subset of the flags corresponding to information that can be computed once and for all already at the time of the call to Mapping::get_data() – or an implementation of that interface – need not be stored here because it has already been taken care of.)
