Detailed Description

template<int dim, typename Number, typename MemorySpace>
class ryujin::ScalarConservation::WaveSpeedEstimatorView< dim, Number, MemorySpace >

A view of the WaveSpeedEstimator that makes the interface available for a given dimension dim and choice of number type Number (which can be a scalar float, or double, as well as a VectorizedArray holding packed scalars).

use_greedy_wavespeed()

template<int dim, typename Number , typename MemorySpace >

DEAL_II_HOST_DEVICE_ALWAYS_INLINE bool ryujin::ScalarConservation::WaveSpeedEstimatorView< dim, Number, MemorySpace >::use_greedy_wavespeed ( ) const

inline

Return whether a greedy wavespeed estimate is used instead of a guaranteed upper bound on the maximal wavespeed.

Definition at line 218 of file wave_speed_estimator.h.

use_averaged_entropy()

template<int dim, typename Number , typename MemorySpace >

DEAL_II_HOST_DEVICE_ALWAYS_INLINE bool ryujin::ScalarConservation::WaveSpeedEstimatorView< dim, Number, MemorySpace >::use_averaged_entropy ( ) const

inline

Return whether an entropy inequality on the averaged Krŭzkov entropy is enforced.

Definition at line 227 of file wave_speed_estimator.h.

random_entropies()

template<int dim, typename Number , typename MemorySpace >

DEAL_II_HOST_DEVICE_ALWAYS_INLINE unsigned int ryujin::ScalarConservation::WaveSpeedEstimatorView< dim, Number, MemorySpace >::random_entropies ( ) const

inline

Return the number of random Krŭzkov entropies for which an entropy inequality is enforced.

compute() [1/2]

template<int dim, typename Number , typename MemorySpace >

DEAL_II_HOST_DEVICE_ALWAYS_INLINE Number ryujin::ScalarConservation::WaveSpeedEstimatorView< dim, Number, MemorySpace >::compute	(	const Number &	u_i,
		const Number &	u_j,
		const precomputed_type &	prec_i,
		const precomputed_type &	prec_j,
		const dealii::Tensor< 1, dim, Number > &	n_ij
	)		const

For two states u_i, u_j, precomputed values prec_i, prec_j, and a (normalized) "direction" n_ij compute an upper bound estimate for the wavespeed.

Note

Entropy inequalities for additional Krŭzkov entropies are only enforced on the host memory space.
