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 129 of file mesh_adaptor.template.h.

References ryujin::fixed_time_points.

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 236 of file mesh_adaptor.template.h.

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

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.

const

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