Function documentation

static void atlas::mesh::actions::ReorderImpl::reorderNodes(Mesh& mesh, const std::vector<idx_t>& order)

Reorder the nodes in the given mesh using a given order

  • All fields in mesh.nodes() are reordered.
  • mesh.cells().node_connectivity() gets updated
  • mesh.edges().node_connectivity() gets updated

void atlas::mesh::actions::ReorderImpl::operator()(Mesh&) virtual

Reorder the nodes in the given mesh using the order computed with the computeNodesOrder function Then apply reorderCellsUsingNodes and reorderEdgesUsingNodes
