Member Function Documentation

prepare()

template<typename Description , int dim, typename Number >

void ryujin::VTUOutput< Description, dim, Number >::prepare

Prepare VTU output. A call to prepare() allocates temporary storage and is necessary before schedule_output() can be called.

Calling prepare() allocates temporary storage for additional (dim + 5) scalar vectors of type OfflineData::scalar_type.

Definition at line 62 of file vtu_output.template.h.

schedule_output()

template<typename Description , int dim, typename Number >

void ryujin::VTUOutput< Description, dim, Number >::schedule_output	(	const vector_type &	U,
		const precomputed_type &	precomputed_values,
		std::string	name,
		Number	t,
		unsigned int	cycle,
		bool	output_full = true,
		bool	output_cutplanes = true
	)

Given a state vector U and a file name prefix name, the current time t, and the current output cycle cycle) schedule a solution output.

The function post-processes quantities synchronously, and (depending on configuration options) schedules the write-out asynchronously onto a background worker thread. This implies that U can again be modified once schedule_output() returned.

The booleans output_full controls whether the full vector field is written out. Correspondingly, output_cutplanes controls whether cells in the vicinity of predefined cutplanes are written out.

The function requires MPI communication and is not reentrant.

Definition at line 186 of file vtu_output.template.h.

need_to_prepare_step()

template<typename Description , int dim, typename Number = double>

auto & ryujin::VTUOutput< Description, dim, Number >::need_to_prepare_step ( ) const

inline

Return a boolean indicating whether Steps 0 to 2 of an explicit Euler step have to be prepared prior to scheduling output. This is the case if a precomputed value or alpha is used in the output process.

Definition at line 127 of file vtu_output.h.
