Detailed Description

Class representing single observe point, used internally by the class Observe. Members: input_pos_, snap_dim_, snap_region_name_ are set in constructor. Should be checked before passed in. Members: element_idx_, global_coords_, local_coords_ are derived, set in Observe::find_observe_points.

Constructor & Destructor Documentation

ObservePoint::ObservePoint ( )

protected

Default constructor just for testing.

Definition at line 141 of file observe.cc.

ObservePoint::ObservePoint ( Input::Record  in_rec, Mesh &  mesh, unsigned int  point_idx  )

protected

Constructor. Read from input.

ObservePoint::DECLARE_INPUT_EXCEPTION	(	ExcNoInitialPoint	,
		<< "Failed to find the element containing the initial observe point.\n"
	)

		<< "Failed to find the observe element with snap region: "<< EI_RegionName::qval<< " close to the initial observe point. Change maximal distance of observe element."<< "\n"
	)

unsigned int ObservePoint::element_idx ( ) const

inline

Return index of observation point in the mesh.

Definition at line 75 of file observe.hh.

void ObservePoint::find_observe_point ( Mesh &  mesh )

protected

Find the observe element and the definitive observe point.

Algorithm:

1. find element containing the point (initial element)
2. check initial element for region match possibly set it as (observe element)
3. add neighbours into processing_list for the next level
4. while we have no observe element: pass through the processing list of the current level
5. if element match the region, project and clip the init point, update observe element.
6. snapping on the observe element
