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 266 of file observe.cc.

Observe::~Observe

(

)

Destructor, must close the file.

Definition at line 299 of file observe.cc.

Member Function Documentation

template<int spacedim, class Value >

void Observe::compute_field_values

(

Field< spacedim, Value > &

field

)

Evaluates and store values of the given field in the observe points.

Definition at line 305 of file observe.cc.

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 169 of file observe.hh.

void Observe::output_header

(

)

Output file header.

Definition at line 350 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.
