Use the Periodic Pair node, selected from the Pairs menu, to specify a pair where the periodic condition is applied to the magnetic vector potential. It is used to constrain continuity in a linear periodic machine where only a finite part is modeled. This node is different from the Periodic Condition feature that does not apply to pairs.

From the Pairs selection list, choose the pair which defines the source and destination boundaries.
