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 166 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.

Definition at line 412 of file mesh_adaptor.template.h.

References ryujin::fixed_time_points, ryujin::global_refinement, ryujin::random_adaptation, ryujin::simulation_cycle, and ryujin::smoothness_indicators.

◆ 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 adapation step in the current cycle. The analyze() method will set this boolean to true whenever the selected adaptation strategy advices to perform an adaptation cycle.

Definition at line 164 of file mesh_adaptor.h.

◆ 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.

◆ 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 176 of file mesh_adaptor.h.

◆ 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.

◆ 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.
