Typedef Documentation

ScalarHostVector

template<typename Number >

using ryujin::Vectors::ScalarHostVector = typedef dealii::LinearAlgebra::distributed::Vector<Number>

A scalar vector representing a single component given by a deal.II data type that is compatible with deal.II functions and methods and lives in the host memory space.

Definition at line 35 of file state_vector.h.

BlockHostVector

template<typename Number >

using ryujin::Vectors::BlockHostVector = typedef dealii::LinearAlgebra::distributed::BlockVector<Number>

A block vector representing a multiple components given by a deal.II data type that is compatible with deal.II functions and methods and lives in the host memory space.

Definition at line 44 of file state_vector.h.

ScalarVector

template<typename Number >

using ryujin::Vectors::ScalarVector = typedef MultiComponentVector<Number, 1>

A scalar vector representing a single component.

Definition at line 52 of file state_vector.h.

StateVector

template<typename Number , unsigned int problem_dim, unsigned int prec_dim>

using ryujin::Vectors::StateVector = typedef std::tuple< MultiComponentVector<Number, problem_dim> , MultiComponentVector<Number, prec_dim> , BlockHostVector<Number> >

A compound state vector formed by a std::tuple consisting of the hyperbolic state vector U, precomputed values, and an "parabolic state" vector stored as a BlockVector. All of these vectors have in common that they are associated with a hyperbolic, or parabolic state and precomputed data (derived from the hyperbolic state) for point in time.

Definition at line 64 of file state_vector.h.

Function Documentation

debug_poison_invalid_values()

template<typename Number , int prob_dim, int prec_dim, typename OfflineData >

void ryujin::Vectors::debug_poison_invalid_values	(	StateVector< Number, prob_dim, prec_dim > &	state_vector,
		const OfflineData &	offline_data
	)

A small helper function that sets all values of the hyperbolic vector that are invalid after a hyperbolic substep to a NaN value. This includes:

• the entire precomputed state vector
• constrained degrees of freedom of the hyperbolic state vector
• the ghost range of the hyperbolic state vector

Definition at line 79 of file state_vector.h.
