Detailed Description

Computes element-to-element and node-to-node connectivity for finite element meshes.

This class computes entity-to-entity connectivities (node/edge/face/facet/element/ control point, plus thin-shell element neighbours) on the mesh it is given, in serial on the calling rank.

Key features:

Uses efficient vector+sort+unique approach instead of bitsets for sparse connectivity
Handles thin-shell ghost facets when linking edges, faces and elements across layers

◆ connect_elements_to_elements()

void belfem::mesh::ConnectivityCalculator::connect_elements_to_elements ( )

Compute element-to-element connectivity.

For each element, finds all other elements that share a facet with it (an edge in 2D, a face in 3D). When thin shells exist, the pass is repeated on the thin-shell blocks alone so that layer elements are linked to their in-layer neighbours.

◆ connect_nodes_to_nodes()

void belfem::mesh::ConnectivityCalculator::connect_nodes_to_nodes ( )

Compute node-to-node connectivity.

For each node, finds all other nodes that share at least one element with it (all elements attached to the node are considered).
