Detailed Description

template<int dim, typename Number>
class ExaDG::MappingDoFVector< dim, Number >

A mapping class based on dealii::MappingQCache equipped with practical interfaces that can be used to initialize the mapping.

The two functions fill_grid_coordinates_vector() and initialize_mapping_q_cache() should become member functions of dealii::MappingQCache in dealii, rendering this class superfluous in ExaDG.

Member Function Documentation

fill_grid_coordinates_vector() [1/2]

template<int dim, typename Number >

void ExaDG::MappingDoFVector< dim, Number >::fill_grid_coordinates_vector ( dealii::Mapping< dim > const & mapping, VectorType & grid_coordinates, dealii::DoFHandler< dim > const & dof_handler ) const

inline

Extract the grid coordinates for a given external mapping and fill a dof-vector given a corresponding dealii::DoFHandler object.

fill_grid_coordinates_vector() [2/2]

template<int dim, typename Number >

void ExaDG::MappingDoFVector< dim, Number >::fill_grid_coordinates_vector ( VectorType & grid_coordinates, dealii::DoFHandler< dim > const & dof_handler ) const

inline

Extract the grid coordinates of the current mesh configuration described by the dealii::MappingQCache object and fill a dof-vector given a corresponding dealii::DoFHandler object.

get_mapping()

template<int dim, typename Number >

std::shared_ptr< dealii::Mapping< dim > const > ExaDG::MappingDoFVector< dim, Number >::get_mapping ( ) const

inline

returns the deal.ii mapping object that describes the deformed mapping

initialize_mapping_from_dof_vector()

template<int dim, typename Number >

void ExaDG::MappingDoFVector< dim, Number >::initialize_mapping_from_dof_vector ( std::shared_ptr< dealii::Mapping< dim > const > mapping, VectorType const & displacement_vector, dealii::DoFHandler< dim > const & dof_handler )

inline

Initializes the dealii::MappingQCache object by providing a mapping that describes an undeformed reference configuration and a displacement dof-vector (with a corresponding dealii::DoFHandler object) that describes the displacement of the mesh compared to that reference configuration. There are two special cases:

If the mapping pointer is invalid, this implies that the reference coordinates are interpreted as zero, i.e., the displacement vector describes the absolute coordinates of the grid points.

If the displacement_vector is empty or uninitialized, this implies that no displacements will be added to the grid coordinates of the reference configuration described by mapping.
