void Mesh::make_neighbours_and_edges ( )

protected

This replaces read_neighbours() in order to avoid using NGH preprocessor.

TODO:

Avoid maps:

4) replace EdgeVector by std::vector<Edge> (need not to know the size)

5) need not to have temporary array for Edges, only postpone setting pointers in elements and set them after edges are found; we can temporary save Edge index instead of pointer in Neigbours and elements

6) Try replace Edge * by indexes in Neigbours and elements (anyway we have mesh pointer in elements so it is accessible also from Neigbours)

TODO:

use std::is_any for setting is_neigbour
possibly make appropriate constructors for Edge and Neighbour
check side!=-1 when searching neigbouring element
process bc_elements first, there should be no Neigh, but check it set Edge and boundary there

Definition at line 383 of file mesh.cc.

Here is the caller graph for this function:

unsigned int Mesh::max_edge_sides ( unsigned int dim ) const

inline
