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.

)
ObservePoint::DECLARE_INPUT_EXCEPTION ( ExcNoObserveElement  ,
<< "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 67 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

Here is the caller graph for this function:

arma::vec3 ObservePoint::global_coords ( ) const
inline

Return global coordinates of the observation point.

Definition at line 73 of file observe.hh.

bool ObservePoint::have_observe_element ( )
