Member Function Documentation

prepare()

template<typename Description , int dim, typename Number >

void ryujin::MeshAdaptor< Description, dim, Number >::prepare

(

const Number

t

)

Prepare temporary storage and clean up internal data for the analyze() facility.

Definition at line 168 of file mesh_adaptor.template.h.

analyze()

template<typename Description , int dim, typename Number >

void ryujin::MeshAdaptor< Description, dim, Number >::analyze	(	const StateVector &	state_vector,
		const Number	t,
		unsigned int	cycle
	)

Analyze the given StateVector with the configured adaptation strategy and time point selection strategy and decide whether a mesh adaptation cycle should be performed.

mark_cells_for_coarsening_and_refinement()

template<typename Description , int dim, typename Number >

void ryujin::MeshAdaptor< Description, dim, Number >::mark_cells_for_coarsening_and_refinement

(

dealii::Triangulation< dim > &

triangulation

)

const

Mark cells for coarsening and refinement with the configured mesh adaptation and marking strategies.

compute_smoothness_indicators()

template<typename Description , int dim, typename Number >

void ryujin::MeshAdaptor< Description, dim, Number >::compute_smoothness_indicators

(

const StateVector &

state_vector

)

const

Compute smoothness indicators. This function reinitializes and populates the smoothness_indicators() vector.

Definition at line 420 of file mesh_adaptor.template.h.

References ryujin::have_separate_memory_spaces.

need_mesh_adaptation()

template<typename Description , int dim, typename Number = double>

const auto & ryujin::MeshAdaptor< Description, dim, Number >::need_mesh_adaptation ( ) const

inline

A boolean indicating whether we should perform a mesh adaptation step in the current cycle. The analyze() method will set this boolean to true whenever the selected adaptation strategy advises to perform an adaptation cycle.

Definition at line 189 of file mesh_adaptor.h.

indicators()

template<typename Description , int dim, typename Number = double>

const auto & ryujin::MeshAdaptor< Description, dim, Number >::indicators ( ) const

inline

The computed cell indicators.

Definition at line 194 of file mesh_adaptor.h.

smoothness_indicators()

template<typename Description , int dim, typename Number = double>

const auto & ryujin::MeshAdaptor< Description, dim, Number >::smoothness_indicators ( ) const

inline

The computed smoothness indicators. The vector is only valid if the "smoothness indicator" refinement strategy has been selected.
