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.

unsigned int ObservePoint::element_idx ( ) const

inline

Return index of observation point in the mesh.

Definition at line 90 of file observe.hh.

void ObservePoint::find_observe_point ( Mesh & mesh )

protected

Find the observe element and the definitive observe point.

Algorithm:

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