Detailed Description

This class takes care about the observe points in the output stream, storing observe values of the fields and their output in the YAML format.

◆ OutputDataFieldMap

typedef std::map< string, OutputDataPtr > Observe::OutputDataFieldMap

Definition at line 186 of file observe.hh.

◆ OutputDataPtr

typedef std::shared_ptr<ElementDataCacheBase> Observe::OutputDataPtr

Constructor & Destructor Documentation

◆ Observe()

Observe::Observe	(	string	observe_name,
		Mesh &	mesh,
		Input::Array	in_array,
		unsigned int	precision,
		std::string	unit_str
	)

Construct the observation object.

observe_name - base name of the output file, the equation name. mesh - the mesh used for search for the observe points in_array - the array of observe points

Definition at line 323 of file observe.cc.

◆ ~Observe()

Observe::~Observe ( )

Destructor, must close the file.

Definition at line 373 of file observe.cc.

Member Function Documentation

◆ flush_values()

void Observe::flush_values ( )

protected

Effectively writes the data into the observe stream.

Definition at line 423 of file observe.cc.

Here is the caller graph for this function:

◆ local_range()

Range< ObservePointAccessor > Observe::local_range ( ) const

Returns local range of observe points.

Definition at line 479 of file observe.cc.

◆ observed_elements()

const std::vector<unsigned int>& Observe::observed_elements ( ) const

inline

Provides a vector of element indices on which the observation values are evaluated. This can be used to evaluate derived fields only on these elements in the times not selected to full output.

Definition at line 206 of file observe.hh.

◆ output_header()

void Observe::output_header ( )

Output file header.

Definition at line 411 of file observe.cc.

Here is the caller graph for this function:

◆ output_time_frame()

void Observe::output_time_frame ( bool flush )

Sets next output time frame of observe. If the table is full, writes field values to the output file. Using the YAML format. Argument flush starts writing to output file explicitly.

Definition at line 452 of file observe.cc.

◆ point_ds()

const Distribution* Observe::point_ds ( ) const

inline

Return point distribution

Definition at line 229 of file observe.hh.

◆ points()

const std::vector<ObservePoint>& Observe::points ( ) const

inline

Return points_ vector

Definition at line 223 of file observe.hh.

◆ prepare_compute_data()

template<typename T >

ElementDataCache< T > & Observe::prepare_compute_data	(	std::string	field_name,
		double	field_time,
		unsigned int	n_rows,
		unsigned int	n_cols
	)

Prepare data for computing observe values.

Method:

check that all fields of one time frame are evaluated at the same time
find and return ElementDataCache of given field_name, create its if doesn't exist.

Parameters

field_name	Quantity name of founding ElementDataCache
field_time	Actual computing time
n_rows	Count of rows of data cache (used only if new cache is created)
n_cols	Count of columns of data cache (used only if new cache is created)
