Member Function Documentation

prepare()

template<typename Description , int dim, typename Number >

void ryujin::StubParabolicModule< Description, dim, Number >::prepare ( )

inline

Prepare time stepping. A call to prepare() allocates temporary storage and is necessary before any of the following time-stepping functions can be called.

Definition at line 65 of file stub_parabolic_module.h.

reinit_state_vector()

template<typename Description , int dim, typename Number >

void ryujin::StubParabolicModule< Description, dim, Number >::reinit_state_vector ( StateVector &  ) const

inline

(Re)initialize the parabolic state vector component of the state vector.

Note

This routine does not modify the hyperbolic state vector or the precomputed vector component.

Definition at line 83 of file stub_parabolic_module.h.

prepare_state_vector()

template<typename Description , int dim, typename Number >

void ryujin::StubParabolicModule< Description, dim, Number >::prepare_state_vector ( StateVector &  , Number    ) const

inline

This function preprocesses a given state vector U in preparation for a high order IMEX time step. This function exists because some time stepping variants have to precompute quantities before we can perform an IMEX step. In addition, this function is called whenever we perform a mesh transfer or output operation.

Definition at line 95 of file stub_parabolic_module.h.

backward_euler_step()

template<typename Description , int dim, typename Number >

template<int stages>

void ryujin::StubParabolicModule< Description, dim, Number >::backward_euler_step ( const StateVector &  old_state_vector, const Number  , std::array< std::reference_wrapper< const StateVector >, stages >  , const std::array< Number, stages >  , StateVector &  new_state_vector, Number    ) const

inline

Given a reference to a previous state vector old_U at time old_t and a time-step size tau perform an implicit backward euler step (and store the result in new_U).

The function takes an optional array of states stage_U together with a an array of weights stage_weights to construct a modified high-order right-hand side / flux.

Definition at line 114 of file stub_parabolic_module.h.

crank_nicolson_step()

template<typename Description , int dim, typename Number >

void ryujin::StubParabolicModule< Description, dim, Number >::crank_nicolson_step ( const StateVector &  old_state_vector, const Number  , StateVector &  new_state_vector, Number    ) const

inline

Given a reference to a previous state vector old_U at time old_t and a time-step size tau perform an implicit Crank-Nicolson step (and store the result in new_U).

This variant is used in the TimeIntegrator class for the Strang split variants.

Definition at line 137 of file stub_parabolic_module.h.

set_id_violation_strategy()

template<typename Description , int dim, typename Number >

void ryujin::StubParabolicModule< Description, dim, Number >::set_id_violation_strategy ( const IDViolationStrategy &  ) const

inline

Sets the invariant domain violation strategy.

Definition at line 152 of file stub_parabolic_module.h.

print_solver_statistics()

template<typename Description , int dim, typename Number >

void ryujin::StubParabolicModule< Description, dim, Number >::print_solver_statistics ( std::ostream &  ) const

inline

Print a status line with solver statistics. This function is used for constructing the status message displayed periodically in the TimeLoop.

Definition at line 169 of file stub_parabolic_module.h.

n_restarts()

template<typename Description , int dim, typename Number >

unsigned int ryujin::StubParabolicModule< Description, dim, Number >::n_restarts ( ) const

inline

The number of restarts signalled by the step() function.

Definition at line 177 of file stub_parabolic_module.h.

n_corrections()

template<typename Description , int dim, typename Number >

unsigned int ryujin::StubParabolicModule< Description, dim, Number >::n_corrections ( ) const

inline

The number of corrections performed by the step() function. This function exists to mirror the ParabolicModule interface and will always return 0.

Definition at line 187 of file stub_parabolic_module.h.

n_warnings()

template<typename Description , int dim, typename Number >

unsigned int ryujin::StubParabolicModule< Description, dim, Number >::n_warnings ( ) const

inline

The number of ID violation warnings encountered in the step() function.
