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.

Constructor & Destructor Documentation

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

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 272 of file observe.cc.

Observe::~Observe ( )

Destructor, must close the file.

Definition at line 307 of file observe.cc.

Member Function Documentation

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 178 of file observe.hh.

void Observe::output_header ( )

Output file header.

Definition at line 341 of file observe.cc.

Here is the caller graph for this function:

void Observe::output_time_frame ( double time )

Write field values to the output file. Using the YAML format.

Definition at line 353 of file observe.cc.

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

inline

Return points_ vector

Definition at line 194 of file observe.hh.

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)
