The Periodic Condition node adds a periodic boundary condition that can be used to reduce the model size by using symmetries and periodicities in the geometry and physics interfaces being modeled. This feature works well for cases like opposing parallel boundaries. In other cases, use a
Destination Selection section to control the destination. By default, it contains the selection that COMSOL Multiphysics identifies.
This section is available for specifying the destination boundaries, if needed, when the Manual Destination Selection option is selected in the context menu for the
Periodic Condition node. You can only select destination boundaries from the union of all source and destination boundaries.
