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 list, choose From list (the default), All, All contact pairs, or All identity pairs. If you choose From list, select the pairs where you want to impose continuity across the pair boundaries by clicking the Add button () and choose the pairs to add from the list in the Add dialog that opens; then click OK.
