  • conn_b – Connectivity of mesh “b” [nelem, nne].

  • overlapping_nodes_b – Node-numbers of mesh “b” that overlap with mesh “a” [n].

  • check_position – If true the nodes are checked for position overlap.

  • rtol – Relative tolerance for check on position overlap.

  • atol – Absolute tolerance for check on position overlap.
